摘要： In a storage subsystem, performance tuning is performed with respect to all of the logical devices including external storage subsystems that are not directly connected to host computers. The physical storage units presented by the external storage subsystems are defined as logical devices of the storage subsystem, and I/O processing requests from the host computers are relayed to the logical devices. At the time of relaying, I/O processing conditions are monitored. When the load of an external storage subsystem is high, then operating conditions of ports and processors are examined. When the load can be reduced by changing the configuration of those ports and processors, the configuration is changed to reduce the load. When 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： 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). Seleted figure: FIG. 5.

摘要： The present invention transfers replication logical volumes between and among storage control units in a storage system comprising a plurality of storage control units. To transfer replication logical volumes from a storage control unit to a storage control unit, a virtualization device sets a path to the storage control unit. The storage control unit then prepares a differential bitmap in order to receive access requests. When the preparation is completed, the virtualization device makes access requests to the storage control unit. The storage control unit then hands over the access requests to the storage control unit. Subsequently, the storage control unit performs a process so that the access requests are reflected in a disk device and performs an emergency destage of storing data in a cache memory into disk device. When the emergency destage is ended, the storage control unit connects to an external storage control unit and hands over access requests to the external storage control unit.

摘要： The storage system includes a storage subsystem including a plurality of storage units and a storage control device coupled to a computer and the storage subsystem, the storage control device providing the host computer with a logical unit assigned to a storage unit of the storage subsystem. The storage control device receives a first access request from the computer to the logical unit and sends a second access request to the storage unit of the storage subsystem according to a relation between the storage unit of the storage subsystem and the logical unit assigned to the storage unit. Performance information relating to the second access request by the storage control device is obtained so that the storage control device determines performance relating to the logical unit assigned to the storage unit of the storage subsystem.
