    Thanks to David Lodge, Jack Gallagher, Mark Summers and Bill Hassell.

    It does not appear that there is a software way to record the system temperature. The GSP console command just says the temperature is NORMAL and does not let you know if the temperature is rising.

    The Master, Bill Hassell, gave the best answer:

      "Not true at all. Older systems have *no* thermal protection and will
      meltdown before crashing. N,L,A class have thermal sensors that go
      off (generate a diagnostic messages) for early warning, disaster and
      will perform a shutdown above 100 deg F apx. NOTE: This is approximate
      and the processor will do nothing about tape drives and disks and
      printers that are melting in the same room.

      I find it ironic that thousands to millions of dollars of computer
      equipment is at risk every day because air conditioning is never on
      the critical list for redundancy and notification. Several people
      have asked me for a way to email a warning...but what if the email
      server is already overtemp or the network router is already dead?
      A simple chart recorder is much more useful than a rough-guess sensor
      in a general purpose computer.

      With so much at risk, I would get a proper tool to monitor and create
      non-ignorable warnings when temperatures are out of control. In most
      computer rooms, 100% loss of air conditioning means destructive temps
      in less than 5-10 minutes. I would always have an overtemp circuit
      breaker that pulls the plug on the entire room when temps go about
      90-100 deg F."

    I thought I read somewhere that it was possible to obtain a realtime ambient system temperature from a 9000 server.
    Is this true or not? I know Sun systems can as we are already doing that so I would think that HP's can as well. The only info in the ITRC I have found is about a system overtemp being recorded in the diag_log and a patch that is supposed to generate a warning first before shutting down the system.

    If it is possible, can anyone direct me to any documentation on how, or tell me how.

    Thanks
