I have two new clusters to add to my search-peers. The original setup was a done a while ago, and by someone else, so this is a first for me. I see that I can add the cluster to the search-head via "Clustering-Add-Cluster-to-be-searched", but I also noticed that each of the individual servers was listed as search-peers under "Settings-Distributed Search". Do I add them to one, then the other? Or will adding the cluster automatically add the individual servers to the distributed search list?
If you're trying to let a search head search across its existing search peer's cluster and a to-be-added cluster, you should be able to add this new (to-be-added) cluster the same way you added the first one. You point it to the master node. I think this is what you're looking for: http://docs.splunk.com/Documentation/Splunk/latest/Indexer/Configuremulti-clustersearch
Clarify if I misunderstood?
Thanks Burch. I figured it out, and it worked as you described. I had never added a cluster to our existing search-heads, so this was a first.
