CMMVC9894E The command failed because VDisk is a clone or thin clone volume or is a snapshot VDisk.

Explanation
The volume is a thinclone or clone volume or a VDisk being used for a snapshot. Therefore the
split process would result in one of the copies being corrupt.

User response
Either remove the copy instead of splitting or for a clone wait until the population process is
complete before retrying the command.
