Open Stack

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:
(undercloud) [stack at interop010 ~]$ openstack baremetal port list
+--------------------------------------+-------------------+
| UUID                                                      | Address
    |
+--------------------------------------+-------------------+
| 2d404695-f236-4d32-8b65-5ca1fa6b756a | a0:36:9f:95:dd:e2 |
| 32669178-0408-4ff1-b4b4-df65fc7643c9 | 6c:ae:8b:69:ee:80 |
+--------------------------------------+-------------------+

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.
