Description

Observation

The second link to new zen3 machine on OSD is down. The interface p3p1 is completely down.

According to dhcpd.conf:
host amd-zen3-gpu-sut1-2 { hardware ethernet b4:96:91:9c:5a:d4; fixed-address 10.162.2.133; option host-name "amd-zen3-gpu-sut1-2"; filename "pxelinux.0"; }

But ip addr show:

Steps to reproduce

  • ssh to amd-zen3-gpu-sut1-1.qa.suse.de
  • Collect network interface status

Problem

Down p3p1 could affect success rate of SR-IOV test

Suggestion

  • Make p3p1 interface up and running and make sure ip address configured

I just found the config file for the interface had been changed somehow to 'dot not boot automatically' I guess.

I changed it back to
BOOTPROTO='dhcp'
STARTMODE='auto'

Now p3p1 is up and running.

We just crosschecked https://racktables.nue.suse.com/index.php?page=object&tab=ports&object_id=16390 and found that the documentation covers this properly. Two interfaces are connected. For the next time like the tool ethtool can be of help to find out if there is a physical connection detected.
