Abstract
In one embodiment, a system includes a storage subsystem having an array of storage devices; a receiving component for receiving an error message; a determining component for determining that the error message indicates that a storage device has failed; a collecting component for collecting an array record having storage device characteristics of the failed storage device; a collating component for collating a candidate record having a plurality of candidate entries; a comparing component for comparing storage device characteristics of the failed storage device of the array record with the storage device characteristics of each of the candidate entries; and an identifying component for identifying a first candidate storage device having storage device characteristics that match the storage device characteristics of the failed storage device or a second candidate storage device having storage device characteristics most similar to the storage device characteristics of the failed storage device.
