It includes a used temporary storage area, a connection unit 23 including a USB interface and a serial interface, and a communication unit 24 including a LAN (Local Area Network) connector that realizes communication with other devices.

  The storage unit 21 stores a driver program (hereinafter referred to as a driver) 2P corresponding to the failure recovery support apparatus 1. The control unit 20 reads out and executes the driver 2P from the storage unit 21, thereby executing processing based on the control statement 121 transmitted from the failure recovery support device 1 when the failure recovery support device 1 is connected by the connection unit 23. It is possible.

  In the temporary storage area, various information generated by the processing of the control unit 20 is temporarily stored. The control unit 20 reads the driver 2P from the storage unit 21 to the temporary storage area and executes it. The control unit 20 reads the control statement 121 transmitted from the failure recovery support apparatus 1 into the temporary storage area and executes it.

  The connection unit 23 includes a USB interface as described above, and realizes transmission / reception of signals not only with the failure recovery support apparatus 1 but also with an external apparatus having a USB interface. The connection unit 23 detects that an external device is connected and notifies the control unit 20 of the connection. The connection unit 23 has a function of converting a serial signal received via the USB interface into a bus signal transmitted / received between the respective components. When the failure recovery support apparatus 1 is connected, the control unit 20 receives the control statement 121 transmitted from the failure recovery support device 1 by the connection unit 23, and connects the result of executing the processing based on the received control statement 121 Transmitted by the unit 23. Further, the connection unit 23 includes a serial interface.

  The communication unit 23 implements communication with other devices using the Internet Protocol (IP).

  Next, the type of the failure recovery support apparatus 1 in Embodiment 1 will be described. FIG. 3 is an explanatory diagram illustrating a content example of the type of the failure recovery support apparatus 1 according to the first embodiment. In the explanatory diagram of FIG. 3, the correspondence between the color for identifying the failure recovery support apparatus 1 and the content of the process executed based on the control statement 121 stored in the failure recovery support apparatus 1 of each color is shown. It is shown.

  As shown in the explanatory diagram of FIG. 3, there are nine types of failure recovery support apparatuses 1 according to the first embodiment. In the content example shown in the explanatory diagram of FIG. 3, the failure recovery support apparatus 1 whose exterior member 11 is white is for “operation isolation”. The storage unit 12 of the white failure recovery support apparatus 1 stores a control statement 121 for performing a process of determining a problem to be performed by determining a problem in the server apparatus 2 in which a failure has occurred. Has been. When the control unit 20 of the server device 2 receives the control statement 121 transmitted from the white failure recovery support device 1 through the connection unit 23, the control unit 20 reads out the control statement 121 and executes the separation process. It is desirable that the worker first connects the white failure recovery support device 1 to the server device 2 where the failure has occurred.

  Further, in the content example shown in the explanatory diagram of FIG. 3, the failure recovery support apparatus 1 whose exterior member 11 is red is for “failure data automatic collection”, and the failure recovery support apparatus 1 whose exterior member 11 is blue is “ For "reboot". The failure recovery support apparatus 1 whose exterior member 11 is orange is for “forcible termination of a process corresponding to an application program and automatic collection of detailed information of the application program”. When the control unit 121 of the server device 2 receives the control statement 121 transmitted from the orange failure recovery support device 1 through the connection unit 23, the control unit 20 reads out the control statement 121 and ends the process corresponding to the application program being executed. Executes processing to automatically collect detailed information such as data, logs, and settings during application execution. In addition to the content example shown in the explanatory diagram of FIG. 3, the failure recovery support device 1 whose exterior member 11 is purple is for “kernel crash creation”, and the failure recovery support device 1 in light blue is for “device test execution” The failure recovery support device 1 that is green is for “file update”, the failure recovery support device 1 that is yellow is for “system backup creation”, and the failure recovery support device 1 that is black is “various” Server configuration automatic execution ".

