I did that -- it works, **** many thanks ****.
There are various bits to this email, separated by ****.
/usr/local/ups/bin/upsc mintups at localhost ups.status
tells me:
OL CHRG
and when I unplug the UPS from the mains:
OB DISCHRG
If I go:
/usr/local/ups/bin/upsc mintups at localhost
I get:
battery.charge: 100
battery.runtime: 600
battery.voltage: 13
battery.voltage.nominal: 12
driver.name: usbhid-ups
driver.parameter.pollinterval: 2
driver.parameter.port: auto
driver.parameter.vendorid: 06da
driver.version: 2.3.0-r1014
ups.load: 25
ups.mfr: LIEBERT
ups.model: PowerSure Personal XT
ups.productid: ffff
ups.status: OL
ups.vendorid: 06da
and:
battery.charge: 95
battery.runtime: 600
battery.voltage: 12
battery.voltage.nominal: 12
driver.name: usbhid-ups
driver.parameter.pollinterval: 2
driver.parameter.port: auto
driver.parameter.vendorid: 06da
driver.version: 2.3.0-r1014
ups.load: 30
ups.mfr: LIEBERT
ups.model: PowerSure Personal XT
ups.productid: ffff
ups.status: OB DISCHRG
ups.vendorid: 06da
I don't see why ups.load goes up when I unplug it ?
****
Note that nut-2.3.0-r1014/scripts/RedHat/README is wrong, it should read:
Install ups in /etc/sysconfig/
/etc/sysconfig/ups is used only to store the POWERDOWNFLAG variable
Install upsd & upsmon in /etc/rc.d/init.d
Then run:
chkconfig --add upsd
chkconfig --add upsmon
If you have not already started the daemon & monitor, run:
service upsd start
service upsmon start
****
Under the default install directory of /usr/local/ups the PATH is wrong;
nut-2.3.0-r1014/scripts/RedHat/upsmon should be modified, before the line:
case "$1" in
Insert:
PATH=$PATH:/usr/local/ups/sbin:/usr/local/ups/bin
DO NOT change the PATH assignment at the top, since the PATH is reset
in /etc/rc.d/init.d/functions.
Alternatively the resetting of PATH can be done in /etc/sysconfig/ups
(as show later).
****
I modified nut-2.3.0-r1014/scripts/RedHat/upsd to allow UPSDCONF & UPSCONF
to be set in /etc/sysconfig/ups:
[ -z "$UPSDCONF" ] && UPSDCONF=/etc/ups/upsd.conf
[ -z "$UPSCONF" ] && UPSCONF=/etc/ups/ups.conf
(The default install puts them in /usr/local/ups/etc/)
Also add:
PATH=$PATH:/usr/local/ups/sbin:/usr/local/ups/bin
just below:
. /etc/rc.d/init.d/functions
Alternatively the resetting of PATH can be done in /etc/sysconfig/ups
(as show later).
****
Twice when I restarted upsd the system hung to 10 minutes or so. I have not had a chance
to investigate. Leave it alone & it came back.
System: CentOS 4.5 (==RedHat Enterprise 4.5), kernel 2.6.9-42.0.10.plus.c4, i386
Seems to be OK now ???
****
You need to mention somewhere that the firewall may need to be modified to allow
incoming connections to TCP port 3493.
****
I pulled the plug, got lots of warning messages about the thing being on
battery -- after a few minutes it decided to power down but never got there
as the UPS powered off before Linux had shutdown properly.
Plug the UPS back in and the machine came up without attention.
I have had a look at upssched ... looks complicated, why not just add
an extra parameters to ups.conf that 'fakes' an imminent power off
at the earliest of:
* X seconds of the UPS being on battery
* the battery.charge being less than Y%
* the battery.runtime less than S seconds
****
I attach a new patch against the current RedHat/CentOS 4.5 /etc/init.d/halt
This basically checks for /etc/killpower and if it is there executes:
upsdrvctl shutdown
I tested it by creating /etc/killpower by hand - it powers off;
unfortunately (in my testing) the machine then stayed off, even when
I unplugged/plugged in the UPS to the mains.
I would like the machine to come back up when power returns, I am
not convinced that this setup will do that.
****
I attach a patch against the current RedHat/CentOS 4.5 /etc/rc.sysinit
This removed the file /etc/killpower on system boot. Without doing
that 'upsdrvctl shutdown' would be called on every system reboot.
****
I attach my /etc/sysconfig/ups for your interest.
****
Cheers
