Abstract
A RAID control apparatus is able to cooperate with another RAID control apparatus to control at least one RAID apparatus. The RAID control apparatus comprises a diagnosis unit and a control unit. The diagnosis unit diagnoses the other RAID control apparatus when an disk error is detected. The control unit stops controlling the RAID apparatus in cooperation with the other RAID control apparatus, whereby only the RAID control apparatus controls the RAID apparatus, when the diagnosis unit determines that the other RAID control apparatus has a trouble. The control unit causes only the other RAID control apparatus to control the RAID apparatus when a disk error is detected while only the RAID control apparatus is controlling the RAID apparatus.
