I am currently reimaging some old appservers to k8s workers as part of T351074 - in the last batch, two servers failed to reimage successfully: mw2369 and mw2367. The hosts get to the PXE boot stage in the BIOS and then fail to pick up a lease, eventually defaulting back into the currently installed OS.

This might be a re-run of T355333, but it is not a recurrence of the vlan/ip issues as seen in T357539 due to the rack position of the hosts.

I've done a racreset on the hosts and attempted re-imaging to no avail, please check network cabling etc. and firmware versions. Thanks!
