Abstract:
A storage control apparatus is configured to access a physical storage region of a storage apparatus corresponding to a logical address of a logical storage region, when an error is detected, specify a physical address of the physical storage region, for each of a plurality of regions generated by dividing the physical storage region using a plurality of division conditions different from each other, specify a number of times in which the error is detected, specify a recovery target region in which the number of times is equal to or greater than a first value, specify a first division condition generating the recovery target region, select, from a plurality of recovery methods, a first recovery method corresponding to the first division condition, and cause the storage apparatus to recover a first logical address in the logical storage region corresponding to the recovery target region by using the first recovery method.