  Next, processing executed when the control units 10 of the plurality of types of failure recovery support apparatuses 1 shown in the explanatory diagram of FIG. 3 are connected to the server apparatus 2 will be described below with reference to flowcharts.

  4 and 5 are flowcharts illustrating an example of a processing procedure executed when the control unit 10 of the failure recovery support apparatus 1 according to the first embodiment is connected to the server apparatus 2.

  The control unit 10 determines whether or not the connection unit 13 has detected that it is connected to the server device 2 (step S101). If the control unit 10 determines that the connection unit 13 has not detected that it is connected to the server device 2 (S101: NO), it returns the process to step S101. When the control unit 10 determines that the connection unit 13 has detected that it is connected to the server device 2 (S101: YES), the control unit 10 transmits a control signal to the display unit 14 to light the LED 141 in green (step S101). S102). Since the color to be lit at this time indicates that it is being executed, the color displayed by the LED 141 is not limited to green.

  Next, the control unit 10 reads the control statement 121 stored in the storage unit 12 (step S103), transmits the read control statement 121 to the server device 2 through the connection unit 13 (step S104), and displays the display unit 14. By transmitting the control signal, the LED 141 blinks green (step S105).

  In response to the process based on the control statement 121 transmitted by itself, the control unit 10 determines whether or not the connection unit 13 has received an end notification from the server device 2 (step S106). When it is determined that the end notification has not been received from the server device 2 (S106: NO), the control unit 10 returns the processing to step S106 and waits until it is determined that the end notification has been received.

  When it is determined that the end notification is received from the server device 2 (S106: YES), the control unit 10 determines whether the end notification indicates normal end (step S107). When the control unit 10 determines that the end notification indicates normal end (S107: YES), the control unit 10 transmits a control signal to the display unit 14 to cause the LED 141 to blink blue (step S108), and the processing is normal. The sound output unit 15 outputs a sound effect indicating the end (step S109).

  When the control unit 10 determines that the end notification indicates an abnormal end (S107: NO), the control unit 10 transmits a control signal to the display unit 14 to cause the LED 141 to blink red (step S110), thereby causing an abnormal process. The sound output unit 15 outputs a sound effect indicating the end (step S111).

  Next, the control part 10 judges whether the execution result further transmitted from the server apparatus 2 was received (step S112). When it is determined that the execution result is not received from the server device 2 (S112: NO), the control unit 10 returns the process to step S112 and waits until it is determined that the execution result is received from the server device 2.

  When it is determined that the execution result has been received from the server device 2 (S112: YES), the control unit 10 stores the received execution result in the storage unit 12 (step S113).

  Next, the control unit 10 determines whether or not the end notification indicates normal end (step S114). When it is determined that the control unit 10 indicates normal termination (S114: YES), the failure recovery support apparatus 1 to be connected next is transmitted by transmitting a control signal to the display unit 14 according to the received execution result. The LED 141 is turned on so as to indicate the color (step S115), and a blinking signal is transmitted to the failure recovery support apparatus 1 to be connected next (step S116).

  If the control unit 10 determines that the abnormal end has been indicated (S114: NO), the process proceeds to the next step S117.

  Further, the control unit 10 automatically creates a document including the contents of the execution result or creates a mail with the document attached, and notifies the created mail from the communication unit 16 by the mail function (step S117).

  Next, the control unit 10 determines whether or not the connection unit 13 has detected that it has been disconnected by being unmounted by the server device 2 (step S118). If the control unit 10 determines that the disconnection is not detected by the connection unit 13 (S118: NO), the control unit 10 returns the process to step S118 and waits until it is determined that the disconnection is detected. When the connection unit 13 detects the disconnection (S118: YES), the control unit 10 determines whether or not a turn-off signal has been received from the failure recovery support apparatus 1 connected next (step S119). When it is determined that the extinguishing signal has not been received (S119: NO), the control unit 10 returns the process to step S119 and waits until it is determined that the extinguishing signal has been received. When the control unit 10 determines that the turn-off signal has been received (S119: YES), the control unit 10 turns off the LED 141 of the display unit 14 (step S120) and ends the process.

