+extends_documentation_fragment: openstack
+description:
+    - Reqeusts Ironic to set a node into inspect state in order to collect
+      metadata regarding the node. This command may be out of band, or in-band
+      depending on the Ironic driver configuration.  This is only possible on
+      nodes in 'manageable' and 'available' state.
+options:
+    mac:
+      description:
+        - unique mac address that is used to attempt to identify the host.
+      required: false
+      default: None
+    uuid:
+      description:
+        - globally unique identifier (UUID) to identify the host.
+      required: false
+      default: None
+    name:
+      description:
+        - unique name identifier to identify the host in Ironic.
+      required: false
+      default: None
+    ironic_url:
+      description:
+        - If noauth mode is utilized, this is required to be set to the
+          endpoint URL for the Ironic API.  Use with "auth" and "auth_type"
+          settings set to None.
+      required: false
+      default: None
+    timeout:
+      description:
+        - A timeout in seconds to tell the role to wait for the node to
+          complete introspection if wait is set to True.
