ABSTRACT:
To provide a technique by which, if the number of active disk groups in a storage device is restricted, an appropriate logical volume in the storage device can be used. A management apparatus manages a storage device provided externally. The management apparatus obtains management data indicating which of a plurality of disk groups included in the storage device is active, from the storage device. In addition, the management apparatus executes predetermined processing with reference to the management data in order to utilize a logical volume belonging to a disk group in the storage device while ensuring that the number of active disk groups in the storage device does not exceed an upper limit value.