  Note that the LED 141 of the display unit 14 in step S120 may be turned off when the connection unit 13 detects disconnection in step S118. If there is no failure recovery support apparatus 1 to be connected next, the control unit 10 turns off the LED 141 when the connection unit 13 detects disconnection in step S118.

  Regarding each processing procedure for turning on and blinking the LED 141 in the processing procedures shown in the flowcharts of FIGS. 4 and 5, for colors other than the color of the failure recovery support apparatus 1 to be connected next displayed in step S115, Of course, it is not particularly limited as to whether it is blinking or lighting.

  Further, the failure recovery support apparatus 1 having different control statements 121 depending on a plurality of types basically executes the processing procedure shown in the flowcharts of FIGS. 4 and 5, but executes different processes depending on the type of the failure recovery support apparatus 1. There is a case. Corresponding to the server apparatus 2 executing a process based on the control statement 121 that varies depending on the type, there is a process that is not necessary depending on the type of the failure recovery support apparatus 1 or that should be added.

  For example, the control unit 10 of the white failure recovery support device 1 for “operation isolation” that is recommended to be connected first to the server device 2 in which a failure has occurred is shown in the flowcharts of FIGS. 4 and 5. Suppose that all the processing procedures are executed. On the other hand, depending on the type of the failure recovery support apparatus 1, a configuration in which the color that is lit by the LED 141 may be different, or a configuration in which a process of outputting a sound effect indicating the end in step S107 is not performed. In addition, when it is not necessary to receive the execution result, there may be a type of failure recovery support apparatus 1 configured such that the processing from step S108 to step S112 is not performed.

  Further, the control unit 10 of the type of the failure recovery support apparatus 1 that is connected to the second or later, such as to be connected next to the white failure recovery support apparatus 1, is shown in the flowcharts of FIGS. 4 and 5. A function for executing a process corresponding to the blinking signal transmitted by the process of step S111 in the process procedure is required. Further, for example, in the blue failure recovery support apparatus 1 for “reboot”, the connection with the server apparatus 2 is disconnected in the middle of the processing procedure by the reboot process, and thus a process corresponding to the connection may be necessary. Further, when the controller 10 of the failure recovery support apparatus 1 of the type connected after the second is connected to the server apparatus 2, the control unit 10 sends a turn-off signal to the failure recovery support apparatus 1 that is lit in its own color. It is good also as a structure which transmits. Therefore, another example of the processing procedure executed by the control unit 10 of the failure recovery support apparatus 1 will be described next.

  6 to 8 are flowcharts illustrating an example of a processing procedure executed by the control unit 10 of the failure recovery support apparatus 1 according to the first embodiment. Of the processing procedures shown in the flowcharts of FIGS. 6 to 8, the same processing steps as those shown in the flowcharts of FIGS. 4 and 5 are denoted by the same step numbers, and detailed description thereof is omitted. .

  The control unit 10 determines whether or not a blinking signal has been received by the communication unit 16 (step S21). When it is determined that the flashing signal has not been received (S21: NO), the control unit 10 returns the process to step S21 and waits until it is determined that the flashing signal has been received. If it is detected that it is connected to the server device 2 during this period (S101: YES), the process may proceed to step S102.

  If the control unit 10 determines that the blinking signal has been received (S21: YES), the control unit 10 transmits the control signal to the display unit 14 to blink the LED 141 in blue (step S22), and the process proceeds to step S101. Note that the blinking cycle of the LED 141 in step S22 may be changed so that the blinking of the LED 141 in blue can be distinguished from the blinking in step S108 to indicate normal end.

  When the control unit 10 detects that the server device 2 is connected in step S101 (S101: YES), the control unit 10 transmits a control signal to the display unit 14 to cause the LED 141 to blink in blue. The light is turned off (step S23), and a turn-off signal for turning off the LED 141 of the failure recovery support apparatus 1 connected before is transmitted to the corresponding failure recovery support apparatus 1 (step S24). Next, the control unit 10 advances the processing to the next step S102.

