Abstract:
Systems and methods described herein involve a virtual storage utilized to virtualize the storage of storage systems across multiple sites. The virtual storage is associated with a virtual multipath control. The virtual multipath control manages the virtual path state of the inter-physical storage, the remote copy volume state which has primary volume or secondary volume state, and the volume copy operation mode such as synchronous copy mode journal copy mode, or bitmap resync mode. The virtual multipath control of the virtual storage facilitates choices from the host for a preferred site, path, state, and volume by utilizing a virtual multipath state from a get virtual multipath information command.
