Interestingly, I was doing just that, when your e-mail arrived...
ipmitool was impressive enough and I'm building openipmi to take a look
at that too.
I don't see information on each DIMM (yet?), but other information is
One of the fans, for example, was listed as "cr" (rather than "ok") --
which was, apparently, causing all other fans to run at maximum speed
(*very* noisy fans in poweredge 2900).
I reset it (by pulling it out and back again), and now the box is
quieting back down...
The sensors-patches did not add any new entries under hw.sensors
The coretemp(4) stopped functioning, unfortunately... Whereas before,
when I simply kldload-ed it, it was reporting reasonable temperatures,
now that I have the sensors-patch merged in, I see nonsense like:
hw.sensors.cpu0.temp0: -1282,97 degC
hw.sensors.cpu1.temp0: -1272,97 degC
hw.sensors.cpu2.temp0: -1282,97 degC
hw.sensors.cpu3.temp0: -1262,97 degC
Seems like some kind of calibration issue -- the numbers differ from
each other and change with time... I think, I'll back the patch out as
it did not give me any new information -- the it- and lm-devices aren't
found on this box :-(
Anyway, sdtemp(4) -- or equivalent -- is something, I'd like to have...