  Further, the control unit 10 transmits the control statement 121 (S104), blinks the LED 141 in green to indicate that the process is being executed (S105), and then the reboot process is executed in the server device 2. Accordingly, it is determined whether or not the connection unit 13 has detected that the connection with the server device 2 has been disconnected (step S25). When the control unit 10 determines that the connection is not detected by the connection unit 13 (S25: NO), the process returns to step S25 until it is determined that the connection is detected. stand by.

  When the control unit 10 determines that the connection is disconnected by the connection unit 13 (S25: YES), the control unit 10 transmits the control signal to the display unit 14 to indicate that the connection is being disconnected, thereby turning on the LED 141. Flashes red (step S26). Note that the blinking cycle may be changed so that it can be distinguished from the blinking for indicating the abnormal end in step S110.

  Next, the control unit 10 determines whether the connection unit 13 has detected that the connection to the server device 2 has been made again (step S27). When the control unit 10 determines that the connection to the server device 2 is not detected again by the connection unit 13 (S27: NO), the control unit 10 returns the process to step S27 and determines that the connection is detected. Wait until.

  When the control unit 10 determines that the connection unit 13 has detected that it has been reconnected to the server device 2 (S27: YES), the control unit 10 causes the LED 141 to blink green by transmitting a control signal to the display unit 14 (step S27). S28) The process proceeds to the determination (S106) of whether or not the end notification is received from the server device 2 by the connection unit 13. The subsequent processing procedure is the same as the processing procedure shown in the flowcharts of FIGS.

  Of the processing procedures shown in the flowcharts of FIG. 4 and FIG. 5 and the flowcharts of FIG. 6 to FIG. 8, the processing for storing the result in step S113 is for “failure data collection” and “kernel crash creation”. In the case of the failure recovery support apparatus 1, the failure data collected and transmitted and the kernel crash created and transmitted are stored in the storage unit 12.

  Next, a flowchart of processing executed by the server apparatus 2 in response to the processing procedure of the control unit 10 of the failure recovery support apparatus 1 shown in the flowcharts of FIGS. 4 and 5 and the flowcharts of FIGS. The description will be given with reference.

  FIG. 9 is a flowchart illustrating an example of a processing procedure executed by the control unit 20 of the server device 2 according to the first embodiment. The processing procedure shown in the flowchart of FIG. 9 is realized by the control unit 20 of the server device 2 reading and executing the driver 2P stored in the storage unit 21.

  The control unit 20 determines whether or not the connection unit 23 has detected that any one of the failure recovery support apparatuses 1 has been connected (step S31). When the control unit 20 determines that the connection unit 23 has not detected that the failure recovery support apparatus 1 has been connected (S31: NO), the control unit 20 returns the process to step S31 and determines that the connection has been made by the connection unit 23. Wait until it is determined that it has been detected.

  When determining that the connection unit 23 has detected that the failure recovery support apparatus 1 has been connected (S31: YES), the control unit 20 recognizes (mounts) the connected failure recovery support apparatus 1 (step S32). . The control unit 20 receives the control statement 121 transmitted from the connected failure recovery support apparatus 1 by the connection unit 23 (step S33), reads the received control statement 121 into the temporary storage area, and performs processing based on the control statement 121 Is executed (step S34). The control unit 20 transmits an end notification indicating that the process based on the control statement 121 has been executed by the connection unit 23 (step S35), and further transmits an execution result based on the control statement 121 by the connection unit 23. (Step S36). Note that the control unit 20 of the server device 2 in the first embodiment transmits the end notification in step S35 by a signal that can identify normal end / abnormal end.

  Next, the control unit 20 disconnects by unmounting the connection with the failure recovery support apparatus 1 (step S37), and ends the process.

  In addition, the reception process of the control sentence 121 transmitted from the failure recovery support apparatus 1 in step S33 is actively performed by the control unit 20 of the server apparatus 2 from the storage unit 12 of the connected failure recovery support apparatus 1. It is good also as a structure acquired by reading 121. FIG.

