DOC: 5.4. Defining the Root Disk for Nodes - steps no longer work


Version-Release number of selected component (if applicable):
RH OSP 8

How reproducible:

After invoking on udercloud:
for uuid in `ironic node-list | awk '{print $2}'`; do echo "Node ID: $uuid"; ironic node-show $uuid | grep 'properties\|extra ' -A3; done

Expected results:
This used to work in RHEL OSP 7

Additional info:
