DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic system restarting method, and more particularly, to a method of taking over a system configuration state when a computer system is automatically restarted.

[0002]

2. Description of the Related Art Conventionally, in a system for automatically restarting a computer system, all devices registered in a system configuration table are to be installed, as in the case of a normal restart of the computer system. Could be used effectively.

In such a conventional automatic restarting method for a computer system, when the automatic restarting is performed, all the devices registered in the system configuration table are to be incorporated. Devices that have been disconnected due to a failure, or devices that have been disconnected due to a user's intentional configuration change are also targets for installation, and the configuration state when operation becomes possible before automatic restart is completed Therefore, there is a possibility that disturbance will occur due to the known faulty device, or that the operation mode intended by the user will not be achieved.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in order to eliminate the above-mentioned drawbacks of the prior art, and it is intended to prevent a disturbance due to a known faulty device after the restart of operation and to maintain an operation form intended by a user. The purpose is to provide a system automatic restart system that can be used.

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 one 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 an update status recording unit) 3 determines whether the system configuration table 2 has been updated. Is recorded.

The configuration changing unit 4 operates in response to a failure process or a request from a user, and when the request is accepted, records the status update of the device corresponding to the request in the update status recording unit 3.
After the system configuration table 2 is updated in accordance with the request, the status update of the device recorded in the update status recording unit 3 is deleted.

The emergency system closing unit 5 is activated by the occurrence of a serious failure in the system, and forcibly stops the operation of the computer system 1 after processing the failure for the serious failure.
The system automatic restart unit 6 is started by the emergency system closing unit 5 and executes restart of the computer system 1 without user intervention.

FIG. 2 is a flowchart showing the processing operation of the configuration changing unit 4 of FIG. 1, FIG. 3 is a flowchart showing the processing operation of the emergency system closing unit 5 of FIG. 1, and FIG. 9 is a flowchart illustrating a processing operation of a restart unit 6.

The operation of the embodiment of the present invention will be described with reference to FIGS.

First, when a device failure occurs during operation of the computer system 1 and a failure process is executed, or when a configuration change request is made by a user, the configuration change unit 4 stores the corresponding device in the update status recording unit 3. Record the status not updated (Fig. 2
Step 11).

Thereafter, the configuration changing unit 4 updates the physical state of the corresponding device (step 12 in FIG. 2), and then updates the logical state of the corresponding device recorded in the system configuration table 2 (step 12). FIG. 2 step 13).

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

When a serious failure occurs in the computer system 1,
An emergency system block request is generated and the emergency system block section 5
Is started.

The emergency system closing unit 5 is the computer system 1
Is physically separated from all the devices (step 21 in FIG. 3), and then the computer system 1 is closed (FIG. 3).
Step 22).

When the closing process is completed, the emergency system closing unit 5 starts the system automatic restart unit 6 (FIG. 3).
Step 23), the process ends.

At this time, updating of the physical device state involves input / output operations and takes longer time than other processes.
While the configuration change unit 4 is performing the physical device state update process in accordance with the configuration change request, a serious failure may occur in the computer system 1.

For this reason, the automatic system restarting section 6 started by the emergency system closing section 5 first refers to the updated state recording section 3 (step 31 in FIG. 4). Then, a process of updating the system configuration table 2 is performed (steps 32 and 33 in FIG. 4). Thereby, the inconsistency of the configuration information due to the status update of the system configuration table 2 is resolved.

Thereafter, the system automatic restart unit 6 extracts the device information from the system configuration table 2 (step 3 in FIG. 4).
4) The devices that were not in the built-in state in the operation before the closing process by the emergency system closing unit 5 was performed are excluded from the built-in devices at the time of restarting, and the mounting process is performed (FIGS. 4 steps 35 to 37). The system operation is restarted (step 38 in FIG. 4).

By the processing described above, the computer system 1
If the computer system 1 is automatically restarted after the computer system 1 is closed after a serious failure has occurred, the configuration state of the computer system 1 can be made the same as the state before the closing.

As described above, when a serious fault occurs in the computer system 1, even if the fault is being changed in the configuration of the computer system 1, the device before the emergency system closing unit 5 closes the computer system 1 By automatically restarting with reference to the system configuration table 2 storing configuration information, a device disconnected due to a failure during operation or a device disconnected due to a user's intentional configuration change Can be excluded from the integration target at the time of automatic restart.

Therefore, even after the automatic restart,
Since the configuration state of the computer system 1 before the blockage is retained, disturbance due to the known faulty device after the restart of operation can be prevented, and the operation form intended by the user can be retained.

[0024]

As described above, according to the present invention, the system is restarted on the basis of the result of referring to the system configuration table before the system was shut down, so that the known system after the restart of operation is obtained. There is an effect that disturbance due to the failure device can be prevented, and the operation form intended by the user can be maintained.