  As described above, the process based on the control statement 121 acquired from the failure recovery support apparatus 1 is executed, and steps S35 and S36 are executed to determine which apparatus is connected next. The execution result or the execution result to be saved is transmitted to the failure recovery support apparatus 1. Note that the end notification and execution result transmission processing in step S35 and step S36 are not necessarily executed depending on the type of the failure recovery support apparatus 1 to be connected.

  Next, the control unit 10 of the failure recovery support apparatus 1 executes the processing procedures shown in the flowcharts of FIGS. 4 and 5 and the flowcharts of FIGS. 6 to 8, and the LED 141 is recovered from the failure to be connected next. A specific example is shown about the process turned on by the color of the assistance apparatus 1. FIG.

  FIG. 10 is an explanatory diagram showing an example of the content of the color combination of the failure recovery support apparatus 1 determined to be connected next by the processing of the control unit 10 of the failure recovery support apparatus 1 according to the first embodiment. is there. Note that the color of the content example shown in the explanatory diagram of FIG. 10 corresponds to the content of the processing shown in the explanatory diagram of FIG. Further, the content example shown in the explanatory diagram of FIG. 10 shows that the LED 141 of the display unit 14 is used when the white failure recovery support device 1 for “operation isolation” is first connected when a failure occurs in the server device 2. A specific example of the color branch to be lit is shown.

  When an operator connects the white failure recovery support apparatus 1 to the connection unit 23 of the server apparatus 2 in which a failure has occurred, the server apparatus 2 performs operation isolation processing. Further, the color of the failure recovery support apparatus 1 to be connected next is indicated by an LED 141 by the control unit 10 of the white failure recovery support apparatus 1 that has received the result of execution of the processing. At this time, the failure data should be automatically collected by referring to the end notification and the execution result by the control unit 10 of the white failure recovery support device 1 or a process corresponding to the application program executed in the server device 2 Whether to collect detailed information of the application program. When the control unit 10 of the failure recovery support apparatus 1 determines that the next failure data should be automatically collected, the display unit 14 of the white failure recovery support device 1 displays the failure recovery for “automatic failure data collection”. The LED 141 is lit in “red” corresponding to the color of the exterior member 11 of the support device 1. At this time, the LED 141 of the display unit 14 of the red failure recovery support apparatus 1 to be connected next blinks in blue.

  On the other hand, the worker removes the white failure recovery support device 1 from the server device 2 according to “red” indicated by the LED 141 of the display unit 14 of the white failure recovery support device 1, and the LED 141 of the display unit 14 is blue. It is only necessary to connect the red fault recovery support apparatus 1 blinking to the server apparatus 2. When the controller 10 of the red failure recovery support apparatus 1 that has detected that it is connected to the server device 2 transmits a light-off signal, the LED 141 of the display unit 14 of the white failure recovery support apparatus 1 is turned off. In the server device 2, failure data collection processing is performed, and the failure data collected as a result of the execution is stored in the storage unit 12 of the red failure recovery support device 1. When the controller 10 of the red failure recovery support apparatus 1 determines whether or not the occurrence of the failure is a kernel problem of the server apparatus 2, and determines that the failure is a kernel problem, the red failure recovery support apparatus In the display unit 1, the LED 141 is lit in “purple” corresponding to the color of the exterior member 11 of the failure recovery support apparatus 1 for “kernel crash creation”. At this time, the LED 141 of the display unit 14 of the purple failure recovery support apparatus 1 blinks in blue.

