DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention comprises an information processing system comprising a plurality of devices, and a service processor connected to the information processing system and having a maintenance/diagnosis function for the information processing system. Concerning the failure handling method of the system.

[Prior art and its problems]

Conventionally, in information processing systems of this type that are composed of multiple devices, when the system is started up while a certain device is out of order, that faulty device is automatically integrated into the system. There have been cases where system start-up has become impossible due to disturbances caused by the faulty device. In order to solve this problem, before starting the system, either obtain the power to the failed device and turn it off, or disconnect it using a switch on the maintenance tunnel. It is sufficient to prevent the installation of the defective device. However, since this method is performed manually, it is possible to forget this operation.

There is a drawback in that the faulty device is also incorporated into the information processing system, causing disturbances caused by the faulty device to the system.

[Problem to be solved by the invention]

In view of the above-mentioned shortcomings of the conventional system, the present invention prevents the incorporation of a faulty device into the system due to forgetting to operate it, which may occur when disconnecting it due to acquisition, thereby making it possible to start up the system reliably, and to repair the fault. The aim is to enable automatic re-incorporation into the system if the test results after completion are normal.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention uses a service processor to manage the normal/failure states of devices that constitute an information processing system, and automatically disconnects devices in a faulty state at system startup. .

In addition, after repairing a malfunctioning device, a test is performed by the service processor, and if the test result is normal, the state managed by the service processor is automatically set to normal, and the device can then be fully integrated into the system. It was designed to do so.

That is, according to the present invention, when the reference numerals of the first corresponding components are used in parentheses, there is provided an information processing system having a plurality of devices and means for controlling information, and a device connected to the information processing system. .

〔Example〕

Next, the present invention will be explained in detail.

FIG. 1 shows the structure of one embodiment of the fault handling method of the present invention (6
) is a block diagram showing the configuration. The devices shown in FIG. 1 are roughly divided into information processing systems 1 that control multiple devices and information;
0, a maintenance diagnosis interface 17゜, a service processor 20 having a maintenance diagnosis function for the information processing system, and a function for storing the program of this service processor as well as information indicating the normality/failure of the device, that is, device status information. It consists of an external storage device 31 and a 9-character display input device 32.

The information processing system 10 includes devices 11.12°1, 3,
14, a configuration control means 15 that controls the configuration of these devices 11 to 14, a failure occurrence notification function that notifies the gamma bis processor 20 of the failure when a failure occurs in this information processing system, and The maintenance diagnosis control means 16 has a failure data transfer function for transferring data to the service processor, and a startup start notification function for notifying the service processor of the start of startup of the information processing system.

When the service processor 20 is notified of the occurrence of a failure, it reads the failure data from the failure data transfer section and analyzes it.

and a failed device analysis unit 21 that changes the device status stored in the external storage device 31 to a failed state in the event of a failure.

When the information processing system 10 is started up, the configuration control unit 15 configures the device state of the external storage device 31 in response to the startup start notification.
and a device status transfer unit 22 that transfers the information to the device status transfer unit 22.

The apparatus status information 24 changes the apparatus status stored in the external storage means depending on whether the test result by the apparatus testing means is normal or not.

First, we will explain the system start-up operation, which is a well-known technique, with the above configuration.At the time of system start-up.

The configuration control unit 15 incorporates all devices except those whose power is turned off or whose disconnection is instructed by a maintenance/service switch (not shown in the figure). So as I said before.

A certain device is out of order and the device needs to be powered down or maintained.
If you forget to disconnect using the o-nel switch.

This occurred because there were cases in which the system startup operation was not performed normally due to a malfunction of the device.

Next, the operation of the main technology of the present invention will be explained with reference to the flowchart shown in FIG. Service processor 20
has information for managing the status of devices 11 to 14, and initially all devices 11 to 4 are managed as normal devices. If, for example, a failure occurs in the device 12 during system operation, the maintenance diagnosis control unit 16 notifies the service processor 20 through the maintenance diagnosis interface 17 that this failure has occurred (process 41). The failed device analysis unit 21 of the service processor 20 sends data related to the failure to the maintenance diagnosis control unit 16. Maintenance diagnosis interface 17
The information processing system 10 is read out through the process 42 and 43), and the failed device is analyzed (process 44), after which the information processing system 10 is stopped (process 45). On the other hand, if the fruiting device 12 of the analysis is determined to be faulty, the state of the device 12 among the states of the devices 11 to 14 stored in the external storage device 31 is updated as a faulty device (processing 46).

At the next system start-up 2 For example, at the time of start-up to start the next day's service (process 47), the device status transfer unit 22 of the service processor 20 responds to the start-up notification from the maintenance diagnosis control 16 (process 48). Then, the status of the system configuration devices 11 to 14 stored in the external storage device 31 is read out, and the configuration device status information is notified to the configuration control unit 15 via the maintenance diagnosis interface 17 and the maintenance diagnosis control unit 16 ( Processing 49).

The configuration control unit 15 configures the system by incorporating only the normal devices 11, 13, and 14 into the system based on the notified component device status information, and does not incorporate the failed device 12 into the system, and starts the system (processing 50). ).

Further, when the repair of the failed device 12 is completed, the operator inputs a command to the character display input device 32 and the system service processor 20 to instruct the test of the device 12 (processing 5).
1). The device testing unit 23 of the service processor 20 executes a test on the device 12 (process 52), and if the repair of the device 12 is completed correctly, the test ends normally (process 53) 1
Based on this result, the device status update unit 24 updates the device status information regarding the device 12 in the external storage device 31 from a failure state to a normal state (step 54), thereby making it possible to incorporate the device 12 into the system. If the repair of the device 12 is not completed correctly in step 53, the test will not be completed normally, the device status information regarding the device 12 will not be updated, and it will not be possible to incorporate the device 12 into the system.

〔Effect of the invention〕

As explained above, the present invention automatically tests a failed device that has been repaired simply by giving an instruction.

By configuring the system to automatically prevent the incorporation of a failed device into the system, there is an effect that system start-up can be ensured.
