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.
