Abstract
A first storage system comprises an information processing device and a first volume, and is connected to an information processing device. A second storage system comprises a second volume and is connected to the first storage system. The second storage system performs power supply control relating to the second volume in cooperation with a remote copy, such that the remote copy and the power supply control are performed efficiently. Thus, a remote copy function performs power supply control of an HDD comprising a secondary volume of a remote copy pair, to match data copy status (such as stopping data copy to the secondary volume, or differential copying). Thus, longevity of the HOD and lower use of active power of a storage system can be realized.
