A storage control device includes a first memory, a second memory, and a processor. The first memory stores therein a first startup program for starting up the storage control device. The second memory stores therein a second startup program for starting up the storage control device. The processor performs a startup process of starting up the storage control device by executing the first startup program stored in the first memory. The processor performs diagnosis for the first memory during the startup process. The processor restores, in a case where an abnormality is detected in a first portion of a first area of the first memory, first data stored in the first portion by overwriting the first data with data of a part of the second startup program stored in the second memory. The first area is a storage area in which the first startup program is stored.