  On the other hand, the worker removes the red failure recovery support device 1 from the server device 2 according to “purple” indicated by the LED 141 of the display portion 14 of the red failure recovery support device 1, and the LED 141 of the display portion 14 is blue. It is only necessary to connect the purple failure recovery support apparatus 1 blinking to the server apparatus 2. Since the controller 10 of the purple failure recovery support apparatus 1 that has detected that it has been connected to the server device 2 transmits a turn-off signal, the LED 141 of the display unit 14 of the red failure recovery support apparatus 1 is turned off. In the server device 2, kernel crash creation processing is performed. At this time, since the reboot process is performed during the process, the lighting / extinguishing of the LED 141 is controlled when the control unit 10 of the purple failure recovery support apparatus 1 detects disconnection and connection. The As a result of execution of the kernel crash creation process, the created kernel crash is stored in the storage unit 12 of the purple failure recovery support apparatus 1. The controller 10 of the purple failure recovery support apparatus 1 determines that the next test should be performed, and the display unit 14 of the purple failure recovery support apparatus 1 displays the failure recovery support apparatus 1 for “execution of device test”. The LED 141 is lit in “light blue” corresponding to the color of the exterior member 11. At this time, the LED 141 of the display unit 14 of the light blue failure recovery support apparatus 1 blinks in blue.

  On the other hand, the worker removes the purple failure recovery support device 1 from the server device 2 according to “light blue” indicated by the LED 141 of the display unit 14 of the purple failure recovery support device 1, and the LED 141 of the display unit 14 is blue. The light-blue failure recovery support apparatus 1 blinking in the figure may be connected to the server apparatus 2. As a result, the server apparatus 2 automatically performs a test. The test execution result is stored in the storage unit 12 of the light blue failure recovery support apparatus 1. The control unit 10 of the light blue failure recovery support apparatus 1 turns off the LED 141 when it is detected that the connection with the server apparatus 2 has been disconnected. Therefore, the operator can recognize that a series of work is completed by confirming that the LED 141 of the display unit 14 of the light blue failure recovery support apparatus 1 is turned off. The operator removes the light blue failure recovery support device 1 from the server device 2 and ends the failure recovery operation.

  As described above, the color of the failure recovery support apparatus 1 to be connected next is displayed on the display unit 14 by the processing of the control unit 10 of the failure recovery support apparatus 1. Therefore, the operator can intuitively grasp the failure recovery support apparatus 1 to be connected next. The worker only has to follow the display on the failure recovery support apparatus 1, and even if he / she does not have a high level of knowledge and technical skill, he / she can perform an appropriate process in accordance with the situation of the failure that has occurred or the situation in the test. It can be executed later and work errors are expected to be reduced.

  Further, a blinking signal is transmitted to the failure recovery support apparatus 1 connected next, and the LED 141 of the display unit 14 of the failure recovery support apparatus 1 to be connected next flashes in blue. Therefore, it is possible to further reduce work mistakes by avoiding erroneous recognition of the color of the failure recovery support apparatus 1 to be connected next by the operator, thereby further improving the reliability of system recovery.

  In addition, after finishing the processing in each failure recovery support apparatus 1, a mail (facsimile) is transmitted. By setting the mail destination to the administrator of the system maintenance operation, the result of processing at each stage is notified to the administrator. Thereby, the administrator can quickly grasp the contents of the failure recovery work, and can determine at an early stage whether or not there is a contradiction in the execution results transmitted from the plurality of failure recovery apparatuses. Thereby, the certainty of the failure recovery work can be further increased.

  In the explanatory diagram of FIG. 10, the color of the failure recovery support apparatus 1 to be connected next is displayed in the order of “white”, “red”, “purple”, and “light blue” as described above. The branching is also shown. For example, according to the color displayed on the display unit 14 of the white failure recovery support apparatus 1, the case where the worker next connects the red failure recovery support apparatus 1 to the server device 2 is also shown. In this case, when the controller 10 of the red failure recovery support apparatus 1 determines that the problem is not a kernel problem, the display unit 14 of the red failure recovery support apparatus 1 corresponds to the failure recovery support apparatus 1 for “reboot”. The LED 141 is lit in “blue”. Accordingly, when the blue failure recovery support apparatus 1 is connected to the server apparatus 2 by an operator, the display unit 14 of the blue failure recovery support apparatus 1 performs “apparatus test” after the processing is completed in the server apparatus 2. The LED 141 is lit in “light blue” corresponding to the failure recovery support apparatus 1.

