Next, the operation of the present invention will be described in detail with reference to the drawings.

The threshold value setting means 11 is activated by an operator's instruction (111), a threshold value set by the operator is obtained (112), and stored in the threshold value information area 53 in the failure information file 5 (113).

Next, the processing when a failure occurs in the peripheral device will be described. Peripheral device failure monitoring means 21
Monitors the input / output to / from the failed magnetic disk device 3, and when a failure occurs in the input / output operation (211), stores the failure information of the failed failed magnetic disk device 3 in the failure information storage area 22 ( 212), and notifies the operating system 10 that a failure has occurred (213). When the operating system 10 receives a notification indicating that a failure has occurred from the peripheral device failure monitoring means 21 (121), it activates the failure information storage means 12 (122), and the activated failure information storage means 12 is activated. Reads the fault information stored in the fault information storage area 22 from the peripheral control device 2 (1
23), failure information is stored in the failure information section 512 indicated by the pointer section 511 in the failure information storage area 51 (124). After storing the failure information, the pointer portion 511 in the failure information storage area 51 is updated to indicate the stored failure information (125), and the failure information storage area 51 is updated.
It is checked whether or not the failure information section 512 therein is full (126). When the failure information section 512 in the failure information storage area 51 is full, the oldest failure information stored in the failure information section 512 in the failure information storage area 51 is deleted (127). Then, the failure information totalizing means 13 is activated (128), and the process is terminated. The failure information totaling means 13 activated by the failure information accumulating means 12 clears the contents of the failure information totaling area 52 in the failure information file 5 (13
1), the failure information section 5 in the failure information storage area 51
12 is read (132), and it is checked whether the information is the failure information of the failed magnetic disk device 3 in which the failure has occurred (133). If the read fault information is the fault information of the fault magnetic disk device 3, the total processing is performed from the information in the fault information total area 52 (134). afterwards,
It is checked whether all the fault information accumulated by the pointer section 511 in the fault information accumulating area 51 has been processed (135). When the totaling process is not completed, the totaling process is performed again from the process (132) of reading the next failure information. If the totalization process has been completed, the peripheral device error rate calculation means 14 is activated (136) and the process ends.
The peripheral device error rate calculation means 14 activated by the failure information collection means 13 obtains a collection result from the failure information collection area 52 in the failure information file 5 (14
1), the error rate is calculated (142), and the threshold value is obtained from the threshold value information area 53 in the failure information file 5 (14).
3) It is checked whether the error rate exceeds a threshold value (144). If the error rate does not exceed the threshold value, the process ends. If the error rate exceeds the threshold value, the data transfer means 15 is activated (145) and the processing is terminated. The data transfer means 15 activated by the peripheral device error rate calculation means 14 transfers the data stored in the failed magnetic disk device 3 whose error rate exceeds the threshold value to the normal magnetic disk device 4 (151). ), And activates the faulty peripheral device disconnecting means 16 (152) to end the process. The faulty peripheral device disconnecting means 16 activated by the data transfer means 15 disconnects the faulty magnetic disk device 3 whose error rate exceeds a threshold value from the system (161) and disconnects the faulty magnetic disk device 3 from the system. Is output to the remote maintenance console 6 (162), and the process ends.

As described above, in this embodiment, the peripheral device maintenance work can be performed promptly by outputting to the remote maintenance console a message indicating that the peripheral device whose error rate exceeds the threshold is disconnected from the system. It is possible.

In this embodiment, an example is shown in which the central processing unit comprises threshold setting means, failure information accumulating means, failure information totaling means, peripheral device error rate calculating means, data transfer means, and failure peripheral device disconnecting means. However, it is also possible to configure this into another processing device.

Further, the example in which the message indicating that the faulty peripheral device has been disconnected from the system is output to the remote maintenance console has been shown, but it may be configured to output it to another information display device.

[0014]

As described above, according to the present invention, each time a failure occurs, the failure information is collected and accumulated from the peripheral control device, and then the totalization process is performed to calculate the error rate for each peripheral device and specify the specified threshold value. The data stored in the peripheral device that exceeds the threshold is transferred to the normal peripheral device, the peripheral device whose error rate exceeds the threshold is disconnected from the system, and the message indicating that the failed peripheral device is disconnected from the system is displayed. Outputting to the device has the following effects.

I) By disconnecting the peripheral device whose error rate exceeds the threshold value from the system, the peripheral device which is likely to cause a failure is not used.

II) By storing the data stored in the peripheral device in which the error rate exceeds the threshold value in the normal peripheral device, the data stored in the peripheral device in which the failure has occurred is guaranteed.
