+.SH NOTES
+If the Service Tags tool (from the sun-servicetag package) can be found in
+/opt/sun/servicetag/bin/stclient an inventory service tag will be created
+reflecting the Lustre service being provided.  If this tool cannot be found
+.B mount.lustre
+will silently ignore it and no service tag is created.  The
+.BR stclient (1)
+tool only creates the local service tag.  No information is sent to the asset
+management system until you run the Registration Client to collect the tags
+and then upload them to the inventory system using your inventory system account.
+See https://inventory.sun.com/ for more details on a web-based, free, IT asset
+management system.
