Hi Tom, There are some facilities in Solaris for reading platform sensors, but what you can do varies quite a bit from platform to platform. On our sparc/sun4v platforms I believe you can get access to sensor readings and discrete states using the prtpicl(1m) cli. This functionality had been around on sparc since I think Solaris 8.
In build 96 of Solaris Nevada, we added the ability the enumerate and read sensors on our X64 servers and our Sun Storage J4000 series platforms. You can find some more information on this in my blog entry here: http://blogs.sun.com/robj/entry/a_sensor_abstraction_layer_for And also in Eric Schrock's blog entry here: http://blogs.sun.com/eschrock/entry/ses_sensors The framework we developed is not directly probing/reading the sensors, but rather proxying the requests to the service processor or storage enclosure using IPMI and SES. As a result, it doesn't support boxes that don't have bmc's (i.e. desktops/laptops) The Solaris source has an smbus and i2c nexus driver and an assortment of i2c slave device drivers, but it is currently compiled for sparc only. It might be an interesting project to move that to common code and update it with newer i2c slave device drivers. I don't know if anyone is looking in that currently.
