摘要： A method for configuring transparent synchronous mirroring volume switching for a first volume and a second volume that are coupled, via a storage area network, to a host computer, with the first volume mapped to the host computer, by. The method includes initiating synchronization of status data between the first volume and the second volume, and setting the first volume to an active state. The second volume is set to an inactive state, and an identifier associated with the active first volume is copied to a memory coupled to the inactive second volume. The copied identifier is retrieved from the memory by the host computer, and the inactive second volume is then mapped to the host computer.
