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.
