摘要： A remote copy system includes a plurality of first storage systems and a plurality of second storage systems. Each first storage system assigns a sequential number to write data received from the host and sends the write data with the sequential number to the second storage system. One of the first storage systems defers the processing of the write request received from the host and instructs each of the first storage systems to create a marker, whereupon each of the first storage systems defers the processing of the write request, creates a marker including a sequential number and having a marker number, and sends the marker to the second storage system.

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： During an asynchronous remote copy process for a plurality of asynchronous remote copy pairs, a copy of data in a migration source primary storage area is stored in a migration destination primary storage area, and the copy of data in the migration source primary storage area is also stored in a migration destination secondary storage area through a migration destination primary storage area or a migration source secondary storage area. Then, for an asynchronous remote copy pair established between the migration destination primary storage area and the migration destination secondary storage area together with the above-described asynchronous remote copy pairs, the asynchronous remote copy process is executed in such a method that a copy of writing data is stored in a plurality of secondary storage areas in accordance with the write request sequence issued by a computer. As such, an asynchronous remote copy pair between any two specific storage systems is migrated to be an asynchronous remote copy pair among any other two storage systems.

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： Even when a host does not give a write time to write data, consistency can be kept among data stored in secondary storage systems. The present system has plural primary storage systems each having a source volume and plural secondary storage systems each having a target volume. Once data is received from a host, each of the plural storage systems creates write-data management information having sequential numbers and reference information and sends, to one of the primary storage systems, the data, sequential number and reference information. Each of the secondary storage systems records reference information corresponding to the largest sequential number among serial sequential numbers and stores, in a target volume in an order of sequential numbers, data corresponding to reference information having a value smaller than the reference information based on the smallest value reference information among reference information recorded in each of the plural secondary storage systems.

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.
