Hey folks,
I'm running RHEL 5.3 on 6 boxes - and on every one of them sensors-detect finds nothing.
5 of them are Sun fire 2250 machines, and 1 is Sunfire 4170.
Googling and searching this list does not seem to find anything.
When I log into the Sun hardware management interface (web interface) I see that it of course is correctly detecting various temperatures of things. But for some reason Linux is not.
Does anyone here have experience in this area and can tell me how to fix this?
thanks, -Alan

Definitely running an out of date OS won't help. Updating the kernel to current fixed a similar problem I'd had with no usable sensors being detected.

Yeah, I'd really like to do that - but I've only been here a week now and don't understand these systems well enough yet to know whether or not that will break anything.
Though I can probably upgrade 1 of them and let it soak for a few weeks to see what happens.

Yep. Do one (upgrading kernel and lm_sensors to current), and you might find it still can't see any sensors anyway...

you may need to use ipmitools rather than lm_sensors.

What did Red Hat say?

First try updating to the latest release to get the latest kernel / lm_sensors packages.
Red Hat did a major overhaul of the hwmon branch in the RHEL-5.5 release, backporting many updated drivers from the upstream kernel ~2.6.26 (dating from somewhere around Aug 2008), but obviously even this updated driver branch is now over 3 years old.
What hardware sensors do your servers have? Elrepo.org has some updated kernel drivers for commonly used hardware sensors backported from newer upstream kernels (e.g, 2.6.39, 3.x), but some are reliant on the latest distro kernel (built against a later distro kernel) due to kernel ABI changes, so you'd still need to ideally be running an updated installation.
