Once we have added several servers to a cluster, server licenses becomes available for them. Licensing scheme requires the cluster to have at least one server included in the license to be running. Therefore, it is not necessary to include all the servers in the license right away. The number of servers can dynamically vary with time.
To activate a new server, go to Administration and click Show cluster servers in the Licenses section. The window displaying all the cluster servers, their tokens, and license statuses will open.
Copy the token and current registration key of the server you want to license.
Send the token and registration key to your sales rep to get the new activation key.
