CMMVC6312E The command failed because the target VDisk is the source of a FlashCopy mapping that is in the specified consistency group.

Explanation

A particular VDisk cannot be both the source of one FlashCopy mapping and the target of another FlashCopy mapping in the same consistency group. The FlashCopy mapping was not created because the target VDisk of the FlashCopy mapping that you attempted to create is already the source VDisk of a FlashCopy mapping in the consistency group that you specified.
