Abstract
A storage system includes a plurality of control devices to control output and input of data to and from a storage device. At least one of the plurality of control devices includes an interface unit and an arithmetic processing unit. The interface unit receives an instruction regarding output or input of data to or from the storage device. The arithmetic processing unit receives the instruction from the interface unit and executes the instruction. The arithmetic processing unit selects, when an error has occurred in a specific interface unit, a first processing unit and requests the first processing unit to execute saving processing for saving dump data of the specific interface unit. The arithmetic processing unit selects, when a usage rate of the first processing unit goes beyond a threshold during execution of the saving processing, a second processing unit and requests the second processing unit to execute the saving processing.
