Abstract
Modern disk array apparatus are capable of providing a plurality of logical disks within one cabinet. The present invention provides a disk array apparatus in which logical disks can be easily re-arranged within the array, or added to the array. An array controller logically controls at least one disk apparatus as one logical disk. The array controller also changes positional information within the drive modules stored within the disk apparatus. Information is matched indicating the position of the relevant disk apparatus within the logical disk. Therefore, after transposition of a particular logical disk, a new logical disk can be accurately recognized.
