METHODS FOR REDUNDANT ARRAY OF INDEPENDENT DISK (RAID) STORAGE RECOVERY

摘要

A method for managing storage devices in a storage subsystem having an array of storage devices includes receiving an error message; determining that the error message indicates that at least one storage device in the array of storage devices has failed; collecting an array record comprising storage device characteristics of the failed storage device in response to determining that the error message indicates that at least one storage device has failed; collating a candidate record comprising a plurality of candidate entries; comparing storage device characteristics of the failed storage device of the array record with the storage device characteristics of each of the candidate entries; identifying a first candidate storage device having storage device characteristics that match the storage device characteristics of the failed storage device; and identifying a second candidate storage device having storage device characteristics most similar to the storage device characteristics of the failed storage device.
