Thank you Rabi, but node import is mandatory or not? Bare Metal part is useful for power management and I'd like to maintain this feature.
AFAIK, the intent of using pre-provisioned nodes is to create an overcloud without power management control, among other things. Node import is not required when Tripleo(Ironic) is not doing the provisioning. I don't know if there are ways for Ironic to do power management of pre-provisioned nodes. Someone else may have a better answer.

Hi, I'm trying to deploy an overcloud using tripleo with pre provisioned nodes. My configuration is quite simple: - 1 controller and 1 compute nodes on which I already installed CentOS 8.2 - Both nodes have a dedicated idrac interface with an ip in 192.168.199.0/24. Please note that this interface is not visible with "ip a" or "ifconfig". It's a dedicated IDRAC interface - Both nodes have a NIC configured in the subnet 192.168.199.0/24 (192.168.199.200 and 192.168.199.201) - Undercloud uses 192.168.199.0/24 as pxe/provisioning network (but I don't need provisioning)
Question: should I import nodes with "openstack overcloud node import nodes.yaml" even if I don't need the provisioning step?
Furthermore, on the undercloud I created one file: /home/stack/templates/node-info.yaml with the following content
parameter_defaults: OvercloudControllerFlavor: control OvercloudComputeFlavor: compute ControllerCount: 1 ComputeCount: 1
Question: How can I specify that "node X with ip Y should be used as a
controller and node Z with ip K should be used as a compute"??
With pre-provisioned nodes (DeployedServer), you would need to specify HostnameMap and DeployedServerPortMap parameters that would map the pre-provisioned hosts and ctlplane ips.
Please check documentation[1] for more details.

Should I set the property with the following command? openstack baremetal node set --property capabilities='profile:control' controller1
Thank you, Marco
