About a week ago, an XServe G5 of mine started powering off more or less randomly (after 1 hour, chances were good it for it to occur). A problematic UPS has already been cut from the loop, and today I cleaned the machine inside out with pressurized air. So far it runs, for now at least, with a load >= 2.0, but I am keeping an eye on whether this is a thermal issue.
To that end, I wanted to obtain some statistics. Despite sensors-detect(8) loads lm87.ko for me, running sensors(1) shows no sensors. Oddly enough, I found a "kfand" process running that seems to stem from therm_pm72.ko, which brings me to the sysfs files. Is there a reason sensors(1) is not supported for Rackmac3,1? Certain sysfs files have a value with an unknown unit. "current" is likely in Ampere, temperature must be in Celsius (because there's no way the server room is 54°F=12°C cold). Is there a way to obtain the trip points for the hardware? $ cd /sys/devices/temperature; grep '' *; backside_fan_pwm:32 backside_temperature:54.000 cpu0_current:34.423 cpu0_exhaust_fan_rpm:5340 cpu0_intake_fan_rpm:5340 cpu0_temperature:72.889 cpu0_voltage:1.252 cpu1_current:34.179 cpu1_exhaust_fan_rpm:4584 cpu1_intake_fan_rpm:4584 cpu1_temperature:68.526 cpu1_voltage:1.259 dimms_temperature:53.000 grep: driver: Er en filkatalog modalias:platform:temperature grep: power: Er en filkatalog slots_fan_pwm:20 slots_temperature:38.500 grep: subsystem: Er en filkatalog uevent:DRIVER=temperature uevent:OF_NAME=fan uevent:OF_FULLNAME=/u3@0,f8000000/i2c@f8001000/fan@15e uevent:OF_TYPE=fcu uevent:OF_COMPATIBLE_0=fcu uevent:OF_COMPATIBLE_N=1 uevent:MODALIAS=of:NfanTfcuCfcu _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
