Hi all! I read this in the shutdown.txt:
Here are the steps that occur when a critical power event happens: 1. The UPS goes on battery 2. The UPS reaches low battery (a "critical" UPS) 3. The upsmon master notices and sets "FSD" - the "forced shutdown" flag to tell all slave systems that it will soon power down the load. But If I use my ups with nut on Battery when UPS don't send LB event just do Output OFF and kill PC and after itself. I don't understand when or why called the upsdrv_shutdown function? Please someone tell me what happens if UPS works on battery and I use NUT. Thanks your advice. 2010/7/9 Robert Jobbagy <[email protected]> > Hi Arjen! > > I attached the wrong and correct output , please check it. > The HEAD version liebert-esp2 driver give wrong output,but if you patch it > with my patch it will be correct. > In outputs.log focus on model,firmware,serial and mfr date values. > > And I attached my patch earlier. > > 2010/7/6 Arjen de Korte <[email protected] <nut%[email protected]> > > > > Citeren Robert Jobbagy <[email protected]>: >> >> >> I checked out the HEAD rev and tried the liebert driver. >>> it gave wrong model,firmware,serial, mfr date value. caused by len >>> variable >>> in line 97 and after >>> >> >> If you provide the debug output, this will save us looking up the last >> time you posted the results. >> >> >> I use my ups with usb -> serial converter. >>> >> >> Which one? >> >> >> these patches attached >>> >>> Did you try the liebert-esp2 driver in ON Battery mode ? >>> >> >> I don't have one, so I can't tell. >> >> >> Because If I switch my ups on battery (plugged off the input) then >>> liebert >>> driver force shutdown PC and shutdown UPS. >>> >> >> In it's present state, the liebert-esp2 driver can't shutdown the UPS. >> >> >> Battery is full charged.
