Description

  The present invention relates to an information processing apparatus, an information processing method, and an information processing program.

  One interface for instructing the information processing apparatus to execute processing is a CLI (Command Line Interface). The CLI is a user interface of a format in which a specific character string is input using a keyboard to instruct the information processing apparatus to execute processing, and a processing execution result is acquired by character output. Compared with GUI (Graphical User Interface), CLI is widely used because it has many advantages such as low processing load and light operation, and high flexibility of operating environment. Yes.

  Further, the following techniques have been proposed for processing execution instructions to the information processing apparatus. For example, an information processing apparatus has been proposed in which the validity of each character is judged when a command is input, and an error is displayed immediately if there is no validity. Also, the procedure is executed based on the parameters specified for each function, and if there is an error in the parameters during the execution, the procedure is interrupted and an abnormal message is displayed. A system for resuming a procedure from a function whose parameters have been corrected has been proposed.

  Incidentally, control information stored in the information processing apparatus is referred to in order to verify whether or not a process according to a command input through the CLI can be executed. In recent years, as the processing executed by the information processing apparatus becomes more complicated, a large number of control information is stored in the information processing apparatus, and a large number of control information is referred to even during the above verification. It is like that. Since it takes a long time to refer to such an enormous number of control information, there is a problem that it takes a long time from the start of command input until the processing corresponding to the command is completed.

  In one aspect, an object of the present invention is to provide an information processing apparatus, an information processing method, and an information processing program capable of shortening a time from input of a command to completion of processing corresponding to the command.

  In one proposal, an information processing apparatus that executes processing according to a command is provided. The information processing apparatus includes a storage unit, a command reception unit, an information collection unit, and a process execution unit as described below. The storage unit stores a plurality of command names that can be received by the information processing apparatus and a plurality of control information used for processing of the information processing apparatus. The command receiving unit receives character input and determines whether one command name that matches a character string input from a plurality of command names can be determined each time one character is input. When one command name is determined, the information collection unit starts collecting verification information for verifying whether or not processing according to the one command name can be executed from among a plurality of control information. The process execution unit verifies whether or not execution is possible based on the collected verification information, and executes a process corresponding to one command name when it is determined that the execution is possible.

Further, in one proposal, an information processing method is provided in which processing similar to that of the information processing apparatus is executed by a computer.
Furthermore, in one proposal, an information processing program for causing a computer to execute the same processing as that of the above information processing apparatus is provided.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[First Embodiment]
FIG. 1 is a diagram illustrating a configuration example and a processing example of the information processing apparatus according to the first embodiment. The information processing apparatus 10 executes processing according to the input command. The information processing apparatus 10 is realized as a computer, for example.

Note that screens 21 to 24 shown in FIG. 1 respectively show screen display examples of command input screens in which commands are input.
The information processing apparatus 10 includes a storage unit 11, a command reception unit 12, an information collection unit 13, and a process execution unit 14. The storage unit 11 is realized as a storage device such as a random access memory (RAM) or a hard disk drive (HDD), for example. The processes of the command reception unit 12, the information collection unit 13, and the process execution unit 14 are realized by, for example, a processor included in the information processing apparatus 10 executing a predetermined program.

  The storage unit 11 stores a plurality of command names that can be received by the information processing apparatus and a plurality of control information used for processing of the information processing apparatus 10. In the example of FIG. 1, the storage unit 11 stores a command list 11a in which the plurality of command names are registered and a control information list 11b in which the plurality of control information is registered.

  The command receiving unit 12 receives input of characters in accordance with user operations. The command receiving unit 12 estimates the input command name each time one character is input while referring to the command list 11a (step S1). That is, each time one character is input, the command receiving unit 12 determines whether or not a single command name that matches the input character string can be determined from the command names registered in the command list 11a.

  For example, assume that “create” is entered on the command input screen. In the command list 11a, “create volume” and “create raid-group” are registered as command names. For this reason, the command receiving unit 12 cannot uniquely determine the command name at this point. However, after that, when “v” is input as shown in the screen 21, the only command name that matches the input character string is determined as “create volume” (step S2). That is, the command name is determined before the entire command name “create volume” is input. For example, when the command name is confirmed, the command receiving unit 12 displays the confirmed command name on the command input screen as shown in the screen 23.

  When the command name is fixed to “create volume” by the command receiving unit 12, the information collecting unit 13 determines whether or not to execute the process according to “create volume” from the plurality of control information in the control information list 11b. A process of collecting verification information for verification is started (step S3). For example, the control information to be collected as the verification information is determined according to the determined command name.

  The process execution unit 14 verifies whether or not the process according to “create volume” can be executed based on the verification information collected by the information collection unit 13 (step S4). For example, it is assumed that the information processing apparatus 10 executes processing according to a command statement including a command name and one or more option information that follows the command name. In this case, the process execution unit 14 verifies the above-described execution feasibility by verifying the consistency between the option information input following the confirmed command name “create volume” and the collected verification information. To do. In the example of FIG. 1, option information “name 01” is input after the command name “create volume” as shown on the screen 23.

  If the process execution unit 14 determines that the execution is possible by verifying the execution possibility, the process execution unit 14 executes a process according to the confirmed command name “create volume” (step S5). When the process is normally executed, the command input screen waits for the input of the next command as shown in the screen 24.

  According to the information processing apparatus 10 described above, the command name is determined before the entire command name is input, and collection of verification information for verifying whether or not the process according to the determined command name can be executed is started. it can. This makes it possible to shorten the time from the start of command name input to the completion of processing corresponding to the command name, rather than starting the collection of verification information after the entire command name is input.

[Second Embodiment]
Next, a case where a storage control apparatus is applied as an example of the information processing apparatus 10 in FIG. 1 will be described as a second embodiment.

  FIG. 2 is a diagram illustrating a configuration example of a storage system according to the second embodiment. The storage system shown in FIG. 2 has a CE (Controller Enclosure) 50 and a DE (Drive Enclosure) 200. The CE 50 includes CMs (Controller Modules) 100 and 100a connected to the DE 200, respectively. A host device 210 and a management terminal 220 are connected to the CMs 100 and 100a.

  The CM 100 is a storage control device that controls access to a storage device installed in the DE 200 in response to a request from the host device 210. For example, the CM 100 creates a logical volume that uses the storage device installed in the DE 200 as a real storage area, receives an access request for the logical volume from the host device 210, and executes access control according to the request. The CM 100a can execute the same processing as the CM 100.

