+--clientoptions <options>
+Additional options for Lustre.
+.TP
--config <arg>
Cluster configuration name used for LDAP query
.TP
+--conn_uuid <uuid>
+The failed connection (required for recovery).
+.TP
--d|--cleanup
Unconfigure a node. The same config and --node argument used for configuration needs to be used for cleanup as well. This will attempt to undo all of the configuration steps done by lconf, including unloading the kernel modules.
.TP
+--debug_path <path>
+Path to save debug dumps.
