>> With respect clarification of the documentation (and reference to your
question Charles). The documentation does suggest that you can shutdown the
ups by the upsdrvclt shutdown [ups] command. Specifically in "
http://www.networkupstools.org/docs/man/upsdrvctl.html" in the section
commands under warning. In the "Network UPS Tools User Manual" (pdf) under
section 6.3.2 in the last paragraph it is suggested to first test
the /usr/local/ups/bin/upsdrvctl -t shutdown and then "upsmon -c fsd". Also
this section suggests that under some circumstances you cannot rely on the
shutdown sequence to issue this command.

that I  already tested the setup with the "upsmon -c fsd". The results is
that the server closes down, as expected, but ups does not shutdown, and so
there is no restart of the server.
>> I was guessing it has to do with the particular shutdown command of the
server I have, which was "SHUTDOWNCMD "/usr/lib/web-admin/backend.pl
And I was trying to fix that by calling the upsdrvctl shutdown command
directly from a script.
>> As I do not use the packaged (debian) shutdown script (/sbin/shutdown)
do I need to tell the ups to power down myself, as   suggested in  the
documentation (configuration notes, see reference above)?
> I haven't traced through the Debian shutdown sequence recently, but I
think that they call "upsdrvctl shutdown" after the rest of the system
processes have shut down (including the NUT driver). That should avoid the
"device or resource busy" error - only one process can open the UPS USB
device node at a time.

Thanks for all your help, regards Louis
