The tpm restart command contacts the currently configured services on the current host and restarts each service. On a running system this will result in an interruption to service as the services are restarted.
The restart command can be useful in situations where services may not have started properly, or after a reboot services failed. For more information on explicitly starting components, see Section 4.2, “Starting and Stopping Continuent Tungsten”. For information on how to configure services to start during a reboot, see Section 4.3, “Configuring Startup on Boot”.
