Hi,
I read some posting on removing a node in SQL cluster. I have never done it, and still have some questions.
I have a three nodes active-active-active SQL 2008 R2 cluster environment. Node A, Node B and Node C. Normally the setup is like the following: Node A has DB1, Node B has DB2, Node C has DB3. When needed, DB1 can fail over to any other 2 Nodes, so do DB2 and DB3.
Now Node A has DB1, Node B has DB2 + DB3. I need to remove Node C from the cluster, but still keep the DB1, DB2 and DB3 running on Node A and Node B.
Do I run the SQL setup.exe and go to Maintenance, remove a node? If yes, during the processes, on the Cluster Node Configuration page, specify the name of the Node and the instance name, in my case, it'd be Node C, what about the instance? My concern is if I choose DB3, then it would uninstall the DB3. I only want Node C to be removed from the cluster and keep all the instances.
Thank you in advance.
