摘要： A host and a storage system each keep a shared identifier indicating a state of a system. The storage system acquires, at update of data, a data pair including data for a change through processing of the host and data before the update. The storage system relates the data pair to a shared identifier. When the host indicates an identifier, the storage system restores data using the data pair.

摘要： A storage system includes plural storage apparatuses storing data, and a storage controller which transmits and receives data between an external computer and the plural storage apparatuses, and further controls the plural storage apparatuses. Logical devices each representing a logical storage area are defined on the storage apparatuses. When one logical device is in a state of allocation to the external computer and stores data used by the external computer, and the logical device is deallocated from the external computer, the storage controller performs a processing such as erasing data from the logical device to be deallocated. The processing is performed according to the logical device being deallocated.

摘要： Data states of storage apparatuses are managed. When a storage apparatus is allocated from a storage pool to a computer, management information written in the storage apparatus is erased if the data state of the storage apparatus is unknown. When the storage apparatus becomes unnecessary and is restored to the storage pool, the management information is also erased. Further, when the storage apparatus is allocated to the computer, a level of confidentiality is set. When the storage apparatus is restored to the storage pool, data in the storage apparatus is automatically erased according to the set level of confidentiality.

摘要： The present invention provides techniques, including a method and system, for transferring data between computer systems, for example, a mainframe and a Personal Computer (PC), having storage systems of different formats, efficiently. One embodiment provides a method for transferring data from a first system, having a first processor and a first memory, using a first format to a second system, having a second processor and a second memory, using a second format. The method includes a first system receiving data of a first format from a first disk unit; processing the data of the first format into transformed data, where the transformed data is the data transformed into the second format; storing the transformed data in the first memory; and sending the transformed data from the first memory to the second system responsive to a request from the second system.

摘要： In the present invention, a management server manages, as virtual data areas, the physical data areas that storage devices have. Moreover, the management server includes a unit. Based on an access request received from each server, the unit issues, to the corresponding storage devices, an instruction of reading out the data onto caches from disks. Also, each storage device, which has received the instruction, includes each unit for reading out the data onto each cache in accordance with the instruction.
