Enabling the MySQL autostart setting

You should ensure that the autostart feature is turned on for the MySQL deamon. Turning on the MySQL daemon automatically restarts MySQL if the system on which the MetroCluster Tiebreaker software resides reboots. If the MySQL daemon is not running, the Tiebreaker software continues running, but it cannot be restarted and configuration changes cannot be made.

See the MySQL documentation to enable autostart on your installation.
