Abstract:
1. A method of managing more than two multi-volume copies in a storage management system recognizing a first multi-volume copy and a second multi-volume copy, each multi-volume copy holding at least one virtual volume, the first multi-volume copy and the second multi-volume copy listed in a control data set maintained by the storage management system, the control data set associating the first multi-volume storage device and the second multi-volume storage device with virtual volumes held thereon, the method comprising: directing at least one virtual volume from the first multi-volume copy to a receiving management class within the storage management system; exporting the at least one virtual volume to a third multi-volume copy based on the receiving management class, the third multi-volume copy unknown to the storage management system; creating a manifest file listing the at least one exported virtual volume, the manifest file separated from the control data set; determining that at least one of the exported at least one virtual volumes held on the first multi-volume copy is erroneous; unlinking the at least one determined erroneous virtual volume from the storage management system; and importing into the storage management system the at least one determined erroneous virtual volume from the third multi-volume copy.
