Cluster Node Configuration
Use the Cluster Node Configuration page to add or remove nodes from a failover cluster instance. Note that Setup operations for SQL Server failover clustering have changed in this release. To install or upgrade a SQL Server failover cluster, you must run the Setup program on each node of the failover cluster. To add a node to an exising SQL Server failover cluster, you must run SQL Server Setup on the node that is to be added to the SQL Server failover cluster instance. Do not run Setup on the active node.
SQL Server Instance Name - Use the drop-down list to select the SQL Server failover cluster instance to modify.
Name of this node - This field will be populated with the name of the computer that is running SQL Server Setup. This is the failover cluster node that will be added to or removed from the SQL Server failover cluster instance.
