<p>A process control system for activating storage device e.g., disk array device (3) including a plurality of disk drive and control units (4, 7, 8 and 9) for operating the disk drives in parallel, is operative to execute a background processing while a process for activating the disk array device (3) is being executed. Preferably, when the disk array device is powered on, the apparatus is operative to carry out a diagnosis in the respective control units (4, 7, 8 and 9) per se, and to apply 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. <IMAGE></p> |
