摘要： A first storage control device is provided with a virtual LU for showing a logical volume possessed by a second storage control device as if it were its own volume. When data processing requested from a host device is, for example, a specific processing of large load (such as direct backup, logical volume copy, and so on), whether or not the requested processing can be executed by the second storage control device is judged. When it is executable, a command is transmitted to the second storage control device to make it take over the processing.

摘要： A disk array apparatus capable of effecting saving and operation of data through a simple construction. When a host computer sets “write inhibit” or “read/write inhibit” for an LDEV which is set on a first storage device, this setting is registered in an access attribute management table and is also reflected onto a migration management table. A migration control program moves the LDEV for which access limitation has been set to a lower-speed (lower-performance) second storage device or to an external storage device. When the access limitation is released, the moved LDEV is restored to the first storage device from the storage device to which the LDEV has been moved. By performing migration control in interlocking relation to control of access attributes, it is possible to obtain a simple data saving function and data management function.

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： A disk subsystem assures the sequence and the coherence of data updating with two or more disk subsystems is provided with an asynchronous remote copy function. A main center 9 includes a computer system having the configuration of slave subsystems 3-2 to 3-n connected with a master disk subsystem 3-1. It secures the coherence between data at the main center 9 and the remote center 10 at the temporary suspension by repeating temporary suspension and release of the temporary suspension of the remote copy by the master subsystem 3-1 at predetermined opportunities. It also repeats temporary suspension and release of the temporary suspension of the remote copy by slave subsystems 3-2 to 3-n connected to it.
