600.0. "temperature access by VMS" by DECLNE::NICHOLSON () Tue May 13 1997 13:25

    How can I get the temperature of the system running VMS?
    Is the temperature reported by SRM accessable by VMS?
    Where is the temperature sensor?

600.1Temperature available in a future release.STAR::jacobi.zko.dec.com::jacobiPaul A. Jacobi - OpenVMS Systems GroupTue May 13 1997 14:208
Currently there is no way to obtain the temperature under OpenVMS.

In a future release, we plan to make the system temperature available 
to a remote PC running ServerWorks.

600.2re .1: how about local access too?BBPBV1::WALLACEjohn wallace @ bbp. +44 860 675093Tue May 13 1997 17:377
    I could read .1 as meaning "you can't get at it locally, you will
    need a PC".
    
    Can I safely assume that's NOT what you meant ?

600.3Local hack will be availableSTAR::jacobi.zko.dec.com::jacobiPaul A. Jacobi - OpenVMS Systems GroupWed May 14 1997 15:1516
The only documented and support way to obtain the temperature is via 
a remote PC with ServerWorks.  The OpenVMS system must be running UCX 
V4.1 TCP/IP networking, plus some additional software planned for a 
future release of OpenVMS.

I can supply a small test program which uses new undocumented 
$GETSYI item codes to obtain the information.  This test program will 
not be supported or documented.

Note the temperature sensor is located on the I2C bus, which requires 
a several thousand line device driver to support the bus protocal.
