iostat for specific domain in sol9




hello everybody,
in my sol9 machine, im trying to see the io load occuring on the system, and i need to check the performance for some specific partiotions, i serched if there is any otpion for the iostat command so it can check the io load for some partiotn and not the whole system, i didnt found anything regading that.

do you have any idea how i can do that, whether using iostat or any other command.

like in tru64, i can use the following:
iostat " device name"
so it gives me the io state on that partition, do you have idea if there is any equivelance in solaris9.
