Description

Hi Nick or Oliver or tools team,

amd-zen3-gpu-sut1-1 in OSD ipmi worker pool should have had 3 network connections as described in hcpd.conf, 1st for ipmi, 2nd for the master embeded network card 'em1', 3th for the secondary netword card 'p3p1'.

but we found 'p3p1' has no link detected. Could you please help to check the cable connection?

I connected p3p1, MAC b4:96:91:9c:5a:d4, to the port gi30 of the switch qanet02nue.qa.suse.de. I updated racktables in https://racktables.nue.suse.com/index.php?page=object&tab=ports&object_id=16390 with the connection and confirmed within the switch that the connection works as well as within the machine as I could login over SSH to amd-zen3-gpu-sut1-1.

EDIT: ethtool still shows no link detected, likely because the interface is not configured for network usage within the OS:

# ethtool p3p1
…
    Speed: 1000Mb/s
    Duplex: Full
    Auto-negotiation: on
    Port: Twisted Pair
…
    Link detected: no

The command ip link set dev p3p1 up changes that to "yes"

The journal shows:

Oct 17 04:25:57 amd-zen3-gpu-sut1-1 kernel: i40e 0000:41:00.0 p3p1: NIC Link is Down
Oct 17 04:26:01 amd-zen3-gpu-sut1-1 kernel: i40e 0000:41:00.0 p3p1: NIC Link is Up, 1000 Mbps Full Duplex, Flow Control: None

so the device should be usable now.

@Julie_CAO can you confirm this works for you?

Thank you, @okurz .

I just verified p3p1 has been connected and gotten it IP. Thanks for the quick fix.
