Abstract: Performance degradation caused by a failure occurring in a disk array device is suppressed. The disk array device comprises the dual structure controllers which are respectively connected to the host computer through the connection path, and a plurality of physical disks, wherein the controller comprises the failure sensing unit which senses a failure of the device, and the host interface control unit which, in a case where a failure is sensed by the failure sensing unit, when an inquire about a connection path to be preferentially used is made from the host computer, notifies the connection path connected to the other controller as a preferential path.
