Abstract
According to one embodiment, a disk array control device manages a plurality of drives as a single logical drive. The disk array control device includes a first register configured to store a to-be-accessed drive number which is designated by a host, and a control module. The control module is configured to receive a command from the host, determine whether the received command is a predetermined command which is used for maintenance of each of the drives, and execute, in a case where the received command is the predetermined command, a pass-through process of sending the received command to the drive which is designated by the to-be-accessed drive number in the first register.
