[rdo-users] Add a pre-installed node

Hi everyone, We are trying to add a pre-installed node to our Overcloud, I've found this guide here: https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/... But we are using a CentOS deployment. All of the other nodes are already deployed with ironic (baremetal). Do you know if this procedure applies to our environment as well? Regards, Khodayar
