[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a file control device support system for examining various data in a file control device.

[0002]

2. Description of the Related Art Conventionally, a file control device has been put into practical use in which a plurality of host computers access data to a plurality of magnetic disk devices. In order to debug the data in the file controller or investigate the trouble, it was necessary to examine various data in the file controller. Therefore, a terminal for support (hereinafter referred to as "support tool") is connected to the file control device to read data inside the file control device, and when necessary, correct the data.

In order to check various data inside the file control device with such a support tool, it is necessary to execute the support application program by the support tool which is a computer itself.

Conventionally, this application program is stored in a floppy disk and loaded from the floppy disk into the support tool when the support tool is used.

[0005]

Therefore, the support tool user must always keep the floppy disk containing the support application program. In this respect, when the support tool has a hard disk device, if the support application program is installed in advance on this hard disk, the support tool user must carry the support application program at all times. Can be avoided.

However, when there are a plurality of support tools, it is necessary to prepare as many support application programs as there are support tools.

In such a situation that a plurality of support application programs exist, when the support application program is revised or the control program of the file controller is revised, each support tool is updated. The version numbers of the support application programs stored on the floppy disk by the user and the support application programs installed on the hard disk drive of each support tool differ depending on the usage status of each support tool user. Fear will occur. And
If the file control device is supported by an old version of the supporting application program, it may not be possible to guarantee the normal operation of the file control device. Therefore, when the support application program is revised or the control program of the file control device is revised, all support tools that are owned by each support tool user or installed in the hard disk device of each support tool are used. It is complicated because it is necessary to manage the application program by revising it.

In view of such a conventional problem, the first object of the present invention is to solve the problems even if a plurality of terminals (support tools) are used or there are a plurality of users of the terminals (support tools). A file control device that does not need to prepare a support application program for each terminal (support tool) or each user of each terminal (support tool), and as a result, does not need to perform complicated management of a plurality of support application programs. Is to provide a support system.

When the support application program is installed in the hard disk device of the support tool, the work of transferring the support application program such as revision work from the outside to this hard disk device is performed. In some cases, due to various factors, a situation may occur in which the support application program cannot be transferred correctly. As described above, if the support application program is not properly transferred, the support tool cannot maintain the correct application program.

In view of such a problem, a second object of the present invention is to control the file control so that only a valid support application program can be transferred when the support application program is transferred to the hard disk device of the support tool. It is to provide a support system for the device.

When there are many types of support work for the file control device, a plurality of types of support application programs may be prepared for each type of support work. Therefore, even when the support application program is installed in the hard disk device of the support tool, it is difficult to specify which support application program should be installed.

In view of the above problems, a third object of the present invention is to provide a support system for a file control device capable of externally specifying a support application program to be installed in a hard disk device of a support tool. Is.

This will be described with reference to the flowcharts of FIGS. This interface command is used for reading control data described in the application program management area α of the hard disk 10 of the file controller 1 (READ DIRECTORY) or for support stored in the hard disk 10 of the file controller 1, respectively. Download the application program to the hard disk 15 of the support tool 2 (LOAD PROGRAM), delete the support application program stored in the hard disk 10 of the file control device 1 (DELETE),
A new application program for support is uploaded to the hard disk 10 of the file controller 1 (NEW), or the hard disk 10 of the file controller 1 is uploaded.
Is a command for updating the support application program stored in (CHANGE) or validating the support application program stored in the hard disk 10 of the file control device 1 (VALID). The service adapter 9 of the file control device 1 reports the end to the support tool 1 after the processing for the command is completed. [READ DIRECTORY] First, the processing for the read directory command for reading the control data written in the application program management area α of the hard disk 10 of the file control device 1 will be described with reference to the flowchart of FIG.

