This is not a NUT question per se ... or at least, I don't think it is. I just replaced the battery pack in my HP R3000XR; the new batteries were shipped with 90% charge, were at about 87% when they went in, and were up to 98% charge the next day.
Last weekend, the server that runs NUT went down for no apparent reason, wiping out its boot blocks, corrupting its boot archive beyond repair, and forcing an OS reinstall. After reinstalling Solaris 10, NUT is now reporting battery charge hovering between 40% and 42%. This is puzzling, considering that it initially reported full charge, the UPS is only under about 40% load and, the power has not gone out. babylon4:root:~:3 # upsc tokamak ambient.temperature: 34.5 ambient.temperature.high: 55 battery.charge: 40.2 battery.runtime: 440 battery.voltage: 130.0 device.mfr: Eaton device.model: COMPAQ UPS 2900i device.serial: ??MPAQ device.type: ups driver.name: bcmxcp driver.parameter.baud_rate: 19200 driver.parameter.pollinterval: 2 driver.parameter.port: /dev/tty00 driver.version: 2.4.3 driver.version.internal: 0.23 input.current: 12.1 input.frequency: 59.8 input.frequency.high: 65 input.frequency.low: 55 input.frequency.nominal: 60 input.transfer.boost.high: 12 input.voltage: 119.5 input.voltage.nominal: 120 outlet.1.delay.shutdown: -1 outlet.1.delay.start: 1 outlet.1.id: 1 outlet.1.status: On outlet.2.delay.shutdown: -1 outlet.2.delay.start: 2 outlet.2.id: 2 outlet.2.status: On outlet.3.delay.shutdown: -1 outlet.3.delay.start: 3 outlet.3.id: 3 outlet.3.status: On output.current: 10.3 output.current.nominal: 24.0 output.frequency: 59.8 output.phases: 1 output.voltage: 115.3 output.voltage.nominal: 120 ups.beeper.status: enabled ups.firmware: Cont:01.01 ups.load: 41.4 ups.mfr: Eaton ups.model: COMPAQ UPS 2900i ups.power: 1191.5 ups.power.nominal: 2900 ups.serial: ??MPAQ ups.status: OL Does anyone with more experience with NUT or with this UPS model than I know whether there's any kind of calibration I need to do after replacing the battery pack, or have any idea why the UPS would have suddenly dropped to around 40% charge after several days, with brand new batteries, and just stay there? The battery pack voltage is nominal, so I can't very well have had one of the new cells fail unexpectedly. -- Phil Stracchino, CDK#2 DoD#299792458 ICBM: 43.5607, -71.355 [email protected] [email protected] [email protected] Renaissance Man, Unix ronin, Perl hacker, Free Stater It's not the years, it's the mileage.
