摘要:
A storage control apparatus monitors whether or not one or more storage management apparatuses are properly operating. A recovery target extraction unit extracts a recovery target storage area when the existence of a malfunctioning storage management apparatus is detected, the recovery target storage area being a storage area that has been duplexed with a storage area of the malfunctioning storage management apparatus. A duplexing control unit performs control so that, if the recovery target storage area 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. If the recovery target storage area 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.
