I'm afraid you may be right, your UPS may not be supported by the
driver you use, because having a charge of 145% and a ups.load of 153%
is... quite strange ^_^
Mister, I am afraid I do not dare experiment with the UPS, forcing it into "LB" status.
Once already I had to replace my UPS because of wreck battery, so I do not want to risk it once
again. I really feel quite content with my system's power control now. The PC switches off 30 sec
after the power failure and the UPS is far from "LB" status at that time. It goes on
buzzing, but I think it is safe, for the power consumption from it is minimal. Am I not right? The
same would happen if my PC is off, there is nobody at home and the power fails: the UPS will start
buzzing until the power returns.
Yes, without the load of the PC, your UPS can buzz longer than with a
charge (obviously). But how many time... it depends on your UPS model.
It can be hours, or days. Normally, UPS should have a protection and
shutdown themselves if the battery is too low, but with some low price
model, there could not be such a protection. I cannot help you on this
point, try asking the manufacturer.
And if it happens that there are two short power falures one exactly 30 sec
after the other, my PC will shutdown. Ok, having in mind the possibility for
such a thing to happen, I do not find it quite annoying really :). Of course if
you do not see some significant potential problem in all that.
And concerning the UPS shutdown,
I remind you my notifyme script:
echo `date` >> /root/upsLog
echo " No power, shutting down the system!" >> /root/upsLog
sleep 30
control=`/usr/local/ups/bin/upsc [EMAIL PROTECTED] ups.status`
if [ $control != OL ]
then
/sbin/telinit 0
fi
I tried adding the line: "touch /etc/powerdown" to the "notifyme" script and
the lines:
if (test -f /etc/powerdown)
then
echo "Killing the power, bye!"
/usr/local/ups/bin/upsdrvctl shutdown
sleep 120
fi
to the /etc/rc.d/rc.6 script, but when I simulated a power failure, the system
shut down, but the UPS did not. I think I did not add the lines at the correct
place in the rc.6 script, or probably there is poor communication between the
UPS and the software, for I am not sure the software I am using is for my UPS.
In Slackware, rc.6 is the script that is executed when the system goes to
runlevel 0 or 6.
Besides, I am not quite sure whether I need to make the UPS itself go down in
case of power failure, because if it does not go down, it has the chance to get
charged when power returns.
So what would you recommend to me? Make the UPS itself power off after system shutdown in
case of power failure, or leave it buzzing till power returns? Remember, ny system is
configured to shutdown well before the ups.status becomes "LB".
In case you advise me to make the UPS go down itself after the system shutdown,
I will be thankful to you if you tell me if the method I suggest to achieve
that is working and where in the shutdown script I need to add it?
I never worked on the shutdown of UPSs, so I cannot help on this
point. As you said, it is either a mistake you made, that your UPS
don't support shutdown command or that the driver you use don't know
how to properly ask the UPS to shutdown (or maybe a mix of the three
^_^)
Perhaps someone that better know the shutdown process can help you
better than me.
Thank you for your responsiveness.
Regards,
Martin
