I have an ups connected via usb with my omv-server. I have installed the NUT-Plugin and it's great! I have set that in case ups goes on battery mode the nas is safely shutdown in 15 seconds.
I would like that the omv-server also automatically-restart when (and only when) power is restored (ups return in normal mode). How can I do that?
Browsing the internet I've read that I should set the Power Restart Option in the BIOS on "Always On". Is the correct way? I suspect that if I set "Always On" in case of power failure the omv-server is safely shut down after 15 seconds but if the power outage is persistent with this option the server is restarted with the ups still in battery mode and I don't want it.
