14-n is detected and output to the failure information receiving unit 6 via the signal line 23. The failure information receiving unit 6, which has received the failure information from the failure information detecting unit 7, notifies the failure information collecting unit 3 via the signal line 22 that the processing devices 14-1 to 14-n have failed. I do. The failure information collection unit 3
The processing device 14-1 receives information from the failure information receiving unit 6 according to the information.
14-n are in a fault state, and signal line 2
By referring to the address table 4 of the internal storage device 5 through 0 and 21, a register from which data is to be collected is recognized,
After reading out the contents of the register via the signal lines 26 and 27 and storing it in the failure information storage area 2 as logout data, a logout request is made to the logout control unit 9 of the service processor 8. Logout control unit 9
Stores the logout data read from the failure information storage area 2 via the signal lines 24 and 25 in the magnetic disk device 11 via the signal lines 30 and 31.

FIG. 3 is a flowchart showing the operation of the embodiment of FIG. 1 when the failure information collecting unit 3 collects the contents of the registers of the processing units 14-1 to 14-n while referring to the address table 4. is there.

The failure information collecting unit 3 includes processing units 14-1 to 14-1.
When the contents of the register 14-n are collected, first, the value A of the number of blocks 45 in the address table 4 is referred to recognize the presence or absence of an address sequence (step 61), and if there is no address sequence, the process ends. . If you have an address column,
Address column attribute 46 of block 41 or block 42
, It is recognized whether the address sequence is a continuous read type address sequence or a single read type address sequence (step 6).
2).

If the address string is a single read type address string, the process proceeds to step 63, where the value C of the register number 47 is recognized, the address values D to I are read from the addresses 48 to 50, and the register number is 0. Until, the contents of the registers of the processing devices 14-1 to 14-n are collected and stored in the failure information storage area 2 (steps 63 to 67).

If the address string is a continuous read type address string, the process proceeds to step 68, where the number of entries is 5
The number of consecutive addresses is recognized by the value K of 2.
Next, the value L of the start address 53 and the value M of the last address 55 of the first entry 43 are read (steps 69 and 70), whereby the processing units 14-1 to 14-n are read.
The contents of the registers of the processing units 14-1 to 14-n are sequentially updated until the value of the address becomes larger than the value M of the final address. Are collected (steps 71 to 73).

When the contents of the register have been collected by the first entry 43, the values P of the start address 57 and the value Q of the end address 58 of the second entry 44 are used by the processing units 14-1 to 14-n. Collect the contents of the register. This operation is repeated by the value K of the number of entries 52 (steps 74 to 75).

As described above, the failure information collection unit 3 sets each address string as one block, collects the contents of the registers of the processing units 14-1 to 14-n according to the address string attribute of each block, and stores the contents in the failure information storage area. The operation of storing the data in 2 is repeated by the value A of the number of blocks 45.
