摘要： A disk array apparatus that is capable of effecting saving and operation of data with 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： 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 method of selecting logical volumes that are the targets for data migration to equilibrate the load on a system, based on the accessing data of the physical drives and logical drives under the disk array controllers, without increasing the load of the disk array controller. An external manager communicates with two or more disk array controllers, gathers and manages the access data and the configuration data relating to the physical drives and logical volumes of each disk array controller, and prepares an optimum data migration instruction to equilibrate the access load.
