CMMVC9936E The command failed because volumes have been added to the volume group since
when the snapshot was taken.
Explanation
When restoring an entire volume group from a snapshot the composition of
that volume group must match what it was at the time that the snapshot was taken.
User response
Reverse any changes (volume resizes, volumes added to / moved from the
volume group) that were made to the volume group since the snapshot was taken or use the
-volumes parameter to restore a subset of the volumes in the volume
group.
