Before you can add an instance, the max instances parameter must have room for more instances, and a cluster-supported agent must run on the node on which you are creating the instance. You must know the host name and port number of the unified agent (UA).
Open the Server Instances folder in the left pane to display the server instances and options in the right pane.
Select Add Cluster Server Instance to open the Add Cluster Instance Server instance wizard.
Follow the steps in the wizard to add an instance to the cluster.
Click Finish. The new instance is listed under the Server Instances view.
Start the instance.
