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: During the normal operation state of a computer system 1000, the data stored in a primary storage system 200P is copied to an intermediate storage system 200I via synchronous copying and the data stored in the intermediate storage system 200I is copied to a secondary storage system 200R via asynchronous copying. During the reverse operation state, however, the data stored in the secondary storage system 200R is copied to the intermediate storage system 200I via asynchronous copying and the data stored in the intermediate storage system 200I is copied to the primary storage system 200P via synchronous copying. In this way, practical remote copying can be carried out in a computer system in which three or more storage devices are installed at different locations and connected serially.

摘要: When plural copy groups including pairs exist, remote copying for pairs belonging to copy groups is suspended selectively on a copy group-to-copy group basis, instead of suspending remote copying in all the copy groups at once. A computer system has a host computer, plural first storage systems comprising plural first logical disks, and plural second storage systems comprising plural second logical disks. A first logical disk and a second logical disk paired with the first logical disk, and each pair belongs to either a first copy group or a second copy group. To selectively suspend remote copying on a copy group-to-copy group basis, one of the copy groups is specified first and then pairs belonging to this copy group are designated. The first storage systems comprising first logical disks of the designated pairs suspend remote copy processing for the designated pairs.

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: Availability of an information system including a storage apparatus and a host computer is improved. A host system includes a first storage apparatus provided with a first volume for storing data, and a second storage apparatus for storing the data sent from the first storage apparatus. In case of a failure occurring in the first storage apparatus, the host sends the data to be sent to the first storage apparatus to the second storage apparatus.
