 RAID Support
 ^^^^^^^^^^^^
 
-The inband RAID functionality is now supported by iLO drivers.
-See :ref:`raid` for more information.
+The inband RAID functionality is supported by iLO drivers. See :ref:`raid`
+for more information.
+Bare Metal service update node with following information after successful
+configuration of RAID:
+
+* Node ``properties/local_gb`` is set to the size of root volume.
+* Node ``properties/root_device`` is filled with ``wwn`` details of root
+  volume. It is used by iLO drivers as root device hint during provisioning.
+* The value of raid level of root volume is added as ``raid_level`` capability
+  to the node's ``capabilities`` parameter within ``properties`` field. The
+  operator can specify the ``raid_level`` capability in nova flavor for node
+  to be selected for scheduling::
+
+    nova flavor-key ironic-test set capabilities:raid_level="1+0"
+    nova boot --flavor ironic-test --image test-image instance-1
