I'm trying to deploy Ironic using Devstack to use with hardware but I'm hitting a snag. 

++/opt/stack/ironic/devstack/lib/ironic:start_ironic_conductor:1731  openstack baremetal driver list

++/opt/stack/ironic/devstack/lib/ironic:start_ironic_conductor:1732  sleep 5
++/opt/stack/ironic/devstack/lib/ironic:start_ironic_conductor:1721  for attempt in $(seq 1 $max_attempts)
++/opt/stack/ironic/devstack/lib/ironic:start_ironic_conductor:1722  openstack baremetal driver list
++/opt/stack/ironic/devstack/lib/ironic:start_ironic_conductor:1722  grep -q idrac
++/opt/stack/ironic/devstack/lib/ironic:start_ironic_conductor:1726  '[' 7 -eq 7 ']'
++/opt/stack/ironic/devstack/lib/ironic:start_ironic_conductor:1727  die 1727 'Driver idrac did not appear in the driver list'

In local.conf: 

# Change this to alter the default driver for nodes created by devstack.
# This driver should be in the enabled list above.
IRONIC_DEPLOY_DRIVER=idrac

But there are several enabled lists above that line and apparently the driver list results in NULL. 

What magic bit am I missing? 

Thank you,
