18.4 Using the application failover feature
Now that you have both NNMi management servers running the cluster manager, with one active server and one standby server, you can use the cluster manager to view the cluster status. The cluster manager has three modes:
Daemon mode: The cluster manager process runs in the background, and uses the ovstop and ovstart commands to start and stop the NNMi services.
Interactive mode: The cluster manager runs an interactive session in which the NNMi administrator can view and change cluster attributes. For example, the NNMi administrator can use this session to enable or disable the application failover feature or shut down the daemon processes.
Command line mode: The NNMi administrator views and changes cluster attributes at the command prompt.
