I think I might be able to solve my issues if I could filter out which of t= hese entries returned by=20 ipmitool sdr type "Power Supply" actually represent the physical power supplies. One of the cases I have bel= ow for example produces a list of six sensors. Only two of those actually r= epresent the true physical status, but when I'm writing generic code, how d= o I filter these? In some cases the ones I want are called "PS 1 STATUS" an= d "PS 2 STATUS" and in others "PS1 STATUS" and "PS2 STATUS" are used (note = the missing space). Yet another one just uses "Status" for both PS sensors.= This is all very non-deterministic. Is there a call I can make in the ipmi= tool library to list only the sensors representing the real power status an= d not these other sensors like "PDB PRESENT"? -----Original Message----- From: owner-freebsd-questions@freebsd.org [mailto:owner-freebsd-questions@f= reebsd.org] On Behalf Of Peter Steele Sent: Tuesday, March 30, 2010 8:42 AM To: freebsd-questions@freebsd.org Subject: Making sense out of impitool power supply readings Is there some trick to know when the power supply sensor readings returned = by ipmitool actually reflects that there is a power supply issue? Our diffi= culty is that no one seems to use the same sensor values when it comes to p= ower supply reporting, and even if there are two power supplies the impitoo= l command may only report a single status. For example, here's one box that= I have: # ipmitool sdr type "Power Supply" PS 1 STATUS | 61h | lcr | 10.0 | 0 unspecified PS 2 STATUS | 62h | lnc | 10.1 | 0 unspecified PS REDUNDANCY | 6Fh | lcr | 19.0 | 0 unspecified Here's another: # ipmitool sdr type "Power Supply" Power Supply | 17h | ok | 10.0 | 0 unspecified And another: # ipmitool sdr type "Power Supply" PS1 PRESENT | 53h | ok | 10.0 | Device Present PS2 PRESENT | 54h | ok | 10.1 | Device Present PDB PRESENT | 55h | ok | 21.0 | Device Present PS1 STATUS | 4Ah | ok | 10.0 | PS2 STATUS | 4Bh | ok | 10.1 | PS REDUNDANCY | 4Dh | ok | 21.0 | Fully Redundant And here's yet another: # ipmitool sdr type "Power Supply" Status | 64h | ok | 10.1 | Presence detected Status | 65h | ok | 10.2 | Presence detected PS Redundancy | 74h | ok | 7.1 | Fully Redundant All of these are systems with dual power supplies. When we query these sens= ors are queried, on some systems "0" means the power supply is online and "= 200" means it's offline, whereas others might user 80 and 180 or 180 and 38= 0. Is there some trick in figuring out what status values means "online", o= r would we have to maintain a table of motherboard/vendor versions and map = these to how to interpret the PS readings? _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman= /listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org= "
