How is this for a conundrum? I have three Tripp-Lite SMART5001U's running in the same one rack, attached to the same host running NUT. I am running the tripplite_usb driver thanks to some crafty hacking of Charles (thank you sir!). Now you may ask, "hey dip****, why have THREE 1U UPS's stacked up, when you can have a single larger one with the capacity of three?". Don't ask. I didn't build this stack of stupidity. I only have to support it!
But being that all of these buggers are identical ... I cannot get nut to tell them apart and so I can only monitor one of them at a time! Before I go writing a script that bounces between the three of them, is there a way I can get all three to work? It seems that I can use 'sudo /usr/local/ups/bin/upsrw -u pi -p pi -s ups.id=1 SMART500RT1U-1@localhost' to change the id (from the default of zero). But then when I load up the next one, nut says "oh, I remember this one ... it has an id of 1!". So it assigns '1' as the id of the second UPS, then dropping the first. UGH. Then I was looking at using the driver to try and change the serial number at load time, like this 'sudo /usr/local/ups/bin/tripplite_usb -u pi -a SMART500RT1U-2 -x serial=1' but I get an error, "No matching USB/HID UPS found". That tells me that the -x options are to help match a unit. Not to go changing the properties on the fly. Can anyone think of a clever way to make this work? The only thing that really defines these as different is the /dev/bus/usb value. So I would need some way of telling NUT to "fake it". :-) Steve Ballantyne Network Engineer MCSE/MCDST; Novell CLA; LPIC-1; CTT+; A+; Network+; Linux+; Server+; I-Net+; Security+; SonicWALL CSSA _______________________________________________ Nut-upsuser mailing list [email protected] http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/nut-upsuser
