stopping a processor

hi,
Can any plz tell what is the command for stopping a processor? suppose a system is accessing 10 processors and we want to stop the 3rd & 6th processor then whats the command in Unix?

thank u

it depends on your OS/Unix version. send us your "uname -a" output....

(btw.: in Solaris it would be "psradm -f <processor id>")

regards pressy

Which UNIX?
