Zone Configuration Doubt

UNIX Solaris
1

Hi All,

I Have Sun SPARC T5220 is a single processor machine with 8 cores.
I want to create a zone which should take 3 cores.
So how can I Configure those 3 cores to zone?
and
Once I configured some particular cores to zone and if I want to increase or decrease the cores how can I do it?

Please explain me a little bit broadly......
I am new to this solaris.........

Thx for the reply

One more Doubt
If I want to change the value of ncpus to some other value then how can we edit it?
Is there any possibility to remove dedicated-cpu, which should not effect my current configuration?
