Hi, I have included Ironic service into my rocky OpenStack platform. Using the IPMI driver. The cleaning network and the provisioning network are my provider network. I have some questions about Ironic deleting and inspecting. 1、every time I delete my baremetal nodes, I need to delete the associated servers first. the servers delete successfully, but the associated servers filed in nodes are still exist. So I need to set nodes to maintenance mode before I can delete bare metal nodes. what's more, the port list in 'openstack port list' which belong to the nodes can not be deleted automatically. How can I delete nodes correctly? 2、If the new created baremetal nodes' system disks have exist OS data.I cannot inspect them, I need to clean them first, but the cleaning step need MAC address of the nodes and the MAC addresses are obtained by inspecting. So what should I do? I don't want to fill in the MAC addresses manually. I have got the PXE boot but was immediately plugged into the existing system as: [image: image.png] 0.1s later: [image: image.png] Looking forward to your help. Ankele.
