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： The data up to a point of time whereat failure has occurred will be restored at high speed at a remote site without imposing any burden on a host. The first storage system on the master side processes an I/O request from the host, and as a result of I/O processing to the second storage system on the remote side, transmits the update data. The second storage system retains data received from the first storage system as update log data. The host transmits a command for settling a state of an application to the first storage system as data, and the first storage system transmits the data to the second storage system. The host and the second storage system both retain an identifier corresponding to the command, and relate the identifier to the log data. Thereby, the host designates the identifier at any given time, whereby the second storage system restores the data at any given time.
摘要翻译：直到发生故障的时间点的数据将在远程站点高速恢复，而不会对主机造成任何负担。主机侧的第一存储系统处理来自主机的I / O请求，并且作为对远程侧的第二存储系统的I / O处理的结果，发送更新数据。第二存储系统将从第一存储系统接收的数据保留为更新日志数据。主机向第一存储系统发送用于确定应用状态的命令作为数据，并且第一存储系统将数据发送到第二存储系统。主机和第二存储系统都保留与该命令对应的标识符，并将该标识符与日志数据相关联。因此，主机在任何给定的时间指定标识符，由此第二存储系统在任何给定的时间恢复数据。

摘要： A migration destination storage creates an expansion device for virtualizing a migration source logical unit. A host computer accesses an external volume by way of an access path of a migration destination logical unit, a migration destination storage, a migration source storage, and an external volume. After destaging all dirty data accumulated in the disk cache of the migration source storage to the external volume, an expansion device for virtualizing the external volume is mapped to the migration destination logical unit.

摘要： System availability is improved in a second storage system, connected to a first storage system, and having means for virtualizing devices within the first storage system as its own devices. When the virtual storage system or a storage management server detects a fault in the virtual storage system, the management server investigates the range affected by the fault, identifies a device for which measures must be taken, determines a transfer target device which accommodates the performance, reliability, and other attributes of the affected device, and issues a device transfer instruction for the virtual storage system. In the virtual storage system, the data of the device specified by the instruction within the virtual storage system is transferred to a device, specified by the management server, within the system itself, or to a device within another virtual storage system.

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.
