Support for Mellanox MCX4121A dual 25G nic

[DerTom]

Hi!

In the german subforum I posted my question about my MCX4121A Mellanox card which seems to be 'unsupported'.

mstconfig q

Device type:        ConnectX4LX         
Name:               MCX4121A-ACA_Ax     
Description:        ConnectX-4 Lx EN network interface card; 25GbE dual-port SFP28; PCIe3.0 x8; ROHS R6
Device:             /sys/bus/pci/devices/0000:06:00.0/config

...

-E- Unsupported device

 

As I do not have an answer or a solution I kindly ask for your help also.

Is there a way to get this card working with unraid (6.12.6)?

I found this thread

 

where an MCX4121a is used also - I know it is the dual 10G, not the dual 25G... but there seems to be a way to get this working (driver modul!?)

I just don't know what and how to get this done...

Kind regards,

Tom

I had some help by ich777 - as I do use his plugin for MellanoxCards - and the solution was that I had to delete the network configuration files (network.cfg and network-rules.cfg from /boot/config).

Thank you!
