+Node Cleaning
+^^^^^^^^^^^^^
+The following iLO drivers support node cleaning -
+
+* ``pxe_ilo``
+* ``iscsi_ilo``
+* ``agent_ilo``
+
+Supported Cleaning Operations
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+* The cleaning operations supported are:
+
+  -``reset_ilo``:
+    Resets the iLO. By default, enabled with priority 1.
+  -``reset_bios_to_default``:
+    Resets BIOS Settings to default. By default, enabled with priority 10.
+    This clean step is supported only on Gen9 and above servers.
+  -``reset_secure_boot_keys_to_default``:
+    Resets secure boot keys to manufacturer's defaults. This step is supported
+    only on Gen9 and above servers. By default, enabled with priority 20 .
+  -``reset_ilo_credential``:
+    Resets the iLO password, if 'ilo_change_password' is specified as part of
+    node's driver_info. By default, enabled with priority 30.
+  -``clear_secure_boot_keys``:
+    Clears all secure boot keys. This step is supported only on Gen9 and above
+    servers. By default, this step is disabled.
+
+* For in-band cleaning operations supported by ``agent_ilo`` driver, see
+  :ref:`InbandvsOutOfBandCleaning`.
+
+* All the cleaning steps have an explicit configuration option for priority.
+  In order to disable or change the priority of the clean steps, respective
+  configuration option for priority should be updated in ironic.conf.
+
+* Updating clean step priority to 0, will disable that particular clean step
+  and will not run during cleaning.
+
+* Configuration Options for the clean steps are listed under [ilo] section in
+  ironic.conf ::
+
+  - clean_priority_reset_ilo=1
+  - clean_priority_reset_bios_to_default=10
+  - clean_priority_reset_secure_boot_keys_to_default=20
+  - clean_priority_clear_secure_boot_keys=0
+  - clean_priority_reset_ilo_credential=30
+  - clean_priority_erase_devices=10
