CMMVC9921E The command failed because there is an existing FlashCopy mapping for the volume using
bitmap memory from a different I/O group.
Explanation
The I/O group of a change volume that is used for replication must be the same as
the I/O group used for any existing FlashCopy mappings.
User response
Remove and then re-create the FlashCopy mappings in the same I/O group as the
volume or relocate the volume to the I/O group that contains the existing FlashCopy
mappings.
