ABSTRACT:
The storage control device of the present invention detects faults on the disk drives at an early stage, thus enhancing convenience of use. The disk drives are switchingly connected to a subordinate communication control unit via a switching circuit. An error information collection unit of an error monitoring unit detects errors which have occurred at each port of the switching circuit. The errors which have been detected are stored in an intermediate storage unit, and are input via an error information notification unit to a fault recovery control unit of the subordinate communication control unit. By doing this, it is possible to immediately specify whether or not a fault has occurred on any of the disk drives, and to start a fault recovery procedure.
