    摘要: Transfer of data and replication of data among several storage devices are executed without imposing a load on the computer connected to the storage system. For example, a first host computer monitors usage rates of transfer groups TG11, TG12 and physical path usage rate on a storage device interconnect physical path 50, and when either a usage rate or physical path usage rate goes above a predetermined value, issues to the first storage device 20 an instruction to allocate a reserved volume Ri 1, R12. The first host adaptor 21 receiving the reserved volume Rh, R12 allocation request allocates reserved volume Ru to transfer group TGI, whereby a virtual transfer volume is formed by transfer volume Til and the reserved volume Ru allocated thereto. As a result, capacity of the virtual transfer volume is increased by the equivalent of the reserved volume Ru capacity, so that additional transfer frames may be stored.

    摘要: The computer system comprises a first and second computer, at least one first storage system connected to the first computer, and a plurality of second storage systems connected to the second computer as well as being connected to the at least one first storage system. The first computer issues to the first storage system a normal write request and control-use write request stamped with issue time. A control-use write request is issued at periodic intervals. The first storage system receives a write request and transmits the write request as update-data to second storage system in such a way that the issue order is ascertainable. The second storage system receives the update-data and, responsive to a reflect instruction from the second computer, reflects the update-data in storage areas. The second computer acquires the issued times stamped on update-data received by the second storage systems, establishes a standard time on the basis of issue times, and instructs the plurality of second storage systems to reflect the update-data whose issue time is at or prior to the standard time in storage areas.

    摘要: The object of the invention is to control the power consumption in a storage subsystem. In a storage system, when a monitor in a host computer acquires information concerning a storage region to manage the storage region, a monitor in the host computer checks whether or not the power supply state in the storage region is ‘on’ based on a storage region information that stores first information indicating whether or not the power supply state in the storage region is ‘on’ and second information concerning the storage region, and acquires the second information from the storage region information table if the power supply state in the storage region is not ‘on’.

    摘要: A controller sets a specified time which is a time that specifies a time in the future relative to the current time for all of one or more secondary storage systems. The respective secondary storage systems have a logical volume for backup (BVOL), and set a backup preparation end state when a journal up to a specified time has been established, and report information showing a preparation end state to the controller. The controller issues a backup command to all of the one or more secondary storage systems when information showing a preparation end state is reported from all of the one or more secondary storage systems.
