[Nut-upsuser] Multi UPS on Debian

Hello,

i have a server which supposed to control three Eaton UPS connected by USB
cables. Each UPS is Eaton NV 2000H. (eaton_1, eaton_2, eaton_3)
The connection is fine with each UPS, if it is configured alone. 
If i configure two or all three, the connections broke up.

After nut started, tried to start upsdrv manually (eaton_1. 
The log:

your issue is quite probably related to the USB matching system:
you well used the "bus" in configuration, but the port is something
totaly
arbitrary that is not taken into account for differentiating units...
thus, "eaton_2" and "eaton_3" are considered to be the same,
and the 2
drivers instances simply connect to the same one (ie the first found on Bus
4).
Which will result in drivers battling to get exclusive access on the device
(see the above "Got disconnected" messages).

To be able to differentiate these 2, you will have to change the Bus of one,
or to use the serial number (which is, when available, a better
discriminant), using "serial" in ups.conf.

cheers,
Arnaud

The eaton_2 and eaton_3 devices are not uniquely identifiable. The  
only thing that differentiates them in ups.conf is the port, but this  
is not used in the device matching (it will change on reconnecting the  
device, so it can't be used). Basically both the eaton_2 and eaton_3  
driver will attempt to connect to the same device (which will lead to  
a storm of connects and disconnects).

The recommended way to do use multiple USB devices, is to match the  
serial number of the UPS. This will make sure that if you plug the  
devices in a different port, the upsnames don't change. Check if the  
serial number is reported by the devices if you run the driver with  
the -DD option:

     /path/to/blazer_usb -DD -u root -a <upsname>

If it is, use that instead. Note that many generic USB to serial  
converters don't have unique serial numbers. In that case, your only  
option is to make sure they are on different busses and match those.  
If that isn't possible either, you can't control them from the same  
host.

Best regards, Arjen

PS  Unless needed, you shouldn't use the vendorid, productid and  
subdriver in ups.conf. Less is better here, since the additional  
matching that is required if you do is a waste of effort (matching  
regular expressions is expensive).

Hello Arjen,

as Armaud mentioned too, i'll have to change the bus-es. The UPS doesn't
give a serial.
I removed the unnecessary lines as you suggested.

Thanks for the reply and for the help!

cheers,
Csaba