  As another example, the control unit 10 of the white failure recovery support apparatus 1 that is first connected to the server apparatus 2 performs a process corresponding to the application program being executed on the server apparatus 2 according to the end notification and the execution result. When it is determined that the detailed information of the application program should be collected after termination, the display unit 14 of the white failure recovery support apparatus 1 displays “forcibly termination of the process corresponding to the application program, automatic collection of detailed information of the application program” The LED 141 is lit in “orange” corresponding to the failure recovery support apparatus 1 for “.” When the orange failure recovery support apparatus 1 is connected to the server apparatus 2 by an operator according to this, after the processing is completed in the server apparatus 2, the display unit 14 of the orange failure recovery support apparatus 1 performs “failure data automatic collection”. The LED 141 is turned on in “red” corresponding to the failure recovery support apparatus 1 for use. Further, when the red fault recovery support apparatus 1 is connected to the server apparatus 2 by the operator according to this, after the fault data automatic collection process is executed, the display unit 14 of the red fault recovery support apparatus 1 displays “reboot” The LED 141 is turned on in “blue” corresponding to the failure recovery support apparatus 1 for “”, or the LED 141 is turned on in “purple” corresponding to the failure recovery support apparatus 1 for “kernel crash creation”. When the blue LED 141 is turned on and the operator connects the blue failure recovery support apparatus 1 to the server apparatus 2 according to this, after rebooting, the display unit 14 of the blue failure recovery support apparatus 1 displays “ The LED 141 is lit in “light blue” corresponding to the failure recovery support device 1 for “device test execution”. When the purple LED 141 is lit on the display unit 14 of the red fault recovery support apparatus 1 and the purple fault recovery support apparatus 1 is connected to the server apparatus 2 by the worker according to this, the kernel crash creation processing is executed. Thereafter, the LED 141 is lit in “light blue” corresponding to the failure recovery support device 1 for “device test execution” on the display unit 14 of the purple failure recovery support device 1.

  The failure recovery support device 1 can be used not only for the server device 2 in which a failure has occurred, but also when dealing with a problem before the failure or when performing a device test before operation. FIG. 11 is an explanatory diagram illustrating an example of the content of the color combination of the failure recovery support apparatus 1 determined to be connected next by the processing of the control unit 10 of the failure recovery support apparatus 1 according to the first embodiment. is there. Note that the color of the content example shown in the explanatory diagram of FIG. 11 corresponds to the content of the processing shown in the explanatory diagram of FIG.

  In the content example shown in the explanatory diagram of FIG. 11A, an example in the case of performing a device test in the server device 2 is shown. In this case, the light blue failure recovery support apparatus 1 for “execution of apparatus test” is first connected, and the server apparatus 2 can execute the process of the apparatus test. In this case, the display unit 14 of the light blue failure recovery support apparatus 1 does not display the color of the failure recovery support apparatus 1 to be connected next.

  The content example shown in the explanatory diagram of FIG. 11B shows an example of branching when it is desired to deal with a problem before a failure in the server device 2 and update a file such as an upgrade. In this case, the worker first connects the yellow failure recovery support apparatus 1 for “system backup creation”. When the yellow failure recovery support apparatus 1 is connected to the server apparatus 2, after the system backup creation process is executed on the server apparatus 2, the display unit 14 of the yellow failure recovery support apparatus 1 should be connected next. The LED 141 is lit in “green” corresponding to the failure recovery support apparatus 1 for “file update”. Following this, after the operator connects the green failure recovery support apparatus 1 to the server apparatus 2 and executes the file update, the LED 141 is lit in “blue” corresponding to the failure recovery support apparatus 1 for “reboot”. Alternatively, the LED 141 is controlled so as to be recognized as “black” corresponding to the failure recovery support apparatus 1 for “various server setting automatic execution”. When the blue LED 141 is lit and the operator connects the blue failure recovery support apparatus 1 to the server apparatus 2 in accordance with this, after rebooting, the display unit 14 of the blue failure recovery support apparatus 1 displays “device” The LED 141 is lit in “light blue” corresponding to the failure recovery support apparatus 1 for “execution of test”. When the LED 141 is controlled so as to be recognized as black, and the black failure recovery support device 1 is connected to the server device 2 by an operator according to this, the black failure is detected after various server settings are automatically executed. On the display unit 14 of the recovery support apparatus 1, the LED 141 is lit in “blue” corresponding to the failure recovery support apparatus 1 for “reboot”. After the blue failure recovery support device 1 is connected to the server device 2 and rebooted by the operator according to this, the failure recovery support for “device test execution” is performed on the display unit 14 of the blue failure recovery support device 1. The LED 141 is lit in “light blue” corresponding to the device 1.

