Aria Automation 8.x
Automation services do not start automatically following an appliance reboot. By design, these services are automatically restarted only when powered on via Aria Suite Lifecycle Manager (LCM), and a manual reboot of the appliance via the console does not trigger the automatic startup of the application-level services.
To restore the UI and start the required services, you must manually run the deployment script.
/opt/scripts/deploy.sh
To cleanly reboot, it is recommended to Power off and Power on Automation via Aria Lifecycle manger, or stop the services, reboot and restart the services as per the documentation: https://techdocs.broadcom.com/us/en/vmware-cis/aria/aria-automation/8-18/vmware-aria-automation-on-prem-administering-8-18/maintaining-your-appliance/starting-and-stopping-vrealize-automation.html
