Definitely could be some strange corner case interpretation in the IPMI spec I missed. > > 1104 | System Fan 2 | Fan | 14106.36 | RPM > | N/A | N/A | N/A | 3996.80 | 3475.48 | N/A > | 'OK' > > Here's the problem: the fans are reported as being above threshold when > running at 14K RPM which is their nominal normal speed; it seems to me > like the Upper NC and Upper C should be instead Lower NC and Lower C > respectively — it feels extremely strange that the Upper NC is higher > than the Upper C. Yeah, you would think it's be amongst the "lower" thresholds than the "upper" ones. > This happens on the DL140 G3 firmware 2.21, but it's similar to what > happens on a DL160 G6 firmware 4.20: > > 3440 | FAN1_OUTLET | Fan | 12621.48 | RPM | > N/A | 0.00 | N/A | N/A | 999.20 | N/A > | 'OK' > > In this case the Lower C is correct, but the Upper C is wrong (and > should probably be Lower NC). > > 2128 | FAN_3 | Fan | 2049.64 | RPM > | N/A | 0.00 | N/A | N/A | 978.81 | N/A > | 'OK' > > And on the ML160 G6 firmware 4.23 (which is the only one I could update > at this point) there's the same issue (in this case it's not a rackmount > so the fans are slower). > > Albert do you think there might be something to be done to fix this by > chance? Could you send me the --debug output for one of these sensors. I'm wondering if HP put the thresholds into the wrong fields in the SDR. That would definitely mess things up. I assume the output was good/normal before the firmware update?
