    摘要: 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.

    摘要: 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.

    摘要: A computer system having a plurality of host computers and a storage system is provided which allows any one host computer to perform a global copy operation on any arbitrary or all storage areas in the storage system. To this end, storage areas provided by the disk devices are grouped into groups by allocating group numbers to a plurality of specified storage areas. The copy operation can be performed by specifying desired groups. Each of the groups is made up of sub-groups and the sub-groups are defined for each computer to assure a consistency of copy order of the sub-groups.

    摘要: A computer system and method which stores path definition information including a storage ID, a volume ID, and validities of paths between a host computer and a first or second storage system identified by the storage ID for accessing a volume identified by the volume ID in one of the storage systems, sends an I/O request via the paths, based on the path definition information, receives information indicating the storage and volume IDs, and updates the path definition information. During initial copying from the second to the first volume, validity corresponding to a first path is set to “Invalid” and validity corresponding to a second path is set to “Valid”. After completion of initial copying, the validity corresponding to the first path included in the path definition information is changed to “Valid.”

    摘要: Related plural logical volumes can be used after switching over from the host computer therein. A switching command, which a host computer sends, makes a storage device search for a switching target volume, from the volume tables, that is identical to identification information of the switching target volume received among switching target candidate volumes that form a volume pair relation with the switching source volume. The storage device memorizes an intra-host ID of the switching target volume and an intra-storage ID of the switching target volume in a switching table with a correspondence there between. The storage device acquires the intra-storage ID of the switching target volume in reference to the switching table in the case of receiving an access request, such that the intra-host ID of the switching source volume is used as a key, and executes switching to access to the switching target volume.