  The DE 200 includes a plurality of storage devices to be accessed from the host device 210. In this embodiment, as an example, it is assumed that the DE 200 is a disk array device in which HDDs 201, 202, 203,... Are mounted as such storage devices. The storage device to be accessed from the host device 210 may be another type of nonvolatile storage device such as an SSD (Solid State Drive).

The host device 210 is, for example, a business server that executes processing using a storage device in the DE 200.
For example, one of the CMs 100 and 100a can operate as an active system and the other can operate as a standby system. In addition, for example, the CMs 100 and 100a can also receive from the host device 210 an access request for a logical volume set individually. In this case, for example, information stored in one of the CMs 100 and 100a may be backed up in the other. In addition, the CMs 100 and 100a may receive access requests for individual logical volumes from the individual host devices 210, respectively.

  Further, a plurality of CEs 50 and DEs 200 may be provided in the storage system. For example, a plurality of DEs 200 may be connected to the CMs 100 and 100a. In addition, individual DEs 200 may be connected to the CMs 100 and 100a, respectively. In this case, the physical storage area of the logical volume set in one of the CMs 100 and 100a may be realized using not only the DE 200 connected to one but also the DE 200 connected to the other. In this case, one CM may access the DE 200 connected to the other CM through the other CM.

  The management terminal 220 is a terminal device operated by an administrator who manages the storage system. A keyboard 221 and a display device 222 are connected to the management terminal 220. The administrator can cause the CMs 100 and 100a to execute various processes such as setting and status display by operating the management terminal 220 using the keyboard 221 while visually recognizing the display device 222. In the present embodiment, the CMs 100 and 100a provide the management terminal 220 with a CLI for instructing execution of such processing. In the case of operating the CM 100, a CLI screen based on information from the CM 100 is displayed on the display device 222. When the administrator inputs a command to the CLI screen using the keyboard 221, the input command is transmitted to the CM 100. Is done. The CM 100 executes processing according to the received command.

  Next, the hardware configuration of the CMs 100 and 100a will be described. Here, the CM 100 will be described as an example, but the CM 100a is also realized using the same hardware as the CM 100.

  FIG. 3 is a diagram illustrating a hardware configuration example of the CM. The CM 100 is realized as a computer as shown in FIG. 3, for example. The CM 100 includes a processor 101, a RAM 102, an SSD 103, a CA (Channel Adapter) 104, a DI (Drive Interface) 105, and a LAN (Local Area Network) interface 106. These components are connected via a bus 107.

  The processor 101 controls the CM 100 as a whole. The processor 101 may be a multiprocessor. The processor 101 is, for example, a central processing unit (CPU), a micro processing unit (MPU), a digital signal processor (DSP), an application specific integrated circuit (ASIC), or a programmable logic device (PLD). The processor 101 may be a combination of two or more elements among CPU, MPU, DSP, ASIC, and PLD.

  The RAM 102 is used as a main storage device of the CM 100. The RAM 102 temporarily stores at least part of an OS (Operating System) program and application programs to be executed by the processor 101. The RAM 102 stores various data necessary for processing by the processor 101.

The SSD 103 is used as an auxiliary storage device of the CM 100. The SSD 103 stores an OS program, application programs, and various data.
The CA 104 is an interface for communicating with the host device 210. The CA 104 and the host apparatus 210 are connected via a SAN (Storage Area Network) using, for example, Fiber Channel (FC) or iSCSI (Internet Small Computer System Interface).

The DI 105 is an interface for communicating with the DE 200. The DI 105 is, for example, a SAS (Serial Attached SCSI) interface.
The LAN interface 106 is an interface for communicating with the management terminal 220.

  The processing functions of the CM 100 are realized by the above hardware configuration. Note that the host device 210 and the management terminal 220 can also be realized as a computer having the same hardware configuration as the CM 100.

  Incidentally, as described above, the CMs 100 and 100 a provide the CLI to the management terminal 220. The CLI is a user interface in a format in which execution of processing is instructed by inputting a specific character string using a keyboard, and the execution result of processing is acquired by character output.

  In CLI, generally, a command name called a command prompt and a character string indicating input waiting are input, followed by a command name and one or more options corresponding to the command name, options, and so on. The command name and option, and the option and option are separated by a space. The processing content to be executed is specified by the command name, and the details of the processing content are specified by the option.

  Options are specified in a structure like “option name argument” when the user is allowed to specify an argument of any value. The option name and argument are separated by a space. An option may be specified only by an option name. When the Enter key is pressed following the input of the command name and one or more options, the command statement is confirmed and processing corresponding to the command statement is executed.

  Also in this embodiment, it is assumed that a command statement is input in the above-described format. Note that a one-line instruction sentence input from the command prompt until the Enter key is pressed is called a command line.

  On the other hand, in the CMs 100 and 100a, there are many logical operation targets that can be set and checked through the CLI. For example, there are logical volumes, RAID (Redundant Arrays of Inexpensive Disks) groups, storage pools, host groups, port groups, LUN (Logical Unit Number) groups, and the like. In addition, the CMs 100 and 100a are each equipped with a large number of physical devices whose operation status can be confirmed through the CLI. For example, there are disks (HDD and SSD), power supply units, CMs, CAs, and the like. Thus, the number of operation objects is enormous.

  In addition, when a plurality of CMs (for example, CMs 100 and 100a) operate in cooperation, the number of operation targets in one CM can be further increased. For example, a case where information stored in one of the CMs 100 and 100a is backed up in the other can be considered. Alternatively, an individual logical volume is set in each of the CMs 100 and 100a, and the physical storage area of the logical volume set in one CM uses not only the DE 200 connected to the CM but also the DE 200 connected to the other CM. There are cases where this is realized. In such a case, one CM needs to hold not only its own CM but also setting information related to the other CM. For this reason, the number of operation objects in each CM further increases.

  Since the operation target is enormous as described above, the CLI for managing the CMs 100 and 100a often has a very complicated command line structure. Therefore, you need to get used to entering the command line correctly. Often, the command line is re-entered many times until it can be entered correctly.

  Typical functions that can be operated through the CLI in the CMs 100 and 100a include, for example, various display functions, basic function setting functions, apparatus environment setting functions, maintenance functions, utility functions, and factory shipment functions. Various display functions include device status display and component status display. The basic function setting functions include RAID management, hot spare management, power saving management, volume management, LUN mapping, Host Affinity setting, various copy settings, and the like. Device environment setting functions include network setting, date setting, and SNMP (Simple Network Management Protocol) management. Maintenance functions include forced degeneration or installation, firmware application to each part, log collection, and dump collection. Utility functions include event notification, performance information display, error information display, and various types of recovery. Factory shipping functions include shipping settings and initialization.

