Did you install NUT from a package? Note, 2.6.5 is the current

I'm using the nut 2.6.3 package included in the openSUSE 12.2
distribution.
Check that your distribution's shutdown script is running
'upsdrvctl shutdown' in the presence of the killpower file
(POWERDOWNFLAG).
Summary: looks like an openSUSE bug, simple fix available.
OpenSUSE 12.2 has a script /usr/sbin/rcupsd for starting and stopping the
upsd service. This is a link to script /etc/init.d/upsd which contains:
powerdown)
## Special command: Instruct UPS to shutdown.
sync &
if grep -q '^\[' $UPS_CONFIG ; then
echo -n "Instructing UPS to powerdown "
$UPSDRVCTL_BIN shutdown >/dev/null 2>&1 || rc_failed
rc_check
else
echo "No local UPS defined, skipping powerdown "
fi
rc_status -v
;;
try-powerdown)
## Special command: Instruct UPS to shutdown, if halt is running
## or variable UPSD_POWERDOWN_CONDITION is set and power is failing.
## Otherwise silently quit.
##
if test "$RUNLEVEL" = "0" -o -n "$UPSD_POWERDOWN_CONDITION" ; then
if test -n "$POWERDOWNFLAG" -a -f "$POWERDOWNFLAG" ; then
exec $0 powerdown
fi
fi
;;
where UPSDRVCTL_BIN=/usr/lib/ups/driver/upsdrvctl
In addition, file /etc/sysconfig/shutdown contains the configuration
parameter
# Hook during system shutdown to run extra command
HALT_POWERDOWN_INSERT="/etc/init.d/upsd try-powerdown"
but when upsd try-powerdown is called it fails silently because $RUNLEVEL
and $UPSD_POWERDOWN_CONDITION are empty. upsd powerdown is never called.
I changed the configuration parameter to
HALT_POWERDOWN_INSERT="/etc/init.d/upsd powerdown", reran command
SuSEconfig, and tried again but there was no change. However typing the
command /etc/init.d/upsd powerdown does shut down the UPS unit.
OpenSUSE 12.2 has fully embraced systemctl and systemd: I tried grepping
around in the /lib/systemd shutdown specifications, but I cannot find any
reference to /etc/init.d/upsd powerdown. This is beginning to look like a
bug in openSUSE 12.2 which I will report in their forums.
Here is a fix: There is a file /etc/init.d/halt.local which is currently
empty:
# /etc/init.d/halt.local
# script with local commands to be executed from init on system shutdown
# Here you should add things, that should happen directly before shuting
# down.
I added the lines
# RP 2012-10-28 Turn off the UPS unit.
# Needed for automatic system restart when wall power returns.
UPSDRVCTL_BIN=/usr/lib/ups/driver/upsdrvctl
echo `date -I` `date +%T` "$0 calls $UPSDRVCTL_BIN shutdown" >>
/var/log/halt.local
$UPSDRVCTL_BIN shutdown
I pulled the plug from the wall and witnessed a server shutdown followed
10 seconds later by a UPS shutdown. Pushing the plug back into the wall
got the system running again.
