I know how to change node name by issue
node rename -node old-name -newname new-name.
However, I also want to change cluster name.
What is the cli command?
SEE THE SOLUTION
I got it.
Here is what you need to do.
::>cluster create -license xxxxxxxxxx -clustername new-name
this is for Ontap version8.1.3
or... "cluster identity modify -name"
and to rename a host "system node rename -node currentname -newname newname"