  Here, FIG. 4 and FIG. 5 are diagrams showing a comparative example of command line input work. A processing example using the conventional processing method when a command line is input will be described with reference to FIGS.

  In the example of FIGS. 4 and 5, “create volume” instructing to create a new logical volume is specified as the command name. Further, after the command name, option names “type”, “size”, “name”, “rg-name”, “encryption”, “copy-protection”, and “exc” are designated.

  “Type” is an option name for specifying the type of the logical volume, and “open” is specified as an argument in the state 1-1 of FIG. 4 which is the initial state. “Size” is an option name that specifies the size of the logical volume. In state 1-1, “100 gb” (100 gigabytes) is specified as an argument. “Name” is an option name that specifies the name (Friendly name) of the logical volume. In state 1-1, “olun” is specified as an argument. “Rg-name” is an option name that designates the RAID group of the logical volume creation destination, and “RG # 0” is designated as an argument in state 1-1. “Encryption” is an option name that specifies whether to enable the encryption function in the logical volume, and “enable” indicating that it is enabled is specified in the state 1-1. “Copy-protection” is an option name that specifies whether to enable the copy restriction function for the logical volume, and “enable” indicating that it is enabled is specified in the state 1-1. “Exc” is an option name that specifies whether to enable the high-speed cache function for the logical volume, and “enable” indicating that it is enabled is specified in the state 1-1.

  In general, in CLI, when the completion of command line input is detected by pressing the Enter key (input of a line feed), the input content is analyzed and consistency check is performed. If it is determined by this process that a process based on the contents of the input command line can be executed, the execution of the process is started.

  The input contents are analyzed in order from the beginning of the command line. In addition, for each option described on the command line, consistency check is performed in order from the first option on the command line. In the consistency check, the consistency of the arguments included in the option is verified. In general, if there is even one option determined to be inconsistent, the input command line is discarded, and the user is requested to input again from the top of the command line.

  In the case of the command line shown in the state 1-1 of FIG. 4, first, consistency is checked for the first option name “type” and its argument “open”, and then the option name “size” and its argument “100gb”. Consistency is checked. Here, it is assumed that the argument “100 gb” is determined to be inconsistent. For example, it is determined that there is no consistency when the remaining amount of a physical area (for example, a storage pool) in which a logical volume is created is less than 100 gigabytes. In this case, for example, as shown in the state 1-1, error information indicating that the capacity is insufficient for the option name “size” is displayed on the CLI screen. Then, the command prompt (“CLI>”) is displayed on the next line, and re-input from the beginning of the command line is requested.

  Next, it is assumed that a command line in which the argument of the option name “size” is corrected to “1 gb” (1 gigabyte) is input as shown in the state 1-2. In this case, even if it is determined that the option name “size” is consistent, if it is determined that the next option name “name” is not consistent, error information is displayed and the command line is requested to be entered again. It is done. In this example, there is a condition that the volume name of the logical volume must be unique, and it is assumed that the input volume name “olun” has already been registered.

  Next, as shown in state 1-3, it is assumed that the volume name is corrected to a unique “olun # 01”, but the next option name “rg-name” is determined to be inconsistent. For example, it is assumed that the RAID group with the RAID group name “RG # 0” has not been registered. Again, error information is displayed and you are prompted to reenter the command line.

  Next, as shown in the state 1-4 in FIG. 5, it is assumed that the RAID group name is corrected to the registered “RG # 1”, but the next option name “encryption” is determined to be inconsistent. For example, it is assumed that the encryption function for the created logical volume cannot be validated because the encryption function for the entire storage system is invalid. Again, error information is displayed and you are prompted to reenter the command line.

  Next, as shown in state 1-5, it is assumed that the last option name “exc” is determined to be inconsistent although the encryption function of the logical volume has been corrected to disable. For example, it is assumed that the accelerated cache function for the created logical volume cannot be enabled because the accelerated cache function for the entire storage system is disabled. Again, error information is displayed and you are prompted to reenter the command line.

  Then, as shown in state 1-6, when the logical volume acceleration cache function is modified to disable, the command execution conditions for all options are satisfied, and processing based on the command line is executed. . When the process is completed normally, a command prompt is displayed, and a state in which a new command line can be input is entered.

  As shown in the examples of FIGS. 4 and 5 above, when it is determined that there is an input error for a plurality of options on the command line and there is no consistency, the user sets the command line from the top by the number of those options. You must re-enter. For this reason, there is a problem that it takes a lot of labor for the input work. Also, when it is determined that a certain option is input incorrectly, it is necessary to re-input from the beginning of the command line even if the previous option is correctly input. For this reason, it is necessary to repeatedly input the same character string, resulting in low work efficiency.

  Further, in the consistency check for each option, a lot of information related to the option is collected and referred to. The collected information may include information (configuration information) related to the logical operation target as described above and information (hardware information) related to the physical operation target. For example, in the consistency check for the option in which the volume name of the logical volume is specified, the volume names for all created logical volumes are collected. As described above, since a large amount of configuration information and hardware information is collected in the consistency check, the processing time becomes long. If the command line includes multiple options, the amount of information collected will be even greater and the processing time will be longer.

  As illustrated in FIGS. 4 and 5, in the conventional CLI, the consistency check is not started unless the input of the command line is completed by pressing the Enter key. For this reason, it takes a long time to start processing based on the input command line. When there is an erroneous input for a plurality of options as in the examples of FIGS. 4 and 5, the time until the process based on the command line is started further increases.

  Also, when it is determined that a certain option is erroneously input, information about the same option is collected again after the command line is re-input even if the previous option is correctly input. For this reason, there are many cases where exactly the same information collection is repeated if there is an erroneous input of an option, and there is a problem that processing contents are useless and inefficient.

In the second embodiment, the CMs 100 and 100a have a processing function for solving the above problems.
FIG. 6 is a block diagram illustrating a configuration example of processing functions included in the CM. In the following description, the CM 100 will be described, and the description of the CM 100a will be omitted. The CM 100a can execute the same processing as the CM 100.

  The CM 100 includes a management information storage unit 110, a configuration information storage unit 120, a hardware (H / W) information storage unit 130, a command input processing unit 140, a device information change processing unit 150, and an access control unit 160. The management information storage unit 110, the configuration information storage unit 120, and the hardware information storage unit 130 are realized as a storage area of the RAM 102 or the SSD 103, for example. The processing of the command input processing unit 140, the device information change processing unit 150, and the access control unit 160 is realized by the processor 101 executing a predetermined program. This program is stored in the SSD 103, for example.

