Metis driver failure to persist after host reboot
On some hosts, depending on their configuration, the Metis driver does not load automatically after a reboot. This guide makes it load on every boot.
Symptom
When the driver has not loaded, this command returns no output:
cat /sys/class/metis/version
Fix
Tell the host to load the metis kernel module automatically on every boot. You only need to do this once:
echo metis | sudo tee -a /etc/modules
After the next reboot, Metis is detected by lspci and the driver is loaded. Confirm with:
cat /sys/class/metis/version
Output
1.2.2
lspci -tv
Output
