# Perform configuration of the overcloud nodes' BIOS and RAID. Nodes should be
# registered with the seed's ironic service but not active. The BIOS and RAID
# is configured out of band using the ansible stackhpc.drac role. As such, only
# Dell servers with iDRACs are currently supported. During configuration, we
# set the ironic nodes' to maintenance mode to prevent ironic from managing
# their power states.