  The management information storage unit 110 stores various management information necessary for processing of the command input processing unit 140 such as a list of command names and a list of option names. The configuration information storage unit 120 stores configuration information that is information about logical operation targets such as logical volumes and RAID groups. The hardware information storage unit 130 stores hardware information that is information regarding hardware elements mounted on or connected to the CM 100.

  The command input processing unit 140 displays a CLI screen on the management terminal 220 and receives a character string input to the CLI screen. The command input processing unit 140 analyzes the received character string, determines the process instructed from the management terminal 220 based on the analysis result, and requests the apparatus information change processing unit 150 to execute the process. Further, when analyzing the received character string, the command input processing unit 140 checks the consistency of the input option based on information collected from the configuration information storage unit 120 and the hardware information storage unit 130.

  The device information change processing unit 150 executes the process requested by the command input processing unit 140. The requested processing is mainly processing for changing part of the configuration information and hardware information.

  The access control unit 160 executes access control for the logical volume in response to a request from the host device 210 while referring to the configuration information storage unit 120 and the hardware information storage unit 130. For example, when the access control unit 160 secures a cache area in the RAM 102 and receives a write request for a logical volume from the host device 210, the access control unit 160 writes the write data into the cache area and responds to the host device 210. The access control unit 160 writes back the write data written in the cache area to a predetermined area in the DE 200 at an asynchronous timing thereafter.

  FIG. 7 is a diagram illustrating an example of information stored in the configuration information storage unit. The configuration information storage unit 120 includes, for example, volume management tables 121a, 121b, 121c, ..., RAID group management tables 122a, 122b, 122c, ..., storage pool management tables 123a, 123b, 123c, ... , Copy session management tables 124a, 124b, 124c,..., Host group management tables 125a, 125b, 125c,..., And port group management tables 126a, 126b, 126c,.

  The volume management tables 121a, 121b, 121c,... Are tables created for each logical volume. In each table, for example, a logical volume name (Friendly Name), capacity, type, creation destination RAID group name, and valid / invalid information such as compression and encryption are registered.

  The RAID group management tables 122a, 122b, 122c,... Are tables created for each RAID group. A RAID group refers to a group of disks whose writing is controlled at a specific RAID level. In each table, a RAID group name, an ID of a disk constituting the RAID group, a RAID level, pool information indicating which storage pool belongs, and the like are registered.

  The storage pool management tables 123a, 123b, 123c,... Are tables created for each storage pool. A storage pool is a physical storage area in which a logical volume can be set, and is composed of one or more RAID groups. In each table, for example, a storage pool name, a group name of a RAID group to be configured, a used amount, an unused amount, power saving setting (ECO) information, and the like are registered.

  The copy session management tables 124a, 124b, 124c,... Are tables created for each copy session. In each table, for example, the volume name of the copy source logical volume, the volume name of the copy destination logical volume, mode information indicating the type of copy processing, status information indicating the status of copy processing, and the like are registered.

  The host group management tables 125a, 125b, 125c,... Are tables created for each host group. In each table, for example, identification information of host devices belonging to a host group, a volume name of an access destination logical volume, a port name of a communication port used for access, and the like are registered.

  The port group management tables 126a, 126b, 126c,... Are tables created for each port group. In each table, physical port and network device identification information used for communication with the host device, status information of each physical port and network device, and the like are registered.

  FIG. 8 is a diagram illustrating an example of information stored in the hardware information storage unit. The hardware information storage unit 130 includes, for example, disk management tables 131a, 131b, 131c, ..., CM management tables 132a, 132b, 132c, ..., and power management tables 133a, 133b, 133c, ... be registered.

  The disk management tables 131a, 131b, 131c,... Are created for each DE connected to the storage system. In each table, for example, information indicating the ID of the disk mounted in the DE, the capacity, performance, and status of each disk is registered.

  CM management tables 132a, 132b, 132c,... Are created for each CM included in the storage system. In each table, CM identification information, identification information of a device mounted on the CM, CM status information, and identification information of a power supply unit that supplies power to the CM are registered.

  The power management tables 133a, 133b, 133c,... Are created for each power supply unit included in the storage system. In each table, power unit identification information, suppliable power, and status information are registered.

Next, an example of information stored in the management information storage unit 110 will be described with reference to FIGS. 9 and 10.
FIG. 9 is a diagram illustrating a configuration example of a command list. A command list 111 illustrated in FIG. 9 is stored in the management information storage unit 110.

  In the command list 111, a list of command names that can be accepted by the CM 100 is registered in advance. Further, each command name is registered in advance in association with an information collection flag. The information collection flag is flag information indicating whether or not information collection for checking the consistency of options on the command line including the corresponding command name is necessary. The information collection flag is set to on when information collection is necessary, and is set to off when information collection is not necessary.

  Some command names registered in the command list 111 do not require information collection for consistency check. For example, in the case of a command for displaying the overall status of a device, such as the command name “show status”, there is no need for a consistency check. Further, for example, even when the validity of an argument can be implemented only by a static check, there is no need for a consistency check. An example of such a command name is “show volume” that displays information about the logical volume. In "show volume", selectable from "table" to display in table format, "detail" to display detailed information, and "list" to display in list format as configurable arguments for option name "output" Input. As described above, “show volume” has only a function of selecting from a predetermined display format, and is thus irrelevant to configuration information and hardware information, and there is no need for a consistency check.

  By associating an information collection flag with a command name in the command list 111, the command input processing unit 140 determines whether the command name needs to be collected for consistency check or not, and according to the determination result The process can be executed. As a result, the processing of the command input processing unit 140 can be made efficient.

  FIG. 10 is a diagram illustrating a configuration example of an option list. The option lists 112a, 112b, 112c,... Shown in FIG. 10 are stored in the management information storage unit 110. The option lists 112a, 112b, 112c,... Are associated with individual command names registered in the command list 111. Accordingly, as many option lists as the command names registered in the command list 111 are stored in the management information storage unit 110.

  In each option list, a list of option names that can be described following the corresponding command name on the command line is registered in advance. Further, each option name is associated with a specified flag, an essential option flag, collection target information, a collected flag, and an inquiry flag.

  The designated flag is flag information indicating whether or not the corresponding option has been designated on the command line. The designated flag is set to off indicating unspecified at the start of command line input, and is set to on when designated.

  The mandatory option flag is flag information indicating whether or not the corresponding option name is an option name of a mandatory option that must be specified following the corresponding command name. The mandatory option flag is set in advance when it is a mandatory option, and is turned off when it is not a mandatory option.

  The collection target information indicates information to be collected for the consistency check for the corresponding option name. As the collection target information, information stored in the configuration information storage unit 120 or the hardware information storage unit 130 is designated.

