[Object of the Invention] The present invention has been made in order to eliminate the drawbacks of the conventional devices as described above, and it is possible to prevent disturbances caused by devices with known failures after restarting operation, and to maintain the operation mode intended by the user. The purpose is to provide a method for automatically restarting the system.

[0005]

[Structure of the Invention] The system automatic restart method according to the present invention includes a system configuration table that stores the system configuration, a configuration change means that updates the system configuration table when the system configuration is changed, and a system configuration table that stores the system configuration. emergency system blocking means for blocking the system after failure processing for a failure is performed; and automatic restarting means that is activated when the system is blocked by the emergency system blocking means and restarts the system. The automatic restarting means restarts the system based on the result of referring to the system configuration table before the emergency system closing means shuts down the system. .

[0006]

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention. In the figure, a system configuration table 2 of a computer system 1 stores device configuration information of the system, and a system configuration table update status recording unit (hereinafter referred to as update status recording unit) 3 records whether the system configuration table 2 has been updated or not. The update status indicating the update status is recorded.

[0008] The configuration change unit 4 operates in response to failure handling or requests from users, and upon receiving the request, records in the update status recording unit 3 that the status of the device corresponding to the request has not been updated,
After updating the system configuration table 2 in accordance with the request, the unupdated state of the device recorded in the update state recording section 3 is deleted.

[0009] The emergency system blocking unit 5 is activated when a serious fault occurs in the system, and after processing the fault for the serious fault, forcibly stops the operation of the computer system 1.
The automatic system restart unit 6 is activated by the emergency system blocker 5 and restarts the computer system 1 without user intervention.

FIG. 2 is a flowchart showing the processing operation of the configuration changing unit 4 in FIG. 1, FIG. 3 is a flowchart showing the processing operation of the emergency system closing unit 5 in FIG. 5 is a flowchart showing the processing operation of the restarting unit 6. FIG.

The operation of one embodiment of the present invention will be explained using FIGS. 1 to 4.

First, when a device failure occurs during operation of the computer system 1 and failure processing is executed, or when a configuration change request is issued from a user, the configuration change unit 4 records the information of the relevant device in the update status recording unit 3. Record the status not updated (Figure 2
Step 11).

After that, the configuration change unit 4 updates the physical state of the device in question (step 12 in FIG. 2), and then updates the logical state of the device in question recorded in the system configuration table 2 (step 12 in FIG. 2). Figure 2 step 13).

When the above update processing is completed, the configuration changing unit 4 deletes the unupdated status of the corresponding device recorded in the update status recording unit 3 (step 14 in FIG. 2), and ends the process.

[0015] When a serious failure occurs in the computer system 1,
An emergency system closure request occurs and the emergency system closure unit 5
is started.

[0016] The emergency system closing unit 5 is the computer system 1
(Step 21 in Figure 3), and then block the computer system 1 (Figure 3).
Step 22).

When this blockage process is completed, the emergency system blockage section 5 starts the system automatic restart section 6 (see FIG. 3).
Step 23), the process ends.

[0018] At this time, updating the physical device status involves input/output operations and takes more time than other processes.
A serious failure may occur in the computer system 1 while the configuration change unit 4 is updating the physical device status in accordance with the configuration change request.

Therefore, the system automatic restart unit 6 started by the emergency system blocker 5 first refers to the update status recording unit 3 (step 31 in FIG. 4), and the update status recording unit 3 records the status of the device whose status has not been updated. A process of updating the system configuration table 2 is performed for the system configuration table 2 (steps 32 and 33 in FIG. 4). This eliminates the inconsistency in the configuration information caused by the state of the system configuration table 2 not being updated.

After that, the system automatic restart unit 6 retrieves the device information from the system configuration table 2 (step 3 in FIG. 4).
4) Exclude the devices that were not in the built-in state during operation before the blockage process was performed by the emergency system blockage unit 5 from the built-in devices at the time of restarting and perform the built-in process (steps 35 to 37 in FIG. 4), and then system operation is resumed (step 38 in FIG. 4).

By the processing described above, the computer system 1
If a serious failure occurs and automatic restart is performed after the computer system 1 is shut down, the configuration state of the computer system 1 can be made the same as the state before the shutdown.

In this manner, when a serious failure occurs in the computer system 1, even if the failure occurs during the configuration change of the computer system 1, the system before the emergency system blocker 5 blocks the computer system 1. By automatically restarting the system by referring to the system configuration table 2 that stores configuration information, it is possible to automatically restart devices that have been disconnected due to a failure during operation or devices that have been disconnected due to an intentional configuration change by the user. can be excluded from being included during automatic restart.

[0023] Therefore, even after automatic restart,
Since the configuration state of the computer system 1 before the blockage is maintained, it is possible to prevent disturbances caused by devices with known failures after restarting the operation, and to maintain the operation mode intended by the user.

[0024]

As explained above, according to the present invention, by restarting the system based on the result of referring to the system configuration table before the system was shut down, the known This has the effect of preventing disturbances caused by faulty devices and maintaining the operational configuration intended by the user.
