    摘要: In a system comprising a first storage system providing plural first logical volumes including real logical volume and a virtual logical volume with a host, a second storage system having a second logical volume, and a management computer, when the first storage system receives an access request to the virtual logical volume, it accesses a second logical volume associated with the virtual logical volume. In this system, when the management computer receives a request to guard one of the plural first logical volumes, it checks whether a target first logical volume of the request is a real logical volume or a virtual logical volume, in case of the virtual logical volume, generates and provides a possible at least one option to guard the virtual logical volume by considering a program for volume guard, which each of the first storage system and the second storage system has.

    摘要: The present invention achieves data relocation in accordance with a user's policies, in an environment where a plurality of storage devices coexist. The volumes belonging to storage devices A-D are managed virtually integrally. A host recognizes a plurality of storage devices A-D as a single virtual storage device. The user is able to group arbitrarily each volume belonging to the storage system, as a plurality of storage layers 1-3. For example, storage layer 1 can be defined as a high-reliability layer, storage layer 2, as a low-cost layer, and storage layer 3, as an archive layer. Each storage layer is constituted by a group of volumes corresponding to respective policies (high reliability, low cost, archiving). The user designates volumes V1 and V2 to be moved, in group units, and indicates a storage layer forming a movement destination, whereby the data is relocated.

    摘要: There is provided a data migrating method including the steps of: calculating, in a case where data stored in a volume is migrated to another volume, a required period of time for migrating the data based on a size of data to be migrated and volume configuration information on the volume in which the migrated data is stored and the volume to which the data is to be migrated; determining a start time at which the data migration starts to generate a volume migration plan; setting a priority of the generated volume migration plan; prioritizing, in a case where a periods of time during which the generated volume migration plan is executed and a period of time during which an existing volume migration plan is executed are overlapped with each other, and changing the start time of at least one of those volume migration plans having a lower priority.

    摘要: In a computer system an object of this invention is to reduce physical resource contentions during the parallel migration of volumes. The computer system of this invention has the host computers, the storage systems and the storage management server. When parallelly migrating two or more volumes of data in the storage systems to the same number of other volumes, the storage management server selects volumes having few physical conflicts of the controllers or storage devices in the storage systems and executes the parallel migration operation.
