    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 remote copy network realizes low-cost multi-hop remote copying. Remote copying is executed via a remote copy network (RCN) having a source edge device connected to a source storage and a target edge device connected to a target storage. Because the RCN is a network provided by a network business, a user having a storage device can execute remote copying without owning or managing the RCN. The source edge device receives remote copy I/O from the source storage, creates a log entry to which a sequential number is added, and sends the log entry to a target edge device. The target edge device acquires the remote copy I/O from the received log entry, and sends the remote copy I/O to the target storage in the order of the sequential number.

    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.

    摘要： In the conventional storage system, consistency is ensured only for writing from a single storage. Asynchronous remote copying and local replication are also alternately suspended in the conventional system, so that the suspension time increases and the volume in which consistency is obtained becomes old. Two local replicas are prepared, for a volume containing stored data that is transferred from the main site by asynchronous remote copying, in the storage at the sub-site. Each pair of local replicas is alternately suspended by a time-specific suspension command according to the time of the timestamp attached to the write data, and replica data in which the time sequence is secured is continually prepared. When a failure occurs at the main site, the data is recovered using the replica data.

    摘要： To provide a remote copy system including: a plurality of primary storage systems and a plurality of secondary storage systems; each of the secondary storage systems including a secondary logical volume that stores a copy of the data stored in a primary logical volume of the primary storage system; a pre-update data storage part that stores pre-update data that is stored before data to be stored in the secondary logical volume is updated and time stamps of the data to be stored in the secondary logical volume; pre-update data prior to a recovery time set based on the time stamps stored in the pre-update data storage part is obtained from the pre-update data storage part; and the pre-update data is written to the secondary logical volume in an inverse order of the time stamp with the latest time stamp first, to recover data of the secondary logical volume.

    摘要： In asynchronous remote copy, there is time difference between data update and remote copy in a primary storage system. The primary storage system loses data unreflected on a secondary storage system in disaster and cannot control the amount of data lost. The primary storage system obtains the data reflection state of remote copy between it and the secondary storage system to manage the amount of data update delay between the storage systems. When the amount of delay meets a configured start condition, a process of reducing the amount of delay is started. When the amount of delay meets a separately configured stop condition, the process of reducing the amount of delay is stopped. The configuration of whether the process of reducing the amount of delay is performed and the configuration of the conditions are performed from outside.
