Hi! I tried searching to see if anyone else had successfully gotten FreeNAS configured to monitor multiple redundant UPSs, but couldn't find an answer. I was able to find the following information:
  • UPS configuration files are in /etc/local/nut
  • The files are created automatically on boot/service restart/service config by the /etc/ix.rc.d/ix-ups script (so directly modifying the files in /etc/local/nut will not work.)
I used the web UI to configure monitoring for UPS1, and it works fine. So no issues there. Tested and verified.

I was able to get UPS2 added to /etc/local/nut/ups.conf by simply adding some lines to the "Auxiliary parameters (ups.conf)" section in the UPS service configuration:
Code:
[ups2]
	driver = usbhid-ups
	port = /dev/ugen4.3
	desc = "UPS 2"


I stopped/restarted the UPS service and verified the changes showed up in ups.conf.

upsmon.conf was trickier, since there is no "auxillary parameters" section in the UI for that file. So I added a line to the ix-ups script:
MONITOR ups2 1 ${user} ${passwd} ${ups_mode}

I stopped/restarted the UPS service and verified the changes showed up in upsmon.conf.

I pulled the power cord on UPS1, and got *two* email notifications, indicating that both UPS1 and UPS2 were on battery. Only UPS1 was on battery. When I restored power, I again got two email notifications that UPS1 and UPS2 were "online".

I then pulled the power cord on UPS2, and no email notification was sent at all.

The console logs show the same thing. So I obviously have something configured wrong. I just can't figure out what it is.

/etc/local/nut/ups.conf:
Code:
[ups1]
	driver = usbhid-ups
	port = /dev/ugen4.2
	desc = "UPS 1"
[ups2]
	driver = usbhid-ups
	port = /dev/ugen4.3
	desc = "UPS 2"

	done
}

Any ideas on what else I need to change? My hardware setup is a Supermicro server with redundant power supplies. Each power supply is plugged into its own UPS. (Each UPS is plugged into a separate power circuit.) While it's unlikely that UPS2 would lose power without UPS1, it would be nice to have the monitoring working properly.

Aside from usb.conf and usbmon.conf man pages, I also read the "bigservers.txt" file where it describes configuring UPS monitoring for multiple redundant UPSs. (http://www.susaaland.dk/sharedoc/nut-2.0.3/docs/big-servers.txt) As far as I can tell, what I have should work.

Any help is greatly appreciated! Thanks!!

FreeNAS is only designed to monitor one UPS. Just monitor one and if it gets to low battery state shutdown the NAS.
Redundant power supplies are more about protecting yourself from a power supply failure and are usually plugged to the same power source, not to three separate UPS units.

I'm trying to do the same thing. Did you ever get nut/freenas to work with redundant UPSs?
