  • [6.12.4] - Mellanox ConnectX-3 showing as down.

    Posted as a separate incident with diagnostics from main release thread.

     

    Upgrade from 6.12.3 to 6.12.4 appeared to go OK, but I have a network card issue.

    I have a 10gb fibre card, and onboard 1gb nic. These are set to a bond and it mainly uses the 10gb (onboard is enabled for WOL - a script after waking forces the 10gb card to be active).

     

    My fibre card is constantly showing as disconnected (Interface Ethernet Port 1 is down. Check cable!) . Changing designations between eth0 and eth1 makes no difference.

    It is listed in system devices as

    [15b3:1003] 02:00.0 Ethernet controller: Mellanox Technologies MT27500 Family [ConnectX-3]

     

    The new system drivers shows two drivers:

    mlx4_core    Mellanox ConnectX HCA low-level driver    Inuse    net/ethernet/mellanox/mlx4
    mlx4_en    Mellanox ConnectX HCA Ethernet driver    Inuse    net/ethernet/mellanox/mlx4
     

    I have the Mellanox Firmware Tools installed -  which seems to report the card OK.

     

    Anyone else with this issue?

    I also have a Mellanox X3 and it runs under 6.12.4 without any problems (update from 6.12.1).

    No issues for me as well, updated two servers with ConnectX-3 so far, might also be a good idea to reboot the switch, if one is in use, I sometimes need to do that after a reboot to get the link back, if not try to roll back to 6.12.3 and confirm it still works.

    Rolled back and it was still not working, but I didn't do a restore

    Tried swapping "cable" but it didn't make a difference.

    Could be something failing at a bad time, so have taken the card out and will try it in another machine soon.

    Not keen on rebooting the switch as it's POE and have quite a few devices hanging off it. I haven't tried swapping ports on the switch.

    Seems like it might not be a 6.12.4 issue specifically.

     

    Thanks for suggestions and support @JorgeB & @andber
