Nut upsuser - Mar 2007 - Starting Network UPS Tools: (upsdrvctl failed) upsd upsmon ?

Using the HOWTO in
http://keystoneit.wordpress.com/2006/09/25/network-ups-tools-nut-on-ubuntu/
I installed nut on an Ubuntu Edgy LAMP Server with an Eaton Powerware 5110
attached to it via usb. But nut fails to start properly (see the error
message "Starting Network UPS Tools: (upsdrvctl failed) upsd upsmon"
below). It then complains about communication with the UPS being lost
("UPS upsl@localhost is unavailable").

I wonder whether this communication error message may be related to the
howto assuming that a user 'upsl' exists, while 'nut' only
configures a
user 'nut'. I am new to 'nut' so any hints are welcome. I have
no clue why
upsdrvctl fails when I start nut when it first starts properly by itself.
Below I included the configuration files (found in /etc/nut/*)
Please advise me on how to deal with both these issues.


# upsdrvctl start
Network UPS Tools - UPS driver controller 2.0.4
Network UPS Tools - BCMXCP UPS driver 0.10 (2.0.4)

Model = POWERWARE UPS    1000VA
Firmware = 00.50
Shutdown delay =  120 seconds
Shutdown delay longer than battery capacity when Low Battery warning is
given. (max 60 seconds)
# /etc/init.d/nut start
Starting Network UPS Tools: (upsdrvctl failed) upsd upsmon.

No. It will complain in case of permissions problems, but this is not what
is happening here.

You can't start a driver multiple times for the same UPS. So if you ran
'upsdrvctl start', the script '/etc/init.d/nut start' (that will
do so
also) will fail. You need to run 'upsdrvctl stop' first, if the driver
is
running already for whatever reason.

You may want to upgrade to the latest stable version (2.0.5), although
this doesn't seem to be related to the problem you're having.

See above. This script attempts to start the UPS driver through
'upsdrvctl', but since it is already running, this fails. A well behaved
startup script would check for a successful startup of the driver and
would have terminated here. Why it isn't, is beyond me.

Hi Theo,

You can try to run the driver only with the ups.conf.

Locate the bcmxcp_usb driver. then run this command.

/path/to/bcmxcp_usb -DD -a powerware

(exchange the /path/to with the right path)

Now it should spit out som debug info if the communication is ok.

You should also upgrade to the 2.0.5 version as (think it was) Arjen
found one bad typo in the shutdown functions. Also you should set
the shutdown_delay to 60 in the ups.conf as it warns that it could
not run more than 60 sec after it signaling low battery.

This time is used to power off the ups after a low battery warning.
So it should give a shutdown -h now on battery low, then run for 60 sec
and power off. Normal a machine should manage to go down to halt in this
time. But with 2.0.4 it would not power off (se above).

Regards
Kjell
