Solaris

First of all I'm new to solaris. Today is the first day i'm practicing zones.

In global zone i have created a two separate pools of 2CPU's and created a email-zone and a web-zone as given in a PDF. I deleted the 2 zones in the processor sets. How can i destroy the processor set and i want my system to be exactly like how it was before i installed zones.
When i type in
command # poolcfg -c info (it displays like below)



I want to delete "pset email-pset" and "pset web1-pset"

Please help. Thnxs in advance

See "man psrset".

Thanks for replying. i tried man psrset.

But still i was not able to delete it.

psrset -d 1 and psrset -r 1 ..... It says
could not remove processor set 1: Operation not supported

psrset -q 1: to look for any dependecies,it says
process id 1: no bound

I tried with -f and -F

Thanks
