CMMVC6345E The repair operation cannot start because the space-efficient virtual disk (VDisk) copy was created using -import but the cluster could not recognize its format.

Explanation

You are attempting to repair a space-efficient VDisk copy that is reporting corrupt metadata. The cluster cannot repair the VDisk copy because it was not recognized as a valid space-efficient disk when it was imported into this cluster. The most probable cause is that the wrong MDisk was used when the VDisk copy was imported.
