    摘要: A disk array device includes a controller that sets a session pertaining to a copy source disk and a copy destination disk, and without copying the entire data that is recorded in the copy source disk to the copy destination disk, copies to the copy destination disk only the data that is recorded in a data space for writing. Further, if data for reading does not exist in the copy destination disk, the controller searches data from the copy source disk and transfers the searched data to a host computer.
