wikikube-ctrl1002 and wikikube-ctrl1003: Switch network cable from port 2 to port 1 on the 10G NIC
Open, Needs TriagePublic
Actions

Description

In T379629: wikikube-ctrl1001.eqiad.wmnet fails PXE boot we figured out that PXE boot does not work reliably when we use port 2 on the BCM57412.

We should switch from port 2 to port 1 because of this and to adhere to our general default.

After switching the port a cold reboot might be required so that the card does detect link. Also the BIOS settings need changing:

  • Ensure PXE is disabled on all embedded NIC ports
  • Ensure PXE is enabled on all 10G NIC ports
  • Ensure Port 1 is first in the boot order list (after Harddrive C:)

As the servers are in service and can't be taken down simultaneously, we need to coordinate a short maintenance window and do them one-by-one.

Please let us know what date(s) (and times) would work for you and we can prepare the first host accordingly or maybe find someone to be around for the process so we can do one after the other.
