Changing Cluster Name and Physical Node Name for cDOT 9.1 Non disruptively

[Ontapforrum]

Hi,

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.

Thanks,

Ash

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 ?
