摘要： A storage subsystem that has detected the necessity of the data relocation determines whether the data relocation is possible or not from one storage unit to another within the particular storage subsystem. A virtualization device is notified in the case where the data relocation in the particular subsystem is impossible. The manager of the virtualization device gives an inquiry to the storage subsystems as to whether any one of them can become a relocation destination or not. A storage subsystem determines, based on the related information, whether the data relocation requested is possible or not within the particular storage subsystem. In the case where such a relocation is possible, the copying process is carried out for data relocation from one storage subsystem to another in compliance with an instruction from the virtualization device.

摘要： The present invention provides a method for guaranteeing a data consistency among a plurality of storages and sites, when data transfer is performed by asynchronous remote copying from a site including a plurality of storages. When writing is made into a first storage system or a second storage system, the storage system that received the writing transfers the write data to the other storage system within the site by synchronous remote copying. At this timing the first storage system gives the write data information for order assurance. Furthermore, the first or the second storage system transfers the write data and thus given information for order assurance to the third or the fourth storage system by asynchronous remote copying. Furthermore, the third or the fourth storage system which has received the write data transfers to the other storage system within the same site the write data and information for order assurance by synchronous remote copy.

摘要： When a logical volume in a first storage box is transferred to a second storage box, information of an access object such as a network communication protocol possessed by a host which communicates with the first storage box is changed to change a network route for accessing the transferred logical volume. Logical volume transfer is notified from the first storage box to the host by using an ICMP Redirection Error message or the ARP protocol.

摘要： A storage unit is provided which is connected to a host computer through a network, having one or more disks in which read and write operations are performed during rotation and a control unit for controlling the rotation of the disks. In the storage unit, when receiving a message which is sent from the host computer and predicts that at least one of the disks will come in use, the control unit causes the at least one of the disks which will come in use, to rotate.
