    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.

    摘要: A storage device control method for operating a logical volume to which a control command cannot be issued directly from a host computer is provided. The host computer manages a storage device. The storage device includes a disk device which provides logical volumes and a disk control device which controls the disk device. The host computer issues a control command to a recognized volume in the disk control device. The disk control device operates a recognized volume which is an issue destination of the control command or an unrecognized volume contained in the control command. A logical volume to which the control command is to be issued from the host computer is determined by using definition information (a disk information table, a copy pair information table, or a copy group information table) concerning copy operation retained by storage control software which operates on the host computer.

    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 R11, R12. The first host adaptor 21 receiving the reserved volume R11, R12 allocation request allocates reserved volume R11 to transfer group TG1, whereby a virtual transfer volume is formed by transfer volume T11 and the reserved volume R11 allocated thereto. Capacity of the virtual transfer volume is increased by the equivalent of the reserved volume R11 capacity, so that additional transfer frames may be stored.

    摘要: In a computer system, to enable a second computer to take over control of copying of data within the computer system, from a first computer that normally controls copying of data.The second computer selects from a plurality of storage systems a storage system to be accessed in order to acquire sub system pair information, and acquires sub system pair information from the selected storage system. Based on the acquired sub system pair information, the second computer generates system pair information that includes copy pair information relating to a plurality of storage areas belonging to the plurality of storage systems. The second computer initially selects a storage system directly linked to the second computer, and subsequently sequentially selects a storage system based on the acquired sub system pair information.
