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