ABSTRACT:
A process control system for activating a storage device e.g., disk array device including a plurality of disk drive and control units for operating the disk drives in parallel, executes a background processing while a process for activating the disk array device is being executed. Preferably, when the disk array device is powered on, the apparatus carries out a diagnosis in the respective control units, and applies a locating process to the respective disk drives so as to detect a defective disk drive. If defect is detected, data stored in the defective disk drive is reconstructed in a spare disk drive.
