During a deployment, some drivers set the node.provision_state to WAITDEPLOY -- eg, while waiting for a callback from the deploy ramdisk agent. It should be possible to de-provision the node during this window (ie, clean up the files and network env, and power it off). This state is explicitly included in the check within do_node_tear_down:
https://github.com/openstack/ironic/blob/master/ironic/conductor/manager.py#L409
However, there's an API check which is preventing this.
https://github.com/openstack/ironic/blob/master/ironic/api/controllers/v1/node.py#L205
if rpc_node.target_provision_state is not None:
msg = _('Node %s is already being provisioned.') % rpc_node['uuid']
LOG.exception(msg)
raise wsme.exc.ClientSideError(msg, status_code=409) # Conflict
