摘要： Access to a plurality of logical devices is enabled regardless of the number of ports provided in a storage system and the number of logical devices that can be allocated to a single port, thereby improving the usability of the logical devices. A storage system comprises a plurality of logical devices, a target device which is the object of access from a computer, and a juke box system for allocating one of the plurality of logical devices to the target device. The juke box system changes the logical device that is allocated to the target device in accordance with a request from the computer.

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.

摘要： With the migration of a logical volume between virtualization apparatuses, there has been a need to change the setting of a host computer in order to access a migration destination logical volume. In a control method for a computer system including a host computer, one or more storage systems, and plural virtualization apparatuses, a first virtualization apparatus includes a first memory and manages a first logical volume to which the host computer issues an access request, and a second virtualization apparatus includes a second memory and manages a second logical volume to which the host computer issues an access request, wherein the control method associates a first real storage area on the storage system, which has been associated with the first logical volume, with the second logical volume, and stores, in the second memory, first identification information that uniquely identifies the first logical volume within the computer system.

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： 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.
