ABSTRACT:
The present invention relates to an arrayed recording apparatus having spare devices for replacing faulty disk drives. Each of the SCSI controllers in the arrayed recording apparatus connects to a driver/receiver and further connects to spare disk drives. Each of the SCSI controllers accesses the spare disk drive by setting a receive/enable signal effective to the driver/receiver. Unused ID numbers are assigned to the spare disks. If a disk drive develops a fault, the RAID controller RC requests the SCSI controller to replace the faulty disk drive with the spare disk drive.
It is possible to attain the function of the hot stand-by system without comprising a specific spare controller.
