A disk array is an enterprise storage system which contains multiple disk drives. It is differentiated from a disk enclosure in that an array has cache and intelligence so that it can perform functions like RAID and virtualization.

On the other hand, in conventional diskarrays using the FC drives and SCSI drives, to increase their reliability, symptom of failure of the drives is monitored, and when many bad sectors occur, preventive copy is executed.
On the other hand, when no response is received from the ATA disks 401 to 403 until the retrying time is reached, it is judged that the retry is under execution in the ATA disks 401 to 403, and a "retrying" response is transmitted to the diskarray controller 200 (1013).
After that, when the process completion response is received from the ATA disks 401 to 403 by the time that the retrying time has elapsed, it is judged that the retry has been executed in the ATA disks, and a "recovered" response is transmitted to the diskarray controller 200.
