Changing controller identifier

NetApp93 — Mon, 15 Jul 2024 12:31:14 GMT

Good Morning all,

I feel like this problem is easily solved but im not sure about how to go about it the best way, or if im just overthinking it. Basically im building a new AFF-A150, and during the initial setup process I accidentally began with Controller B instead of Controller A, which made Controller B my "clustername-01" node. This isn't really a big deal but for the sake of uniformity across all my NetApp systems (all 2 node systems) i've wanted my clustername-01 node to be controller A and clustername-02 to be controller B. Would this be as easy as changing the LIF names for my 4 cluster SVM LIFS and 2 node management LIFS or is this something else I would need to do?

a bunch of easy steps.

First, rename the nodes

node rename clustername-01 clustername-02x (temporary)

node rename clustername-02 clustername-01

(rename cluster LIFs)

net int rename -vserver Cluster -lif clustername-02_clus1 clus1 (this will be fixed below)

net int rename -vserver Cluster -lif clustername-02_clus2 clus2 (this will be fixed below)

net int rename -vserver Cluster -lif clustername-01_clus1 clus1

net int rename -vserver Cluster -lif clustername-01_clus2 clus2

node rename clustername-02x clustername-02 (temp fixed here)

net int rename -vserver Cluster -lif clustername-02x_clus1 clus1

net int rename -vserver Cluster -lif clustername-02x_clus2 clus2

Then rename any mgmt LIFs

net int rename -vserver admin_svm -lif clustername-01_mgmt1 clustername-02_mgmt

net int rename -vserver admin_svm -lif clustername-02_mgmt1 clustername-01_mgmt

You sould rename the root aggrs (verify with aggr show)

aggr rename node02_root root_01

aggr rename node01_root root_02

If needed, rename any data aggregates for each node.

Yep, You'd just need to rename everything.
Nodes, LIFs etc.

Thanks sir! Figured it would be something like this. Appreciate you taking the time to write out the syntax 🙂
