CMMVC8926E The volume copy was not deleted because a change volume is providing the consistent image for a copy on the other site.
Explanation
An attempt was made to remove an image mode copy of a HyperSwap® volume while a change volume was still in use.
User response
Wait until the change volume is no longer in use, then retry the command. Alternatively, specify the -discardimage parameter to force the removal of the volume copy, which might result in data loss.
