Abstract
A computer-implemented method for managing storage devices in a storage subsystem having an array of storage devices, according to one embodiment, includes determining that at least one storage device in the array of storage devices has failed. Storage device characteristics of the failed storage device are compared with storage device characteristics of each of a plurality of candidate devices, and an attempt is made to identify a first candidate storage device having storage device characteristics that match the storage device characteristics of the failed storage device. A second candidate storage device having storage device characteristics most similar to the storage device characteristics of the failed storage device is identified in response to not identifying a candidate device that matches the failed storage device.
