Zusammenfassung:A method for servicing a redundant array of independent storage drives (i.e., RAID) includes performing a service call on the RAID by performing the following steps: (1) determining whether the RAID includes one or more consumed spare storage drives; (2) in the event the RAID includes one or more consumed spare storage drives, physically replacing the one or more consumed spare storage drive with one or more non-consumed spare storage drives; and (3) initiating a copy process that copies data from a storage drive that is predicted to fail to a non-consumed spare storage drive associated with the RAID. The service call may then be terminated. After the service call is terminated, the method waits for an indication that a number of non-consumed spare storage drives in the RAID has fallen below a selected threshold. A corresponding apparatus and computer program product are also disclosed.
