1. A storage control device comprising:

  • a first memory that is a volatile storage configured to store backup target data, the backup target data including first information on control of a storage device;

    a second memory that is a non-volatile storage; and

    a processor coupled to the first and second memories, the processor configured to execute;

    power failure processing in which the processor detects a power failure and writes the backup target data in the second memory,abnormality processing in which the processor detects an abnormality other than the power failure, acquires second information on a state of hardware at time of detection of the abnormality, and writes the first information and the second information in the second memory, andpower failure suspension backup processing in which the processor detects the abnormality during execution of the power failure processing, suspends the power failure processing, acquires the second information, and writes backup data, the backup data being the backup target data that has not been written to the second memory during the power failure processing, and the second information in the second memory.
