prtdiag on Netra 240 and 1125

"prtdiag -v" on our Netra 240 servers shows a great bunch of detail,
including environmental temps and fan speeds (which is what we want to
monitor). However, running "prtdiag -v" on our Netra 1125 servers does
not have nearly as much output, and does not include the temps and fan
speeds. Is there a different way that should be used to monitor temp
and fan speeds on the Netra 1125 servers? Perhaps I need to install
some other drivers or software on the 1125s to get the "prtdiag -v" to
provide the appropriate output?

Thanks,
Scott
