CLM License Server idle standby deployment with CLM Licenses on 2 servers (Primary and Backup).
Jazz applications are licensed for use as single-server configurations and cannot be used in either a cloned or a clustered configuration, except if implemented in an idle standby configuration. In this configuration, you can activate a backup server if the primary server fails, or if maintenance needs to be performed on the primary server.
Note: You should be installing the exact same license file in the backup server, not a different license file, and you are entitled to activate the backup server when the primary server goes down, or when maintenance are needed for the primary server.
1) Configure the Licenses Server1 ( Primary Server) with permanent licenses (use the same license file)
2) Configure the Licenses Server2 ( Backup Server) with permanent licenses (use the same license file)
3) You can change the License server from Primary Server to Backup Server.
Note: The above configuration will avoid re-assigning of the licenses to the users, each time (Changing to backup server if the primary server fails)
