Abstract:
An apparatus for configuring data migration comprises a host computer, a first volume, a second volume, a storage area network (SAN) configured to couple the host computer, the first volume, and the second volume, a memory coupled to the second volume, and a processor configured to map the first volume to the host computer; to copy a volume identifier associated with the mapped first volume to the memory, to retrieve, by the host computer, the copied volume identifier from the memory, to set a state of the second volume to inactive, to map the inactive second volume to the host computer, to set a state of the mapped first volume to inactive, to synchronize status data between the inactive first volume and the inactive second volume, after the copying, to start data migration from the inactive first volume to the inactive second volume, and after the starting, to set the state of the second volume to active.