That is, the service adapter 9 first reads the application program management area α from the hard disk 10 (S001), and then transfers the control data stored in the read application program management area α to the support tool 2. Of (S00
2). [LOAD PROGRAM] Next, the processing for the load program command (transfer request command) for searching for the support application program stored in the hard disk 10 of the file control device 1 and transferring it to the support tool 1 will be described with reference to FIG. This will be described with reference to the flowchart.

In this process, the load program command using the extension of the program name of the support application program to be read, the program name, the version number, and the byte length as a parameter is sent from the support tool 2 to the service adapter of the file controller 1. It starts by being transferred to 9.

Then, the service adapter 9 of the file controller 1 first reads the application program management area α from the hard disk 10 (S10).
1). Next, the application program management area α
The data of the first block is extracted (S102), and it is checked whether the flag A is set in the control table a (S103). If the flag A is not set, the error command is transferred and the process is terminated. If the flag A is set, it is checked whether or not the flag B is set in the control table a (S104). Then, if the flag B is not set, the next block is processed (S111) and the processes of S102 to S104 are repeated. In this way, the flag A and the flag B are added to the control table a.
Only the support programs for which is set are searched for.

On the other hand, the flag B is set in S104.
If is set, it is checked whether the extension described in the extension area b of the block matches the parameter of the command (S105). And if not,
The next block is processed (S111), S102
The process from S105 to S105 is repeated. On the other hand, if they match, it is checked whether or not the program name described in the program name area c of the block matches the parameter of the command (S106). And if it fits,
It is checked whether the version number described in the version number area d of the block matches the parameter of the command (S10).
7). Then, if they match, it is checked whether or not the byte length described in the byte length area e of the block matches the parameter of the command (S108). Above S1
If it is determined that the parameters do not match in 06 to S108, the error command is transferred and the process is terminated.

On the other hand, if it is determined in S108 that it matches, it means that a supporting application program having the same extension, program name, version number, and byte length can be found. Therefore, the logical block of the block is searched. The address written in the address area f is read, and the support application program stored in the byte length area described in the byte length area e is read from the address position in the application storage area β (S109). For example, the support application program stored in the area (β-n) from the address X to the address Y is read.

Next, the data of the read support application program is transferred to the support tool 2 (S110). The support tool 2 having received this transfer stores the data of the support application program in the support program storage unit 17 of the hard disk 15. [RESTORE PROGRAM] Next, a restore command for deleting (DELETE), adding (NEW), updating (CHANGE), and validating (VALID) the support application program stored in the hard disk 10 of the file controller 1. The processing for the above will be described with reference to the flowcharts of FIGS. 6 to 9.

In this process, the restore program command using the extension of the program name of the support application program to be read, the program name, the version number, and the byte length as a parameter is executed by the support tool 2 for file control. It starts by being transferred to the service adapter 9 of the device 1. The parameters of the processing mode are configured by a mode table including various flags. DELETE when flag C is set
NEW mode, flag E when mode, flag D is set
Indicates that CHANGE mode is set, and flag F indicates VALID mode.

Then, the service adapter 9 of the file controller 1 first checks whether or not the flag C is set as a command parameter (S201).
If the flag C is set, the DELETE mode is set. That is, the restore program command in which the flag C is set corresponds to the delete request command.

In the DELETE mode, the service adapter 9 of the file controller 1 controls the control table a of the application program management area α of the hard disk 10.
After clearing all, report the end. After issuing the command of this processing mode, all the necessary application programs must be re-registered.

On the other hand, when it is determined in S201 that the flag C is not set, the service adapter 9 of the file control device 1 checks whether or not the flag D is set as a command parameter ( S20
3). If the flag D is set, the NEW mode is set. That is, the restore program command in which the flag D is set corresponds to the storage request command.

