One of the vCMP guests is not shown on the Guests Status Page. We have 2 Viprion Chassis configured in High Availability. Standby Chassis shows a complete guest status but not in Active Chassis.
Platform: Viprion C4800 | B4300
Software version: 14.1.5.5
If it is missing in status but actually defined, make sure you have it set to deployed. Otherwise, someone didn’t create it and well… you need to create it 
It is actually deployed.
Do you have partitions?
Does it show up via CLI ?
tmsh list vcmp guest
tmsh show vcmp guest
It might as well be this bug
This may help.
Is there any mitigation for this bug?
Not that I know of .. You should still be able to retrieve this information by CLI commands.
