That is not an easy answer. In the world of UCS, there are several factors that can affect this:
1) Type of IOM (I/O Module) 2) Port config of the IOM (single link or port-channel) 3) Number of inks from the Fabric Interconnect to said IOM 4) Model of adapter in the blade. Depending on the combination of these things, it can be a 10, 20, or 40 GB link. On Wed, Jun 3, 2020, 9:40 PM Lee Trager <1881...@bugs.launchpad.net> wrote: > MAAS 2.7 introduced network testing.

Going to SSH in the middle of commissioning, running lshw shows all 10 NICs, and the disk of the proper size. This is causing the buckets.yaml for FCE to be inaccurate, and thus cannot write a bucketsconfig.yaml since the actual devices don't show up. This was tried with bionic {ga,hwe,hwe-edge} and focal ga kernels for commissioning, all have the same behavior. I was previously hitting this bug https://bugs.launchpad.net/maas/+bug/1878643 but applied the fix from comment #10, and am no longer getting any commissioning errors.