  The content example shown in the explanatory diagram of FIG. 11C shows an example of branching when the server setting is performed in the server device 2. In this case, the worker first connects the yellow failure recovery support apparatus 1 for “system backup creation”. When the yellow failure recovery support apparatus 1 is connected to the server apparatus 2, after the system backup creation process is executed on the server apparatus 2, the display unit 14 of the yellow failure recovery support apparatus 1 should be connected next. The LED 141 is controlled to be recognized as “black” corresponding to the failure recovery support apparatus 1 for “various server setting automatic execution”. After the black failure recovery support device 1 is connected to the server device 2 and the various server settings are automatically executed by the worker according to this, the display unit 14 of the black failure recovery support device 1 uses “reboot”. The LED 141 is lit in “blue” corresponding to the failure recovery support apparatus 1, or the LED 141 is lit in “light blue” corresponding to the failure recovery support apparatus 1 for “device test execution”. When the blue LED 141 is lit and the operator connects the blue failure recovery support apparatus 1 to the server apparatus 2 in accordance with this, after rebooting, the display unit 14 of the blue failure recovery support apparatus 1 displays “device” The LED 141 is lit in “light blue” corresponding to the failure recovery support apparatus 1 for “execution of test”.

  In this way, by preparing a plurality of types of failure recovery support apparatuses 1 according to various processes, even a worker who does not have advanced knowledge and technical skills can make various changes to the server apparatus 2. It becomes possible to execute the processing in order.

In this case, the control unit 10 is configured to output a preset control signal via the connection unit 13 when it is detected that the connection unit 13 is connected to the server device 2. When the serial interface is used, the control unit 10 can turn on the LED 141 of the display unit 14 when the control signal is output to indicate that the process has been completed. It is difficult to control the color of the LED 141 and the lighting / flashing / extinguishing according to the result.

  The failure recovery support apparatus 1 including the connection unit 13 using a serial interface outputs a control signal for causing the server apparatus 2 to execute a reboot or outputs a control signal for generating a kernel crash. As an alternative, the configuration may be added to the nine types of failure recovery support apparatuses 1 using the USB interface described in the first embodiment. In this case, when the white failure recovery support apparatus 1 is connected and the color of the apparatus to be inserted next is not lit by the display unit 14 and is not displayed at all, the failure recovery support apparatus 1 using the serial interface is displayed. It is good also as a structure utilized as an apparatus which connects with the server apparatus 2 and reboots, or an apparatus which produces a kernel crash.

  Further, by configuring the LED 141 of the display unit 14 with a three-color LED (full color LED), it is possible to display color information for identifying the failure recovery support apparatus 1 to be connected next with an easy configuration. By using the LED, the failure recovery support apparatus 1 can be reduced in size and weight. Since most colors can be reproduced by the three-color LED, it is possible to deal with many types of failure recovery support apparatuses 1.

  Note that the failure recovery support apparatus 1 according to Embodiment 1 includes the communication unit 16 and transmits / receives a blinking signal or an extinguishing signal to the other failure recovery support apparatus 1, thereby causing the LED 141 of the display unit 14 to blink or extinguish.
