MANAGEMENT METHOD OF VIRTUAL STORAGE SYSTEM AND REMOTE COPY SYSTEM

摘要

Exemplary embodiments provide techniques of managing storage systems including remote copy systems and improving the manageability by automating complicated operations. In one embodiment, a computer comprises a memory and a controller. The controller is operable to: manage a virtual volume to be provided for a server; manage a plurality of logical volumes provided from a plurality of storage systems; manage a condition to be required of the virtual volume, the condition relating to a location in which data to be sent to the virtual volume is stored; manage location information of each of the plurality of logical volumes, the location information of a logical volume being defined based on a location of the logical volume; and control to map the virtual volume to a logical volume of the plurality of logical volumes, based on the condition of the virtual volume and the location information of the logical volumes.

主权项

1. A system comprising:
a plurality of storage systems including a primary storage system and a secondary storage system; wherein the primary storage system includes a primary volume having a primary local identifier; wherein the secondary storage system includes a secondary volume having a secondary local identifier which is different from the primary local identifier; wherein the primary storage system includes a primary storage controller operable, upon receiving a request to create a copy pair between the primary storage system and the secondary storage system, to confirm whether the copy pair can be created and, if yes, send the request to the secondary storage system; wherein the secondary storage system includes a secondary storage controller operable, upon receiving the request to create the copy pair between the primary storage system and the secondary storage system, to confirm whether the copy pair can be created and, if yes, to update a secondary storage pair information correlating the primary local identifier of the primary volume and the secondary local identifier of the secondary volume as the copy pair; and wherein the primary volume and the secondary volume have a same global identifier.