  For example, in the command name “create volume” instructing creation of the logical volume, the volume name (Friendly Name) of the logical volume is specified by the option name “name”. The conditions that the friendly name should satisfy are, for example, (1) 32 characters or less, (2) a unique name, and (3) not the same name as a specific volume (for example, System Volume) in the device. There is a condition.

  Among these, the conditions (1) and (3) are static conditions, and can be checked without referring to the configuration information storage unit 120 and the hardware information storage unit 130. However, in order to check whether the condition (2) is satisfied, a list of volume names (Volume Friendly Name List) of all other created logical volumes is required as the collection target information. Specifically, volume names are collected from all the set volume management tables 121a, 121b, 121c,. Then, it is checked whether or not a volume name that overlaps with the volume name specified as the argument of the option name “name” has been registered.

  In the command name “create volume”, the size of the logical volume is specified by the option name “size”. For this option name “size”, the free capacity list, the total capacity of the defined volumes, and the maximum pool capacity are specified as collection target information for determining whether a logical volume of the size specified as an argument can be set. . The free capacity list is a list of free capacity in each storage pool to which a logical volume can be set, and is collected from the storage pool management tables 123a, 123b, 123c,. The total capacity of defined volumes indicates the total capacity of logical volumes already defined in a configurable storage pool, and is collected from the volume management tables 121a, 121b, 121c,. The maximum pool capacity indicates the total capacity of the settable storage pools, and is collected from the storage pool management tables 123a, 123b, 123c,.

  The collected flag is flag information indicating whether or not all information registered in the collection target information item has been collected. The collected flag is set to OFF indicating no collection at the start of command line input, and is set to ON when collection has been completed.

  The inquiry flag is flag information indicating whether or not the command analysis unit 142 has made an inquiry to the information collection unit 143 as to whether information collection has been completed. The inquiry flag is set to OFF indicating that no inquiry is made at the start of command line input. When an inquiry is made, the inquiry flag is set to ON until the collection of the corresponding information is completed. When the inquiry flag is set to ON when the input of the corresponding option name and argument is confirmed, information necessary for the consistency check is preferentially collected for this option name.

  By the way, in each option list, option names are registered in descending order of priority. The priority indicates the level of necessity specified on the command line. Option names that must be specified are registered at the top of the option list, and option names that do not necessarily have to be specified are registered at the bottom of the option list.

  As will be described later, when collecting information for consistency check, option names are selected in order from the top of the option list, and collection target information corresponding to the selected option names is collected. As a result, the information that is necessary for the consistency check is collected earlier for the option that has a higher necessity to be specified. As a result, the probability of waiting for information collection is reduced, and the time required for information collection is shortened.

Next, details of the processing of the CM 100 according to the command input will be described.
First, FIG. 11 is a block diagram illustrating an internal configuration example of the command input processing unit. The command input processing unit 140 includes a processing continuation determination unit 141, a command analysis unit 142, and an information collection unit 143. The command analysis unit 142 includes an analysis unit 142a and a verification unit 142b.

  The function of the command receiving unit 12 in FIG. 1 is realized by the analyzing unit 142a. Further, the information collecting unit 143 implements the function of the information collecting unit 13 in FIG. Further, the function of the processing execution unit 14 of FIG. 1 is realized by the verification unit 142b and the apparatus information change processing unit 150 of FIG.

The processing continuation determination unit 141 monitors the command input state by the user, and interrupts the entire processing when a specific condition is satisfied.
The command analysis unit 142 is a processing block that analyzes an input character string and determines whether processing according to the result can be executed. The analysis unit 142a of the command analysis unit 142 performs an analysis process every time a character is input, and detects input of a command name, an option name, and an argument. When the input command name is confirmed, the analysis unit 142a requests the information collection unit 143 to collect information for consistency check. In addition, the analysis unit 142a performs a consistency check using the information collected by the information collection unit 143.

The information collection unit 143 collects information necessary for the consistency check from the configuration information storage unit 120 and the hardware information storage unit 130.
Hereinafter, the processing of these units will be described with reference to flowcharts. In the following processing, a command name confirmation flag, an option name confirmation flag, and a command executable flag are used as flag information for control. Such flag information is temporarily stored in the RAM 102.

FIG. 12 is a flowchart illustrating a processing example of the processing continuation determination unit. Note that the process of FIG. 12 is repeated at regular intervals.
[Step S11] The processing continuation determination unit 141 determines whether a predetermined time has elapsed since the last character input. The character input here includes an operation of pressing the Space key. If the predetermined time has elapsed, the process of step S13 is executed. If the predetermined time has not elapsed, the process of step S12 is executed.

  [Step S12] The processing continuation determining unit 141 determines whether there is a key input for deleting a character, specifically, whether the Back Space key or the Delete key is pressed. If any of these key inputs has occurred, the process of step S13 is executed. If neither of these inputs is received, the process is terminated, and the process of FIG. 12 is executed again after a predetermined time.

[Step S13] The processing continuation determination unit 141 sets the command name determination flag to OFF.
[Step S14] The processing continuation determination unit 141 sets the option name determination flag to OFF.

[Step S15] The processing continuation determination unit 141 sets the command executable flag to OFF.
[Step S16] The processing continuation determination unit 141 clears the information collected by the information collection unit 143.

Note that the processing order of steps S13 to S16 can be changed.
[Step S17] The processing continuation determining unit 141 deletes the character string input after the command prompt, displays the command prompt again, and returns to a state where it can accept character input.

FIG. 13 is a flowchart illustrating a processing example of the command analysis unit.
[Step S21] The analysis unit 142a of the command analysis unit 142 monitors the key input, and executes the process of step S22 when the key input is received. Here, the process of step S22 is executed when any one of input of one character, pressing of the Space key, or pressing of the Enter key is detected.

  [Step S22] The analysis unit 142a determines whether the command name determination flag is on. If it is on, the process of step S24 is executed. If it is off, the process of step S23 is executed.

[Step S23] The analysis unit 142a executes a command name determination process for determining the input command name.
[Step S24] The analysis unit 142a determines whether the option name determination flag is on. If it is on, the process of step S26 is executed. If it is off, the process of step S25 is executed.

[Step S25] The analysis unit 142a executes an option name determination process for determining the input option name.
[Step S26] The command analysis unit 142 determines an input value as an argument, and executes an input value determination process for executing a process corresponding to the value.

[Step S27] The analysis unit 142a determines whether the command execution flag is on. If it is on, step S28 is executed, and if it is off, the process is terminated.
[Step S28] The device information change processing unit 150 executes an information change process for changing the setting values of the configuration information and the hardware information in accordance with the contents of the input command line.

