SUMMARY: Looking to Disable CPU's

99% of the replys said to use psradm, and that is what I did.  "man psradm"

I put it in inittab so that it would take affect no matter what runlevel I
was in and would
not depend on scripts.

A couple people gave a way to disable it in hardware:
You need to take the E450 down to the OBP prompt, then issue the following
commands:-

OK>.asr         <-- This will tell give a  status of configurable
components. (Remember
           the fullstop)
OK>asr-disable CPU1
OK>asr-disable CPU2
OK>asr-disable CPU3
OK>.asr

You should now see three of four CPUs disabled. This will last across
multiple
power cycles and can be reversed by using the asr-enable command. They are
not
visible to the OS after you disable them. You might want to disable
different
CPUs as CPU4 is usually the first one installed.

Another person had a good idea: using psrset, create a processor set of one
CPU and bind my process to that.
That way you are meeting licenseing requirements, and are still using the
other CPU's for other work.


Thanks to everyone
