Abstract
A storage system is disclosed comprising a management computer and multiple storage subsystems with multiple volumes accessible to a host computer. The host computer sends volume configuration information to the management computer. Each storage subsystem retrieves information from the volume directory corresponding to a requested volume and sends it to the management computer. The management computer comprises a volume information table holding the volume configuration information obtained from the host computer, information on storage subsystems, and use-related ID group IDs; a unit which identifies the volumes belonging to a specified group ID, locates the storage subsystems these volumes belong to, and obtains information on the desired volumes from their corresponding volume directories; and a display device which displays information on the usage of the volumes that is obtained from storage subsystems. Thus, volume information in multiple storage subsystems can be collected in an integrated manner, thereby reducing management overhead.
