I am sure changing Cluster & Node Name should be non-disruptive , but can someone who has done it or NetApp confirm the same ?
As far as SnapMirror is concenred, it happens via SVM, which which are not renaming at all.
We just want to change the Cluster Name & Node Name.
I am guessing, I will have to re-add the Cluster to : OCUM, as it was added via Hostname.
Changing cluster name can be done on the fly, it has no bearing on the sus-system tasks apart from it's Hostname entry in DNS and for OCUM.
However, I am concerend about the 'Node Name' change, as it has direct connection to Physical Disks, NDMP copy etc and any move opertion between Nodes ?
Can someone confirm it ?
