A storage area management method utilizes a storage system power saving function by using copy pair operation information obtained by acquiring an operation schedule of an application host. The method includes retrieving at least one candidate logical volume for creating a primary logical volume from a plurality of storage device groups, judging whether the retrieved candidate logical volume(s) on a primary side satisfies a condition of the primary logical volume, retrieving at least one candidate logical volume for creating a secondary logical volume from the storage device groups, judging whether the retrieved candidate logical volume(s) on a secondary side satisfies a condition of the secondary logical volume, and creating a copy pair based on the retrieving and judging. The method enables appropriate arrangement of the primary and secondary logical volumes, and creation of a copy pair for an appropriate disk device group, thereby managing and saving storage system power.
