ABSTRACT:
A disk array storage system and error recovery method wherein recovery from disk errors is achieved using automated selective power cycling. Initially, identification is made of a faulty disk drive in the array that exhibits an error condition in which the drive fails to perform a requested operation. The faulty disk drive is selectively power cycled while power to other disk drives in the array is maintained. Following the power cycling sequence, the requested operation is retried.