In this NEW mode, the file controller 1
First, the service adapter 9 of the
The application program management area α is read from (S204). Next, the data of the first block of the application program management area α is extracted (S2
05), it is checked whether or not the flag A is set in the control table a (S206). Then, if the flag A is not set, it is checked whether or not the flag B is set in the control table a (S207). Then, when the flag A or the flag B is set, the next block is set as a processing target (S211), and S205 to S20.
The process of 7 is repeated. In this way, the first block α-n in which the control table a is cleared, that is, the area next to the last area β- (n-1) in which the supporting application program is stored in the application program storage area β Find β-n.

Next, the service adapter 9 of the file control device 1 next proceeds from the end address (X) in the last area β- (n-1) in which the supporting application program is stored to the application program storage area. The length up to the terminal address (Z) in the entire β is compared with the byte length of the parameter of the command to check whether the support application program can be stored (S208). And
If the data cannot be stored, an error command is issued and the process ends.

On the other hand, if the file can be stored, the service adapter 9 of the file controller 1 receives the data of the supporting application program to be stored from the support tool 2 (S209). Next, the support application program is loaded on the hard disk 10.
Stored in the application program storage area β-n. At the same time, the flag A is set in the control table a-n of the corresponding block α-n in the application program management area α, and the extension area b-n, the program name area c-n, the version number area d-n, and the byte Long region en,
Further, control data for specifying the support application program is written in the logical block address area f-n (S210). Finally, an end report is issued and the process ends.

On the other hand, when it is determined in S203 that the flag D is not set, the service adapter 9 of the file control device 1 checks whether or not the flag E is set as a command parameter (( S21
1). When the flag E is set, CHANGE
It becomes a mode. That is, the restore program command in which the flag C is set corresponds to the change request command.

In this CHANGE mode, the service adapter 9 of the file control device 1 first reads the hard disk 1
The application program management area α is read from 0 (S212). Next, the data of the first block of the application program management area α is extracted (S
213), it is checked whether or not the flag A is set in the control table a (S214). And flag A
If is not set, the error command is transferred and the process ends, but if it is set, the extension area b of the block is
It is checked whether the extension described in (1) matches the parameter of the command (S215). If they do not match, the next block is processed (S216),
The processing of S213 to S215 is repeated.

On the other hand, if the extension matches in S215, it is checked whether or not the program name written in the program name area c of the block matches the parameter of the command (S217). If they do not match, the error command is transferred and the process ends.

On the other hand, if the program names match in S217, the address (X) described in the logical block address area f-n of the searched block α-n, and the next block α. The address (Y) described in the logical block address area f- (n + 1) of-(n + 1) is read. Then, the byte length obtained by subtracting the address (X) from the address (Y) is compared with the byte length as the parameter of the command, and stored in the storage block β-n of the application program storage area β corresponding to the lock α-n. Whether the support application program can be stored, that is, (Y-X)
It is checked whether the byte length of is longer than the byte length of the parameter of the command (S218). If the data cannot be stored, an error command is issued and the process ends.

On the other hand, if it can be stored, the service adapter 9 of the file controller 1 receives the data of the support application program to be stored from the support tool 2 (S219). Next, the support application program is stored in the application program storage area β-n of the hard disk 10. At the same time, the flag A is set in the control table a-n of the corresponding block α-n in the application program management area α, and the extension area b-n, the program name area c-n, the version number area d-n, and the byte Long region en,
And control data for specifying the support application program are written in the logical block address area f-n (S220). Finally, an end report is issued and the process ends.

On the other hand, when it is determined in S211 that the flag E is not set, the VALID mode is set.
That is, the restore program command in which the flag F is set corresponds to the validation request command.

In this VALID mode, the service adapter 9 of the file control device 1 first reads the hard disk 1
The application program management area α is read from 0 (S221). Next, the data of the first block of the application program management area α is extracted (S
222), it is checked whether or not the flag A is set in the control table a (S223). And flag A
If is not set, the error command is transferred and the process ends, but if it is set, the extension area b of the block is
It is checked whether or not the extension described in (1) matches the parameter of the command (S224). If they do not match, the next block is processed (S225),
The processing from S222 to S224 is repeated.

