Abstract
A RAID system employs a storage controller, a primary storage array having a plurality of primary storage units, and a spare storage pool having one or more spare storage units. A method of operating the storage controller in managing the primary storage array and the spare storage pool involves a testing by the storage controller of at least one repair service threshold representative of one or more operational conditions indicative of a necessity to repair at least one of the primary storage array and the spare storage unit, and a selective initiation by the storage controller of a repair service action for repairing one of the primary storage array and the spare storage unit based on the testing of the at least one repair service threshold.
