    摘要: A first storage system sets a storage area of a first disk drive as a first volume, and misrepresents an identifier of the storage system and an identifier of the first volume. A second storage system sets a storage area of a second disk drive as a second volume, and misrepresents an identifier of the storage system and an identifier of the second volume. The first storage system copies data of the first volume in the second volume. The second storage system copies data of the second volume in the first volume. A management computer determines whether there is a match between the data of the first volume and the data of the second volume. When it is determined that there is not match, the host computer accesses only one of the first volume and the second volume that stores the latest data.

    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: The present invention provides a means such that the related plural logical volume can be used after switching over from the host computer therein. A switching command which a host computer sends makes a storage device search the switching target volume, from the volume tables, that is identical to identification information of the switching target volume receipt among switching target candidate volumes that form the volume pair relation with the switching source volume, memorize the intra-host ID of the switching target volume and the intra-storage ID of the switching target volume after being searched in a switching table with corresponding there between, acquire the intra-storage ID of the switching target volume in reference to the switching table in case of receiving access request such that the intra-host ID of the switching source volume is a key and execute switching to access to the switching target volume.

    摘要: In A computer system, the processing load for the computer to acquire fault information from the storage system is reduced. The computer system includes a computer, a first storage system configured to be communicable with the computer, and a second storage system configured to be communicable with the first storage system. The second storage system identifies the first storage system that is capable of communicating with the second storage system, detects fault occurring in the second storage system, and transmits fault information to the identified first storage system, the fault information being related to the detected fault. And the first storage system notifies the computer of the transmitted fault information.

    摘要: A virtual machine system is constructed between a plurality of real machines of a multiprocessor system. In order to move a virtual machine operating in a virtual machine system on a given real machine to a virtual machine system on another real machine, each virtual machine system is managed by attaching a common logic name to the real machine resources. The origin of the virtual machine (VM) is notified of the logic name of the real resource corresponding to the VM configuration information. The destination VM includes a device for generating an identical VM configuration according to the logic name received thereby to realize the movement of the VM configuration. Also, the origin VM holds a new asynchronous operation request for the VM to be moved, and suspends the operation of the VM. The VM resource information and the asynchronous operation hold information are transferred to the destination. The destination VM restarts the VM operation in accordance with the received information.