On the other hand, if the extension matches in S224, it is checked whether the program name written in the program name area c of the block matches the parameter of the command (S226). Then, if they match, it is checked whether the version number described in the version number area d of the block matches the parameter of the command (S
227). Then, if they match, it is checked whether or not the byte length described in the byte length area e of the block matches the parameter of the command (S228). If it is determined in S226 to S228 that the parameters do not match, the error command is transferred and the process ends.

On the other hand, if it is determined to be correct in S228, the flag B is set in the control table a-n of the found block α-n (S229) and the end report is given. <Support Procedure> Next, a procedure of support work by the support system of the file controller according to the present embodiment configured as described above will be described.

When it is necessary to perform support work for the file control device 1, the support tool user connects the support tool 2 to the file control device 1 via the RS232C interface. Then, using the keyboard 6, enter "READ DIRECTORY". Then, the interface command issuing unit 19 issues a read directory command to the file control device 1. In response to the read directory command, the service adapter 9 of the file controller 1 sends all the data in the application program management area α of the hard disk 10 to the support tool 2. These data are
It is displayed on the display device 5 by the support tool 2. The support tool user can look at this data display, identify the support application program necessary for performing the support work to be performed, and
The control data of the supporting application program is set as a parameter, and "LOAD PROGRAM" is input using the keyboard 6. Then, the interface command issuing unit 19 issues a load program command in which necessary parameters are set to the file control device 1. In response to the load program command, the service adapter 9 of the file controller 1 reads the support application program specified by the parameter from the application program storage area β of the hard disk 10 and sends it to the support tool 2. The support tool 2 installs this support application program in the support program storage section 17 of the hard disk 15. After that, the support application program is executed by the support program execution unit 21 of the CPU 18.
Then, the support work for the file control device 1 (for example, debugging, failure investigation, collation of various data in the file control device 1, etc.) is performed.

If the user of the support tool 2 wants to newly register a support application program in the hard disk 10 of the file controller 1,
After a NEW mode restore program command is issued to store the new program, a VALID mode restore program command is issued to register (make it available).

When it is desired to change the version number of the registered support application program, a restore program command in the CHANGE mode is issued and the new version of the support application program is stored in the hard disk 10 of the file controller 1. After storing, the VALID mode restore program command is issued to register this new program (make it available).

As described above, according to the support system for a file controller according to the present embodiment, regardless of whether there are a plurality of support tool users or a plurality of support tools 1 themselves, the support tool 1 is used for support. The application program is copied from the original program stored in the hard disk 10 of one file control device 1 and installed in the support tool 1 each time it is used. Therefore, even when the support application program is newly registered, discarded, or the version number is changed, only the original program stored in the hard disk 10 of the file control device 1 should be managed. Therefore, it is possible to avoid the complexity of having to manage all of the supporting application programs that exist in large numbers as in the related art.

The supporting application program stored in the hard disk 10 of the file control device 1 is newly stored or changed,
After that, the VALID mode restore program command is issued, and it becomes valid for the first time, and can be installed in the support tool 2. Therefore, the support application program which has not been correctly transferred to the hard disk 10 due to various factors is the support tool 2
It is possible to avoid the situation that it is installed in. As a result, it is possible to correctly maintain the support application program.

When the support application program is newly stored in the hard disk 10 of the file control apparatus 1, the application program stored in the hard disk 10 is deleted or changed, or the support application 2 is installed, the support application program is used. The application program for the program,
It is specified based on control data such as program name extension, version number, and byte length. Therefore, even if there are multiple support application programs,
The required support application program,
It can be easily identified.

[0063]

As described above, according to the file control device support system of the present invention, even if a plurality of terminals are used or there are a plurality of users, the use of each terminal or each terminal is prevented. It is not necessary to prepare a support program for each person, and as a result, it is not necessary to perform complicated management of a plurality of support programs.
