It will be very seldom but if you need to remove a Nutanix cluster from PRISM central it is very easy (no big surprise when you know Nutanix)
Login to PRISM central, select “Explore”:
Select “Clusters” on the left. Select the cluster which has to be removed on the right side:
from the “Actions:” menu select “Unregister Cluster”:
If you are sure then select “Yes” and you are done!
Wait some minutes and the elements from the cluster will disappear from Prism central.
Woah, that was very easy again…
Pro tip: The clustered doesn’t need to be online for the removal task.
but wait! what if I have no prism central anymore and I want to remove the PC registration from my Prism Element?
- Just login to one for your CVMs and start ncli and get the cluster ID:
ncli> multicluster get-cluster-state
Cluster Id : 66940754-1ab8-4447-a758-a30396f1c997
Cluster Name : Unnamed
Is Multicluster : true
Controller VM IP Addre… : [10.2.4.155]
External IP Address :
Marked for Removal : false
Remote Connection Exists : true
- then you can delete the registration entry for this cluster:
ncli> multicluster delete-cluster-state cluster-id=66940754-1ab8-4447-a758-a30396f1c997
- now the cluster is released from the PC registration.
