ABSTRACT:
If a failure occurs in any of a plurality of data disks, and if a controller receives a read request from a host computer for the RAID group including the failed data disk, the controller performs data recovery using data stored in the other data disks in the RAID group, and transmits the recovered data to the host computer and also writes the recovered data to a spare disk.
