mchb command

Send the heartbeat related command.
You can issue the following commands: heartbeat configuration listing, heartbeat configuration, heartbeat modification, cluster name modification, and heartbeat port modification.

When you install MCCS, the initial user account ID is set to 'admin' and the password is set to 'password'.
