If you installed VCS and did not choose to configure VCS immediately, use the installvcs -configure option. You can configure VCS when you are ready for cluster configuration. The installvcs program prompts for cluster information, and creates VCS configuration files without performing installation.

The -configure option can be used to reconfigure a VCS cluster. VCS must not be running on systems when this reconfiguration is performed.

If you manually edited the main.cf file, you need to reformat the main.cf file.
