of primary storage units and a spare storage pool having at least one spare storage unit, the method comprising:
operating the storage controller to detect any failure in a primary storage unit within the primary storage array;
operating the storage controller to migrate data from the primary storage array to the spare storage pool in response to a
detection of a failure in the primary storage unit within the primary storage array;
operating the storage controller to test at least one repair service threshold in response to the detection of the failure
in a storage unit within the primary storage array, the repair service threshold representative of at least one operational
condition indicative of a necessity to repair at least one of the primary storage array and the spare storage unit; and
operating the storage controller to selectively initiate 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.
