Abstract
The present invention is to provide a method for displaying a copy pair in which a distinction can be made between change of pair state performed intentionally by a user and change of pair state performed not intentionally by the user. When a backup instruction for PVOL is transmitted from the task server to the storage subsystem, the subsystem records, on a table, backup execution condition information including an ID of a copy pair having the PVOL. The monitoring program acquires the pair state of each copy pair and the backup execution condition information from the subsystem, and displays the pair state of the copy pair having the ID contained in the backup execution condition information, and the pair state of other copy pair, in different display modes.
