    摘要: In a copy control method, during a process for the acquisition of a data copy at a designated time, a recovery period of time can still be reduced when an input/output request is issued for copy source data at the designated time. For a system that includes a first storage device in which data are stored, a second storage device that obtains a data copy, and a host computer that writes data to the first storage device, the second storage device obtains blank input/output requests that are issued at predetermined time intervals if the host computer does not generate an input/output request for the first storage device, and the second storage device determines that a time closest to a predetermined data copy acquisition time, which is a target time for the acquisition of a data copy, is a copy execution time for the acquisition of a data copy.

    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: Conventionally, when a switch virtualizing a storage (storage virtualization switch) is installed in a computer system including an SAN, a host computer, and a storage device, since a port ID of a virtual storage and a port ID of a storage device assigned to the virtual storage are different, the computer system has to be suspended at the time of installation of the storage virtualization switch. The storage virtualization switch installed in the computer system assigns a port ID to a port of a virtual storage generated by the storage virtualization switch so as to be equivalent to a port ID of an existing storage device and, in the case in which the port ID is designated as an access destination by an access request from one computer to the storage device, sends the access request to the virtual storage.

    摘要: An operation site has copy management information including state information that is used when executing a remote copy. The copy management information is stored in a storage device included in each of all storage device subsystems in this computer system. The copy management information is updated every time a remote copy is executed. When the operation site fails, by use of a copy management program in another operatable site, and with reference to the copy management information stored in the storage device of the storage device subsystem in each site, the copy is executed from a point to which the copy processing has progressed before the failure. As a result, when the production site in which an application is operated suffers from a disaster, it is possible to quickly recover data at the time of the disaster by executing a disaster recovery management program from another site in which no failure occurs, and then by restarting the remote copy.

    摘要: A storage system assigns a real area from a pool to a virtual area in a virtual volume, and stores data into the real area. The pool comprises a plurality of real areas based on a plurality of types of storage devices with different characteristics, and the plurality of real areas are managed as a plurality of tiers depending on the characteristics of the storage devices. Moreover, the storage system moves the data from one tier to another tier in the pool, for each real area.

    摘要: A backup is completed within a backup window designated by a user.When copying data in a first storage area, which is a backup target, to a second storage area, the capacity of a medium serving as a third storage area which is sufficient to complete a backup within the backup window, is calculated based on information about a differential bitmap describing an area in the second storage area to which the relevant data is copied from the first storage area, configuration information about a storage system where the storage areas are stored, and performance information about media constituting the storage areas; and differential data is copied using the second storage area and the third storage area; and the data written to the third storage area is copied to the second storage area.
