Issues ixgbe

[zobrelaroca]

After trying several commands from Proxmox forum I broke ixgbe. Please help me to get it back.
Long story short, I have dual HBA I see it in Proxmox but SFP+ are not connecting.
On the switch showed connected but on Proxmox still down.

For a moment works but went I connected the second fiber never got back to work.
Please see the picture for the error also I can’t initialize ixgbe.

Checking modinfo ixgbe it reads that the allow_unsupported_sfp is (nowadays?) a boolean.

So if, it should be just a single 1 - not a 1,1.

FWIW, the module has also debug parameter which goes from 0 up to level 16, maybe try enabling that for more info if the change to allow_unsupported_sfp allone isn't enough to make it work.

Thank you I will try that.
This is the command that mess things up, I don’t know how to revert it.
How can I revert the following command?

echo "options ixgbe allow_unsupported_sfp=1,1" > /etc/modprobe.d/ixgbe-options.conf

The key information bit from your linked post is:

The OOT driver still has the option (I think it's not present anymore in the intree version).

Here OOT means Out-Of-Tree, which Proxmox VE doesn't use anymore (as intel recommends against using the OOT one).

How can I revert the following command?

echo "options ixgbe allow_unsupported_sfp=1,1" > /etc/modprobe.d/ixgbe-options.conf

As this wrote the options to a dedicated file with ixgbe as prefix it should be safe to just delete the whole thing:
rm /etc/modprobe.d/ixgbe-options.conf

Then either rmmod ixgbe && modprobe ixgbe to apply the settings, or if that errors or to be safe: reboot.

If you then later would want to try that option, but with the syntax supported by the now used in-tree driver, you could use a slightly adapted command:
echo "options ixgbe allow_unsupported_sfp=1" > /etc/modprobe.d/ixgbe-options.conf

Thank you guys!! What I mess I have

I removed the file --> rm /etc/modprobe.d/ixgbe-options.conf

dmesg |grep ixgbe

Do I have to reinstall the driver ?
