Abstract:
The management server performs a release/non-release selection determining whether or not to release all of the real storage areas assigned to a virtual volume switched from a used target to an unused target. The management server exercises control to determine whether or not to release all of the real storage areas assigned to the specified virtual volume in accordance with the result of the release/non-release selection.
