摘要:
A storage control apparatus manages a plurality of storage devices which belong to an RLU such that data is made redundant between different storage devices. If a first storage device fails, a rebuild controller executes a rebuild process to store the same data as recorded in the first storage device in a spare storage device. When the rebuild controller executing the rebuild process has failed in reading out data from a second storage device, a data recovery controller restarts the first storage device, and reads out data to be stored in the spare storage device from the restarted first storage device.
