A computer system (10) includes a central processing unit (11), a computer maintenance unit (12) and an input/output processing section (13) having a plurality of input/output processing units (13b) each of which is associated with a respective input/output device (14). When a failure occurs in an input/output processing unit, the input/output processing unit control section (13a) detects the occurrence of a failure, reports it to the central processing unit (11) and requests the computer maintenance unit (12) to acquire failure information from a failed input/output processing unit (13b) and to initialize the input/output processing unit. After acquisition of the failure information, the computer maintenance unit (12) initializes the failed input/output processing unit (13b) and reports the termination of the initialization to the input/output processing unit control section (13a). Afterward, the input/output processing unit control section (13a) informs the central processing unit (11) of the termination of the initialization of the failed input/output processing unit. |
