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 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 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： In a copy control method, during a process for the acquisition of a data copy at a designated time, a recovery period of time can still be reduced when an input/output request is issued for copy source data at the designated time. For a system that includes a first storage device in which data are stored, a second storage device that obtains a data copy, and a host computer that writes data to the first storage device, the second storage device obtains blank input/output requests that are issued at predetermined time intervals if the host computer does not generate an input/output request for the first storage device, and the second storage device determines that a time closest to a predetermined data copy acquisition time, which is a target time for the acquisition of a data copy, is a copy execution time for the acquisition of a data copy.

摘要： In a system for storing data as a backup purpose to a separate storage apparatus, data of a copy source is matched with data of a copy destination in a predetermined time. A host computer attaches an identifier to a write request and then transmits the resulting write request to another storage apparatus for every segment of business. The host computer calculates an amount of data which can be copied (backup) within a given time for every identifier, and then, issues a backup instruction to the storage apparatus.

摘要： A first storage system sets a storage area of a first disk drive as a first volume, and misrepresents an identifier of the storage system and an identifier of the first volume. A second storage system sets a storage area of a second disk drive as a second volume, and misrepresents an identifier of the storage system and an identifier of the second volume. The first storage system copies data of the first volume in the second volume. The second storage system copies data of the second volume in the first volume. A management computer determines whether there is a match between the data of the first volume and the data of the second volume. When it is determined that there is not match, the host computer accesses only one of the first volume and the second volume that stores the latest data.
