Disk array system, disk array method, and computer product

摘要

A disk enclosure issues various small computer system interface (SCSI) commands to hard disk drives (HDDs), and acquires and stores therein disk detail data on all the HDDs. A disk controller is connected to the disk enclosure via an exclusive SCSI cable and the disk controller issues the SCSI command for requesting the disk detail data in batch. Upon receiving the SCSI command, the disk enclosure returns the disk detail data on all the HDDs in batch, in response to the SCSI command.
