摘要
In a RAID management apparatus, a disk determination unit accesses each of RAID devices, determines a copy source disk, and sets a pointer of the determined copy source disk into a disk management table stored in a storage unit. When an input-output (I/O) processing unit accesses a disk, if an I/O error occurs on the disk, as a result a copy source disk and a copy destination disk are switched; the I/O processing unit renews a pointer associated with the copy source disk in the disk management table stored in the storage unit, and a disk notification unit notifies that the copy source disk and the copy destination disk are switched.
