2. If your prism central VM is powered off, then power on first


3. If your prism central VM is deleted, you can delete the multicluster state and wait for new state to be created.

in one of your CVM:

ncli multicluster get-cluster-state

copy cluster-id:

[sourcecode]
Cluster Id : xxxnxnxnxn-xnxnxmx-xmnxmxmx-xjxmxmx
Cluster Name : Unnamed
Is Multicluster : true
Controller VM IP Addre... : [1.1.1.1]
External or Masqueradi... :
Controller VM NAT IP A... :
Marked for Removal : false
Remote Connection Exists : true
[/sourcecode]

then delete the state:

ncli multicluster delete-cluster-state cluster-id=xxxnxnxnxn-xnxnxmx-xmnxmxmx-xjxmxmx

xxxnxnxnxn-xnxnxmx-xmnxmxmx-xjxmxmx is your cluster Id.
