<P>PROBLEM TO BE SOLVED: To perform restoration without replacement of a hard disk in the event of false detection of a hard disk failure even if there is no failure in the hard disk. Ž<P>SOLUTION: A failure detection unit 11 detects a failure which is caused in hard disk drives 20-1 to 20-N. A restart unit 14 restarts the RAID controller device 10 when the failure detection unit 11 detects a plurality of failures of the hard disk drives 20-1 to 20-N within a predetermined time, and a reconfiguration unit 16 reconfigures, when restarting the RAID controller device 10, a logic drive based on logic drive configuration information stored by the hard disk drives 20-1 to 20-N.
