We have a couple of E420r and need to find a way to check the
temperature on them. On other Sun server the prtdiag command display
the temp., but not so on the E420r. Is there some esoteric command
which I am not aware of ?

Did you check google?

searched for: temperature e420r

found:

http://sunportal.sunmanagers.org/pip...ly/001955.html

which seems to suggest that it just can't be done since there's no
hardware on an E420r to sense the temperature and make that information
available to the system.

I think that is the server version of the Ultra 80 workstation, in
which case, as someone has said, it can't be done. There is however an
overtemperature sensor which will shut the system down (I assume just
removes power) if it gets too hot.

However, you might find checking the disk tempterature a usable
alternative. That can be done with all modern SCSI disks, which have a
temperature sensor in them. There is the smartmontools package that
someone has developed for this, or the following like shows a very
short C program that can read the temperature of a disk.
