We have a 4 node cluster. 2 of the nodes have been recently added but we are having problems with snapmirroring since they were added.
The 2 new nodes aren't yet configured with an intercluster LIF as for various reasons we can't get those interfaces up and running. The snapmirror documentation makes it clear that every node in the cluster needs to have this for snapmirroring to work correctly. So now we are unable to configure new snapmirrors. The existing ones continue to work OK.
The 2 new nodes don't have any data on them so a quick fix would be to temporarily remove them from the cluster until we can get the interfaces for the intercluster LIFs connected. I don't really want to unjoin them as we would then have to reconfigure etc.
Is there a safe way to temporarily unjoin the nodes from the cluster so snapmirroring will work again?
Dumb question, but couldn't you just use a gigabit port if the 2 nodes have one that is regular CAT6/7 ethernet and run the LIF at gigabit speed? It sounds like it won't be used for replication anyway. That wouldn't require a SFP, and you can easily find a network cable.
