A disk array control apparatus controls a disk array having a redundant configuration with two or more disk devices and a spare disk provided for lack of redundancy in the disk array. And the disk array control apparatus includes a failure detecting unit for detecting the lack of redundancy in the disk array, and a rebuilding control unit for performing rebuilding processing on a dedicated spare disk device assigned to the disk array with the lack of redundancy, the dedicated spare disk being the spare disk dedicatedly assigned to the two or more disk arrays including the disk devices having a same characteristic as that of the spare disk. |
