In this way, by providing the maintenance diagnosis control unit 31 with the function of controlling the interface between each part of the computer system 3 and the service processor 1, the service processor 1 can control the interface during maintenance of the computer system 3. Since this becomes unnecessary, maintenance of the computer system 3 can be performed at high speed. In addition, other computer systems 4
, 5.6 also have the same configuration as the computer system 3.

FIG. 3 and FIG. 4 are flowcharts showing processing examples of the maintenance control execution unit 11.21. FIG. FIG. 4 shows an example of processing when maintenance such as diagnosis and reading of hardware registers is performed by commands input from the maintenance console 12.22.

Next, the operation of this embodiment will be described by taking as an example the case where the service processor 1 is the active system and the service processor 2 is the standby system.

First, with reference to FIG. 3, the operation when maintenance is performed in response to a request from the computer system will be described.

Now, for example, suppose that a failure occurs in the execution processing device 33 within the computer system 3. When the fault detection circuit 331 of the execution processing device 33 detects that a fault has occurred in the execution processing device 33, it sends a fault notification including fault type information indicating the type of fault to the maintenance diagnosis control unit 31. When the maintenance diagnosis control unit 31 receives a failure notification from the failure detection circuit 331, it determines whether the maintenance diagnosis control unit 31 itself can process the notification based on the failure type information included therein.

If the maintenance diagnosis control unit 31 determines that it can handle the problem itself, it collects the fault information and processes the fault, then reads the boat number from the boat number storage unit 36 and adds the read boat number to the fault notification. Add it to the operational service processor 1. If the maintenance diagnosis control section 31 determines that the process cannot be performed by itself, the boat number is immediately read from the boat number storage section 36, and the read boat number is added to the fault notification and sent to the service processor 1.

When the maintenance control execution unit 11 in the service processor 1 receives a fault notification with a boat number added from the computer system 3, it starts the process shown in the flowchart of FIG. The next step 102 is to receive a failure notification with a boat number added from the diagnostic control unit 31 and determine its contents.
In the computer system determination process, the boat number of the maintenance diagnosis control unit 31 accepted in step 101 is used to calculate the correspondence table 13 stored in the magnetic disk device 13.

In step 103 processing procedure, step 102
The procedure table 132 is searched based on the type of computer system 3 determined in , and the failure procedure corresponding to the type of computer system 3 is read. Next step 104
In the DGU command execution process, a procedure corresponding to the content (fault type) determined in step 101 is selected from among the fault procedures read in step 103, and DGU commands are sequentially sent to the maintenance diagnosis control unit 31 according to the selected procedure. Issue. When the maintenance diagnosis control unit 31 receives a DGU command from the maintenance control execution unit 11, it collects failure information in accordance with the DGU command.

Perform troubleshooting, etc. When the DGU command execution process in step 104 is completed, the maintenance control execution unit 11 performs the result storage process in step 105, and stores the failure information collected by the maintenance diagnosis control unit 31 in the magnetic disk device 13.

When a failure occurs in any part of the system, the correspondence table 131 and procedure table 132 are referred to and maintenance is performed in the same way as described above.

Next, the operation when maintaining the computer systems 3, 4, 5, and 6 by inputting commands from the maintenance console 12 will be explained, taking as an example the case of reading out the status of the failure detection circuit 331 of the execution processing unit 33. .

When an operator reads the status of the failure detection circuit 331 of the execution processing unit 33, the operator inputs the system name of the computer system 3 and the register name corresponding to the failure detection circuit 331 from the maintenance console 12 connected to the operational service processor 1. Enter console commands that include:

When the above-mentioned console command is input from the maintenance console 12, the maintenance control execution unit 11 in the service processor 1 interprets the input console command in the input command interpretation process of step 201. If the input console command is a request for maintenance on the computer system 3, such as a read request to hardware, the computer system determination process of step 202 is performed, and if it is determined that it does not require maintenance, then Perform other processing.

In the computer system determination process of step 202, the correspondence table 131 stored in the magnetic disk device 13 is searched based on the system name of the computer system 3 included in the console command, and the type of the computer system 3 is determined. In the process sequence continuation process of step 203, the failure procedure corresponding to the type of computer system 3 determined in step 202 is read from the procedure table 132 stored in the magnetic disk device 13. Then, from the fault procedure read in step 203, a read procedure for the fault detection circuit 331 is selected based on the register name included in the console command, and the DGU commands are sequentially maintained according to the DGU command string described in the selected procedure. Issued to the diagnostic control unit 31. The maintenance diagnosis control section 31 reads the state of the failure detection circuit 331 according to the DGU command applied from the maintenance control execution section If, and transfers it to the service processor 1.
