Storage control device, and error information management method for storage control device

摘要

The storage control device (1) of the present invention detects faults on the disk drives (5) at an early stage, thus enhancing convenience of use. The disk drives are switchingly connected to a subordinate communication control unit (2C) via a switching circuit (4) . An error information collection unit (7A) of an error monitoring unit (7) detects errors which have occurred at each port (4A, 4B) of the switching circuit. The errors which have been detected are stored in an intermediate storage unit (7B), and are input via an error information notification unit (7C) to a fault recovery control unit (2C1) 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.
