PROBLEM TO BE SOLVED: To provide an apparatus and a method to reconfigure a storage array disposed in a data storage system. SOLUTION: Each of a plurality of data storage devices is assigned to one of a plurality of data storage arrays, or is assigned as a spare device. The method detects an unassigned data storage device, and determines if any of the plurality of data storage arrays comprises a degraded data storage array. If the method determines that any of the plurality of data storage arrays comprises a degraded data storage array, then the method determines if the unassigned data storage device can be used to restore the degraded data storage array to optimal reliability, optimal performance, and optimal efficiency. If the method determines that the unassigned data storage device can be used to restore the degraded array to an array comprising optimal reliability, optimal performance, and optimal efficiency, then the method reconfigures the degraded data storage array to comprise the unassigned data storage device.
