摘要： A new storage unit is installed such that installation costs are suppressed and functions of the new storage unit can be utilized sufficiently. An access right is changed such that the new storage unit (second storage unit) can access an existing first storage unit (S502). A logical device relating to a storage device of the first storage unit is assigned to a logical device of the second storage unit (S503). Path definition and device recognition in a host computer are performed such that the host computer can access the assigned logical device of the second storage unit (S504, 505). Input-output setting of the host computer is changed such that processing of an input-output from the host computer to the device of the first storage unit is requested to the second storage unit (S506).

摘要： A remote copy technique according to which data of a primary volume is migrated while continuing remote copy processing and receiving access requests from a host. A remote copy system comprises a first storage system having a first primary volume, a second storage system having a second primary volume and a third storage system having a secondary volume, and remote copying is performed between the first primary volume and the second volume. When data in the first primary volume is migrated to the second primary volume, an access request from the host to the primary volume is transferred to the second primary volume. Further, the second storage system stores write data received from the host and data of the first primary volume received from the storage system, into the second primary volume. Out of data stored in the second primary volume, the second storage system sends data determined by management information received from the first storage system, to the third storage system.

摘要： In a storage subsystem, performance tuning is performed with respect to whole logical devices including external storage subsystems that are not directly connected to host computers.Physical storage units presented by the external storage subsystems are defined as logical devices of the storage subsystem itself, and I/O processing requests from the host computers are relayed to those logical devices. At the time of relaying, I/O processing conditions are monitored. When there exists an external storage subsystem whose load is high, then, operating conditions of ports and processors are examined. In the case where the load can be reduced by changing the configuration of those ports and processors, the configuration is changed to reduce the load. In the case where the load can not be reduced, data is migrated from a logical device having a high load to a logical device having a sufficient performance.

摘要： In a storage system having a plurality of control units each connected with a plurality of disk units, it is provided that a replication is created in the volume of the disk units connected to different control units. The replication creation unit of a given control unit creates a replication in the volume of the disk unit connected to other control units in such a manner that the original volume information, the replication volume information in the control unit and information on the other control units are registered as volume pair information. Based on this volume pair information, a replication creation request is transmitted to the other control units.

摘要： System availability is improved in a second storage system, connected to a first storage system, and having means for virtualizing devices within the first storage system as its own devices. When the virtual storage system or a storage management server detects a fault in the virtual storage system, the management server investigates the range affected by the fault, identifies a device for which measures must be taken, determines a transfer target device which accommodates the performance, reliability, and other attributes of the affected device, and issues a device transfer instruction for the virtual storage system. In the virtual storage system, the data of the device specified by the instruction within the virtual storage system is transferred to a device, specified by the management server, within the system itself, or to a device within another virtual storage system.