FIG. 14 is a flowchart illustrating an example of command name determination processing. The process of FIG. 14 corresponds to the process of step S23 of FIG.
[Step S23a] The analysis unit 142a searches the command list 111 for a command name that matches the input character string. The input character string here is a character string obtained by adding the character input in step S21 in FIG. 13 to the character string already input after the command prompt.

  [Step S23b] The analysis unit 142a determines whether or not a command name that matches the input character string in the forward direction exists in the command list 111. If it exists, the process of step S23d is executed, and if it does not exist, the process of step S23c is executed.

  [Step S23c] The analysis unit 142a interrupts the command line input reception, and displays an error message indicating that the command name is incorrect on the line next to the line that has received the input on the CLI screen. And the analysis part 142a displays a command prompt again, and returns to the state which can accept character input.

  [Step S23d] The analysis unit 142a determines whether a command name that matches the input character string is uniquely determined. If it is determined uniquely, that is, if there is only one command name that matches the input character string, the process of step S23f is executed. On the other hand, if it is not uniquely determined, that is, if there are a plurality of command names that match the input character string, the process of step S23e is executed.

[Step S23e] The analysis unit 142a additionally displays the character input in step S21 next to the input character string.
[Step S23f] The analysis unit 142a sets the command name determination flag to ON. As a result, when one character is next input, the option name determination process in step S25 of FIG. 13 is executed.

  [Step S23g] The analysis unit 142a notifies the information collection unit 143 of a uniquely defined command name, that is, a confirmed command name, and requests to start the information collection processing corresponding to the command name.

[Step S23h] The analysis unit 142a displays the confirmed command name on the CLI screen.
Here, FIG. 15 is a diagram illustrating an example of a command name input operation. A specific example of the processing of FIG. 14 will be described with reference to FIG.

  In the state 2-1, "create" is input after the command prompt, and a space is input. Assume that the character “v” is input from this state. At this time, it is assumed in step S23d of FIG. 14 that it is determined that the command name that matches the input character string is not uniquely determined. In this case, as shown in the state 2-2, the character “v” is additionally displayed on the CLI screen, and the acceptance of the character input is continued.

  Next, it is assumed that the character “o” is input, and the command name that matches the input character string is determined as “create volume” in step S23d. In this case, as shown in state 2-3, the confirmed command name “create volume” is displayed on the CLI screen, and an input of an option name is awaited. Thereby, the input operation of the command name by the user is assisted.

  Also, when the command name is confirmed to be “create volume” before the entire command name “create volume” is entered, information collection for consistency check on the options following “create volume” is started. The Thus, by starting the information collection at an early stage, it is possible to shorten the time until the entire processing corresponding to the command is completed.

FIG. 16 is a flowchart illustrating an example of option name determination processing. The process of FIG. 16 corresponds to the process of step S25 of FIG.
[Step S25a] The analysis unit 142a determines whether the Enter key has been pressed. If pressed, the process of step S25b is executed, and if there is another input operation, the process of step S25c is executed.

[Step S25b] The analysis unit 142a executes a command execution determination process for verifying whether all the required options corresponding to the confirmed command name have been input.
[Step S25c] The analysis unit 142a searches the option list corresponding to the confirmed command name from the option lists 112a, 112b, 112c,. The input character string here is a character string obtained by adding the character input in step S21 in FIG. 13 to the character string input after the confirmed command name or optional argument. In addition, the option list referred to in subsequent steps S25d to S25n is the option list that is the search target in step S25.

  [Step S25d] The analysis unit 142a determines whether an option name that matches the input character string is present in the option list. If it exists, the process of step S25g is executed, and if it does not exist, the process of step S25e is executed.

  [Step S <b> 25 e] The analysis unit 142 a suspends command line input reception, and displays an error message indicating that the option name is incorrect on the line next to the line that has been input on the CLI screen.

  [Step S25f] The analysis unit 142a displays, on the next line of the error message, the same command line character string as that immediately before the input of the option name (the character string immediately before accepting the key input in step S21 in FIG. 13). Returns to the state where it can accept character input.

  [Step S25g] The analysis unit 142a determines whether an option name that matches the input character string is uniquely determined. If it is uniquely determined, that is, if there is only one option name that matches the input character string, the process of step S25i is executed. On the other hand, if it is not uniquely determined, that is, there are a plurality of option names that match the input character string, the process of step S25h is executed.

[Step S25h] The analysis unit 142a additionally displays the character input in step S21 next to the input character string.
[Step S25i] The analysis unit 142a determines whether the option name uniquely determined, that is, the determined option name is an unspecified option name on the current command line. In this process, in the option list, when the option designation flag corresponding to the confirmed option name is OFF, it is determined as unspecified, and when it is ON, it is determined as specified. If it is an unspecified option name, the process of step S25l is executed, and if it is a specified option name, the process of step S25j is executed.

  [Step S <b> 25 j] The analysis unit 142 a suspends command line input reception, and displays an error message indicating that the option name is duplicated on the line next to the line that has been accepted on the CLI screen. To do.

  [Step S25k] The analysis unit 142a displays, on the next line of the error message, the same command line character string as that immediately before the input of the option name (the character string immediately before accepting the key input in step S21 in FIG. 13). Returns to the state where it can accept character input.

  [Step S251] The analysis unit 142a sets the option name determination flag to ON. As a result, when one character is input next, the input value confirmation processing in step S26 of FIG. 13 is executed.

[Step S25m] The analysis unit 142a sets on a designated flag corresponding to the confirmed option name among the option names registered in the option list.
[Step S25n] The analysis unit 142a displays the determined option name on the CLI screen.

Note that the processing order of steps S251 to S25n can be changed.
Here, FIG. 17 is a diagram illustrating an example of an option name input operation. A specific example of the process of FIG. 16 will be described with reference to FIG.

  In state 3-1, after the command name “create volume”, the option name “name” and its argument “olun # 01” are specified, and then the input of the option name is continued, and the character string “na” Has already been entered. When the character “m” is input from this state, it is assumed that the input option name is determined to be “name” in step S25g of FIG. In this case, before the entire option name “name” is input, the input option name is confirmed and the user's input operation is assisted.

  However, in step S25i, it is determined that the option name “name” has already been specified, and an error message is displayed on the next line as shown in state 3-2. Then, on the next line, the command line returns immediately before the input of the option name “name”. As described above, an erroneous input of an option name is automatically determined and notified to the user, and the user can resume the input operation from a state immediately before the input of the erroneously input option name. Therefore, the convenience of the user can be improved and the work efficiency can be improved.

