How to remove a node from an existing failover cluster (Setup)
- On the Welcome screen of the Microsoft SQL Server Installation Wizard, click Next.
- On the Computer Name screen, click Virtual Server and specify the name of the server from which to remove the node. Click Next.
- You may see an error message saying that one (or more) of the nodes of the Microsoft® Windows NT® 4.0 or Microsoft Windows® 2000 cluster are unavailable. This may be because the node(s) you are attempting to remove is damaged. The node(s) still can be removed. Click OK.
- On the Installation Selection screen, click Advanced Options. Click Next.
- On the Advanced Options screen, click Maintain a virtual server for failover clustering. Click Next.
- On the Failover Clustering screen, click Next.
You do not need to modify any IP address(es).
- On the Cluster Management screen, select the node and click Remove. Click Next.
- On the Remote Information screen, enter login credentials for the remote cluster node that has administrator privileges on the remote node(s) of the cluster. Click Next.
- On the Setup Complete screen, click Finish.
If you are instructed to restart the computer, do so now. It is important to read the message from SQL Server Setup when you are done with installation. Failure to restart any of the specified nodes may cause failures when you run the Setup program in the future on any node in the failover cluster.
