Abstract
A method, computer system, and a computer program product are provided for operating a primary and a backup RAID storage array. A disk drive configuration is loaded into a disk controller in a primary RAID array and a disk controller in a backup RAID array. The disk drive configuration includes a schedule for a sequence of selectively power cycling the disk drives, which is executed by the disk controller in the primary and in the backup RAID arrays. Upon detecting a disk failure, each disk controller executes a recovery procedure according to instructions included in the disk drive configuration. Recovery procedure includes suspending power cycling all disk drives and powering on all intentionally powered off disk drives. Data is copied from the corresponding backup RAID array disk drive to primary RAID array to rebuild the failed drive. The RAID configuration remains in this state until failed disk drive is repaired.
