ABSTRACT:
A computer system includes a host computer, a disk control device controlling operation of a storage sub-system, and a management server managing configuration of the storage sub-system. The host computer registers the result of grouping of a plurality or volumes in the storage sub-system according to a use purpose in a volume management table including a volume identifier, a physical address, and a group identifier allocated in the disk control unit. During access to the volume via the host, the disk control unit obtains the physical address belonging to a storage belonging to a group identical to the group input via the host, notifies information described on the volume list of the storage allocated at the physical address to the management server, and causes the server to display the information.
