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… : []
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.
