Hello,
I have a 6500 with 10 cpu boards and 20 cpu's running.
Due to an Oracle licensing problem, I need to turn off 4 CPU's
using the "psradm -f x x x x" commands

Can I run this command on a fly, ie turn off cpu 0,1,2,3 online?
what happen when a system process is running on cpu 0, and I tried to
turn off cpu 0?

Will it crash the server, or is the server smart enough to move the process
to another on line cpu's?
Also, do I have to reboot the server after I turn off using "psradm"?
Thanks,
