[Users] Proper way to reboot an ovirt node

What is the recommended proper way reboot an Ovirt node ? I started by putting the host into in Maintenance mode and was going to via the TUI interface just reboot the machine. Should I then use the "confirm host rebooted" before I put the host back from Maintenance mode ? I have rebooted my Nodes violently hundreds of times (and they have always recovered), but now I have data/config that I'm keen not to loose. Failed to find this info on the wiki... Brgds Jonas
