Patent ID: 7913109

Claim:
A storage control apparatus that performs control so that storage areas of different storage management apparatuses are duplexed, comprising: monitoring unit monitoring whether or not the storage management apparatuses are properly operating; recovery target extraction unit extracting a recovery target storage area when the existence of a malfunctioning storage management apparatus is detected by the monitoring unit, the recovery target storage area being a storage area that has been duplexed with a storage area of the malfunctioning storage management apparatus; and duplexing control unit performing control so that, if the recovery target storage area extracted by the recovery target extraction unit has no data stored therein, the recovery target storage area is duplexed with a storage area that has no data stored therein and that is unused, and if the recovery target storage area extracted by the recovery target extraction unit has data stored therein, the recovery target storage area is duplexed with a non-duplexed storage area and the data stored in the recovery target storage area is copied into the non-duplexed storage area.
