摘要： When a computer 10 receives a request from the client computer 30 to access snapshot files, the target device to be used is identified. The computer 10 makes a request to the identified target device TD for attachment of the logical device LDEV that stores the snapshot files for which access is requested. When the computer 10 receives notification that the attachment has ended from the storage device system 20, the identified target device is mounted on the directory in which the snapshot files are stored.

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： 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： In a storage system comprising multiple storage devices with different interfaces, the characteristics, including the type of interface, of the storage devices on which the source volume is constructed are checked, a volume having the characteristics that match them is selected as the destination volume, and the contents of the source volume are automatically replicated into the destination volume. Candidates for replication (destination) volumes are automatically selected and presented to the user or the administrator, and replication volumes are automatically allocated, without requiring the user or the system administrator to be concerned with the characteristics of the storage devices.

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： 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.
