Hello Julia, Thanks for your response.

I am using a RedHat Openstack Platform 16.1, which is running on RHEL 8.2.

All are physical servers;

- One Undercloud Director.

- Overcloud consists of two nodes. (This is for Certification purposes)

It is unlikely that it's a mac addr. mismatch (I wish...) since I've already deployed these nodes several times, using the same nodes.json

Just for reference , here is the output:

The operation was working well until I have 'lost' the undercloud node, but overcloud stayed working.

I might need to delete these nodes and run introspection again.

So versions and overall configuration might help, *but* often these
issues are just a typo with a MAC address or the wrong port. Can you
verify that the MAC address your seeing DHCP requests for matchs what
is recorded for the node in the `openstack baremetal port list`
output?
