I have been troubleshooting why my server does not fully shut down when I tell Unraid to Shut Down, as when I did this the server would leave the Power LED on and would have to be physically power cycled by the switch on the PSU/unplugged from power in order to boot the server again.

 

I have now tracked this issue to Wake on Lan being enabled, I disabled it on eth0 (onboard 2.5G NIC) and then disabled it on the Asus 10G PCIe NIC which is eth1. I then checked that with WoL disabled on both NIC's it will properly shut down, which it does. However, every time I now tell Unraid to shut down or reboot, and I check "ethtool eth1" via terminal again, I find that it has again enabled WoL on eth1.

 

I've run "ethtool -s eth1 wol d" and that disables it, but as said only until you reboot. How do I get Wake on Lan permanently disabled on eth1?

Look in the BIOS, if there's no such option, you could have a user script doing that every boot.

I made sure that there are no options to wake set to enabled in the BIOS, I've checked again and in the meantime I added "/usr/sbin/ethtool eth1 wol d" to the "go" script and checked with "ethtool eth1" and saw "Wake-on: d" so assumed it was disabled, told unraid to shut down and it stayed powered again.

 

I have an AsRock Z790 Pro Rs ATX DDR5 (no WiFi) motherboard with an i9-12900k, and made sure that under Advanced > ACPI Configuration, PCIE Devices Power On was set to disabled, and I'm at a loss as to why it's staying powered.

This not relate WOL, the problem are PC fail to shutdown and power off, pls also note it even haven't reboot. It likely in HALT state.

 

Pls try boot in safe mode and then shutdown and feedback.

Safe mode or normal mode, the result is the same. The only "fix" seems to be enabling "Deep Sleep in S5" in the Chipset Configuration in the BIOS. I am absolutely certain that the server shut down perfectly to begin with when the Deep Sleep setting was "disabled" (which it is by default), and this behaviour started after enabling Wake on Lan for eth 1.

 

I still don't have an answer to the question of WHY Wake on Lan is not staying disabled when all I did to enable it was follow the instructions here:
https://docs.unraid.net/unraid-os/guides/wol-setup-for-unraid/

 

If running "ethtool -s eth1 wol g" permanently enables WoL, then by the same logic surely following the same instructions in reverse would permanently disable it? So why when I run "ethtool -s eth1 wol d" does it revert to "Wake-on: g" when I next reboot Unraid? Yes I can put code in the go script to be run at boot to disable it, but why should that be needed if it wasn't needed to enable it?

Sorry I miss that.

It should be normal, the setting won't permanently store in NIC's firmware. We don't need permanently, if mobo BIOS disable WOL then it won't wakeup even NIC WOL was enable, this shouldn't affect shutdown or anything.

 

I use WOL always and apply in different platform in Iongtime. I think problem need fix by new BIOS release.
