Zusammenfassung:A storage control device and a storage control method are provided. If a first failure detector of a first controller does not detect a failure in a second controller, a first input/output processor of the first controller copies the contents of a first volatile memory of the first controller to a second volatile memory of the second controller. On the other hand, if the first failure detector detects a failure in the second controller, the first input/output processor copies the contents of the first volatile memory to a first non-volatile memory of the first controller.
