Document Type and Number:
WIPO Patent Application WO/2017/208319
Kind Code:
A1
Abstract:
A storage system having a plurality of storage devices comprises a control module for providing a user with a virtual storage device containing a virtual volume to which a volume is mapped. If a command for setting a local copy from a first virtual volume to a second virtual volume included in the virtual storage device is received, the control module specifies a plurality of first volumes mapped to the first virtual volume and a plurality of second volumes mapped to the second virtual volume, and changes the configuration of the copy pair such that there is a single data writing path to the copying destination volume of the local copy, thereby setting the local copy from the first volume to the second volume contained in the same storage device.
