Removing Cluster Nodes - Switch Port Configuration

TMADOCTHOMAS — Wed, 04 Jun 2025 10:37:14 GMT

Hello,

We have a four node AFF cluster connected via a CN1610 switch. I am decommissioning two of the nodes in the next couple of days. After unjoining the nodes from the cluster, is there anything special that should be done in the switch config before disconnecting the cables from the CN1610?

Nope!

Just unjoin one node at a time.

When you are done be sure to enable HA. Needs to be enabled on a 2-node cluster

Thanks @TMACMD . I was under the impression that cluster ha would automatically be enabled when reducing down to a two node cluster. I did have in my plan to check for it but I expect it to change automatically. Is that not correct?

It may auto-enable, does not hurt to check!
