Vertica strongly recommends that the database be stopped prior to shutting down or rebooting the machine. If you need to shutdown or reboot the machine,
you should first stop the database from the web UI Administration->Database Status page.
If you are already logged into the Linux netqos account, you can stop the Vertica database from the Linux command line using the following command:
sudo /opt/NetQoS/scripts/doVerticaCmd.sh --shutdown
To start the Vertica database from the Linux command line:
sudo /opt/NetQoS/scripts/doVerticaCmd.sh --start
To check the status of the Vertica database from the Linux command line:
sudo /opt/NetQoS/scripts/doVerticaCmd.sh -status
Do NOT just power off the machine if you can avoid it.