18 and 19 are flowcharts showing an example of the input value determination process. The processing in FIGS. 18 and 19 corresponds to the processing in step S26 in FIG.
[Step S26a] The analysis unit 142a determines whether the Enter key or the Space key is pressed. When the Enter key or the Space key is pressed, the process of step S26d is executed, and when there is another input operation, the process of step S26b is executed.

  [Step S <b> 26 b] The analysis unit 142 a temporarily records the input characters in the RAM 102. If there is a character already recorded, the entered character is added to it and recorded. The temporarily recorded character or character string is a character or character string input after the option name.

  [Step S26c] The analysis unit 142a additionally displays the character input in step S21 next to the input character string on the CLI screen. Thereby, the processing of FIGS. 18 and 19 is completed.

  [Step S26d] The analysis unit 142a determines whether the information collection flag corresponding to the confirmed command name is on in the command list 111. If it is on, the process of step S26f is executed. If it is off, the process of step S26e is executed.

  [Step S26e] When the information collection flag corresponding to the confirmed command name is OFF, it is not necessary to collect information for the consistency check on this command name. Therefore, the verification unit 142b of the command analysis unit 142 checks the validity of the input option name and argument without using the information collection unit 143.

[Step S26f] The verification unit 142b inquires of the information collection unit 143 whether information necessary for the consistency check for the confirmed option name has been collected.
At this time, the information collection unit 143 refers to the option list corresponding to the confirmed command name and determines whether the collected flag corresponding to the confirmed option name is on or off. When the collected flag is on, the information collection unit 143 notifies the verification unit 142b that necessary information for the option name to be inquired has been collected. On the other hand, when the collected flag is off, the information collecting unit 143 notifies the verification unit 142b that necessary information for the option name to be queried has not been collected.

  [Step S26g] The verification unit 142b determines whether information has been collected as a result of the inquiry. If the information has been collected, the process of step S26j is executed. If the information has not been collected, the process of step S26h is executed.

  [Step S26h] The verification unit 142b sets the inquiry flag corresponding to the confirmed option name to ON in the option list corresponding to the confirmed command name.

[Step S <b> 26 i] The verification unit 142 b performs the process of step S <b> 26 f again after delaying for a predetermined time.
[Step S26j] The verification unit 142b checks the validity of the input option name and argument based on the information collected by the information collection unit 143. In this process, the consistency between the input option name and argument and the collected information is verified.

  [Step S26k] The analysis unit 142a determines whether the input value is valid as a result of the validity check in step S26e or step S26j. If it is valid, the process of step S26o is executed, and if it is not valid, the process of step S261 is executed.

  [Step S261] The analysis unit 142a interrupts the command line input reception, and displays an error message indicating that the input option name and argument are not valid on the line next to the input line on the CLI screen. To do.

[Step S26m] The analysis unit 142a clears the character or the character string temporarily recorded in the RAM 102.
[Step S26n] The analysis unit 142a displays, on the next line of the error message, the same command line character string as that immediately before the input of the argument (the character string immediately before the key input is received in step S21 in FIG. 13). Returns to a state where input can be accepted.

  Note that the processing order of steps S261 and S26m or the processing order of steps S26m and S26n can be interchanged. When steps S261 to S26n are executed, the processing of FIGS.

  [Step S26o] The analysis unit 142a determines whether the Enter key is pressed in step S21. If pressed, the process of step S26s is executed, and if there is another input operation, the process of step S26p is executed.

[Step S26p] The analysis unit 142a clears the character or the character string temporarily recorded in the RAM 102.
[Step S26q] If it is determined in step S26o that the Enter key has not been pressed, the command line input has not ended. Therefore, the analysis unit 142a sets the option name confirmation flag to off. As a result, when one character is next input, the option name determination process in step S25 of FIG. 13 is executed again.

[Step S26r] The analysis unit 142a additionally displays the character input in step S21 next to the input character string on the CLI screen.
Note that the processing order of steps S26p to S26r can be changed. When the processes of steps S26p to S26r are executed, the processes of FIGS.

[Step S26s] The analysis unit 142a executes a command execution determination process for verifying whether all the required options corresponding to the confirmed command name have been input.
[Step S26t] The analysis unit 142a clears the character or the character string temporarily recorded in the RAM 102.

[Step S26u] The analysis unit 142a sets the option name determination flag to OFF.
The processing order of steps S26t and S26u can be switched. When the processes of steps S26t and S26u are executed, the processes of FIGS. 18 and 19 are terminated.

Here, FIG. 20 is a diagram illustrating an example of an argument input operation. A specific example of the processing of FIGS. 18 and 19 will be described with reference to FIG.
In the state 4-1, an argument is input following the option name “name” that specifies the volume name of the logical volume, and the character string “sampl” has already been input. When the character “e” is input from this state, since the input value of the argument is not fixed, steps S26b and S26c of FIG. 18 are executed, and the display state is as shown in state 4-2.

  Next, when the Enter key is pressed, the input value of the argument is confirmed as “Sample”. At this time, in step S26f, an inquiry is made as to whether information necessary for the validity check has been collected. If collected, a validity check is performed in step S26j. For example, volume names are collected from all volume management tables 121a, 121b, 121c,. If these pieces of information have not been collected, waiting is performed for a predetermined time in step S26i. When all are collected, it is determined whether a volume name that overlaps with “Sample” has been registered. If it has not been registered, it is determined to be valid in step S26k of FIG.

  Thereafter, the process proceeds to step S28 in FIG. 13, and processing corresponding to the contents of the input command line is executed by the device information change processing unit 150. When the processing is completed, a new command line can be input as shown in state 4-3.

  In practice, is it possible to execute processing based on the contents of the command line as shown in FIG. 21 after the end of the command line is detected by pressing the Enter key and the consistency check is performed? Processing to determine whether or not is executed.

FIG. 21 is a flowchart illustrating an example of command execution determination processing. The process in FIG. 18 corresponds to the process in step S25b in FIG. 16 and step S26s in FIG.
[Step S101] The analysis unit 142a determines whether all required options for the confirmed command name are specified in the input command line. Specifically, the analysis unit 142a refers to the option list corresponding to the confirmed command name, and determines whether there is an option name with the specified flag turned off among the option names with the mandatory option flag turned on. If there is an option name corresponding to this condition, it is determined that there is an unspecified mandatory option. When all the mandatory options are specified, the process of step S102 is executed, and when there is an unspecified mandatory option, the process of step S103 is executed.

