+#
+# === Parameters
+#
+# [*volume_backend_name*]
+#   (optional) The name of the cinder::backend::veritas_hyperscale ressource
+#   Defaults to $name.
+#
+# [*extra_options*]
+#   (optional) Hash of extra options to pass to the backend
+#   Defaults to: {}
+#   Example :
+#     { 'veritas_hyperscale_backend/param1' => { 'value' => value1 } }
+#
+# [*manage_volume_type*]
+#   (Optional) Whether or not manage Cinder Volume type.
+#   If set to true, a Cinde Volume type will be created
+#   with volume_backend_name=$volume_backend_name key/value.
+#   Defaults to false.
