Summary:PROBLEM TO BE SOLVED: To enable a host to modify the configuration of a remote data facility (RDF) by automating a process for changing the RDF configuration. SOLUTION: A method for accessing mirrored data after reversing a communication path between a first volume on a first storage device and a second volume mirrored on a second storage device has permitting access to the mirrored data prior to the synchronization of the data, accessing the mirrored data on the first volume if the initial version of the data is on the first volume, accessing the mirrored data on the first volume if the initial version is on the second volume and the initial version has been copied from the second volume to the first volume, and accessing the mirrored data on the second volume.