  [Step S102] The analysis unit 142a sets a command execution flag to ON. As a result, the process proceeds from step S27 in FIG. 13 to step S28, and processing corresponding to the input command line is executed.

  [Step S103] The analysis unit 142a stops accepting input on the command line, and displays an error message indicating that an option that must be specified remains on the line next to the input accepted on the CLI screen. To do.

  [Step S104] The analysis unit 142a redisplays the input command line character string on the next line of the error message, and additionally displays a space at the end of the error line to return to a state in which character input can be accepted. To do.

  According to the processing in FIG. 21 described above, when an operation for confirming the command line is performed by the user, it is checked whether all the options that must be designated are designated following the confirmed command name. When there are unspecified options, the user can specify further options following the input contents. This prevents erroneous user input and eliminates the need for the user to input again from the beginning of the command line. Therefore, the convenience of the user can be improved and the work efficiency can be improved.

  FIG. 22 is a flowchart illustrating a processing example of the information collection unit. When the information collection unit 143 is requested to start the information collection process from the analysis unit 142a in step S23g of FIG. 14, the information collection unit 143 performs the process of FIG.

  [Step S31] The information collection unit 143 searches the option list 112a, 112b, 112c,... For an option list corresponding to the command name notified from the analysis unit 142a. Thereafter, processing is performed using the retrieved option list.

  [Step S32] The information collection unit 143 determines whether the option list includes an option name whose inquiry flag is on. If there is even one option name with the inquiry flag turned on, the process of step S34 is executed. If there is no option name with the inquiry flag turned on, the process of step S33 is executed.

[Step S33] The information collection unit 143 selects, from the option list, the first option name among the option names for which the inquiry flag is off as the processing target.
[Step S34] The information collection unit 143 selects, from the option list, the first option name among the option names for which the inquiry flag is on as the processing target.

  [Step S35] The information collection unit 143 reads the collection target information corresponding to the selected option name from the option list. The information collection unit 143 collects information necessary for the consistency check from the configuration information storage unit 120 and the hardware information storage unit 130 based on the read information. The information collection unit 143 temporarily stores the collected information in the RAM 102.

  [Step S36] The information collection unit 143 sets the collected flag corresponding to the selected option name to ON in the option list. When the inquiry flag corresponding to the selected option name is on, the information collection unit 143 sets the inquiry flag to off.

  [Step S37] The information collection unit 143 determines whether the option list includes an option name whose collected flag is off. If there is even one option name whose collected flag is off, the process of step S32 is executed again. If there is no option name for which the collected flag is off, the process ends.

  According to the processing of FIG. 22 described above, when an information collection process is requested, option names are selected in order from the top of the option list, and information corresponding to the selected option name is collected. In the option list, option names are registered in descending order of priority according to the need to be specified, so information corresponding to option names that are likely to be specified prior to the above processing is preferentially collected. Is done. Therefore, when the input of the option name and the argument is confirmed, there is a high possibility that the information necessary for the consistency check has been collected. As a result, it is possible to shorten the time until the processing corresponding to the command line is completed.

  An option name with the inquiry flag on is selected with priority over an off option name, and the corresponding information is collected. The inquiry flag is set to ON when waiting for the completion of collecting necessary information for the consistency check of the option name and argument whose input is confirmed. For this reason, when the inquiry flag is set to ON, the option name that needs to be collected immediately is preferentially selected regardless of the priority assigned to the option name in advance, and the corresponding information is collected. It can be executed early. Thereby, the waiting time until the consistency check can be executed can be shortened, and as a result, the time until the processing corresponding to the command line is completed can be shortened.

Here, FIG. 23 is a diagram illustrating an example of a command line input operation.
In the state 5-1, the input of the command name “create volume” is confirmed, and the input of the option name is awaited. At this point, the information collection unit 143 starts collecting information for a consistency check based on the option list corresponding to the command name “create volume”. This information collection is started in response to the request in step S23g of FIG.

  Information collection processing (FIG. 22) by the information collection unit 143 is executed in parallel with the following processing by the command analysis unit 142. Further, the information collection unit 143 temporarily stores the information collected for each option name in the RAM 102 (step S35 in FIG. 22).

  After this, as shown in state 5-2, it is assumed that the option name “name” for specifying the volume name of the logical volume and the character string “sample” are input, and the argument “sample” is confirmed by pressing the Space key. . The verification unit 142b of the command analysis unit 142 uses the information collected by the information collection unit 143 for the option name “name” to check the consistency of the option name “name” and the argument “sample” (step in FIG. 18). S26g).

  Here, it is assumed that the argument “sample” overlaps with the volume name of another logical volume and is determined to be invalid. At this time, an error message is displayed as shown in a state 5-3, and an input of an option name after the command name “create volume” is awaited.

  Next, it is assumed that the same option name “name” is input again and an argument “sample # 0” is input as shown in the state 5-4. Here, the information collected for the option name “name” by the information collection unit 143 remains stored in the RAM 102. Therefore, the verification unit 142b can check the consistency of the option name “name” and the argument “sample # 0” by using the held information again.

  As described above, when the input command name is determined, the information collection unit 143 performs a consistency check on each option name corresponding to the command name until the entire command line is input again. The information collection is executed once and the collected information is stored. Then, even if the option name and the argument are erroneously input and the input for the same option name is repeated, the command analysis unit 142 performs the consistency check by reusing the stored information. As described above, even when the input for the same option name is repeated, the information collection process for the option name is not repeated, so that the information collection process is made efficient. As a result, the processing load on the command input processing unit 140 can be reduced. In addition, the start timing of the consistency check for each option name can be advanced, thereby shortening the time until the processing corresponding to the command line is completed.

FIG. 24 is a flowchart illustrating an example of the information change process. The process in FIG. 24 corresponds to the process in step S28 in FIG.
[Step S28a] The analysis unit 142a notifies the content of the input command line to the device information change processing unit 150 and requests information change processing according to the content. The device information change processing unit 150 changes the setting contents of the configuration information storage unit 120 and the hardware information storage unit 130 based on the notified contents.

[Step S28b] The analysis unit 142a sets all the command executable flag, command name determination flag, and option name determination flag to ON.
[Step S28c] The analysis unit 142a clears the information collected by the information collection unit 143.

  [Step S28d] The analysis unit 142a displays a command prompt again on the line following the input command line on the CLI screen, and returns to a state in which character input can be accepted.

  Note that the processing functions of the devices (the information processing device 10 and the CMs 100 and 100a) described in the above embodiments can be realized by a computer. In that case, a program describing the processing contents of the functions that each device should have is provided, and the processing functions are realized on the computer by executing the program on the computer.
