How can I tell what is using disk ?

How can I tell what is using a specific disk ?
If I do a iostat command, I see that Hdisk2 is 96% busy.
How can I tell exactly what it is doing ?

Hi,

clear in you mind, what is there on your disks:

Using commands

#lsvg
#lsvg -l xxxxvg

or together

#lsvg | lsvg -i -l

and

#lsdev -Cc disk
#lspv
#lspv -l hdisk??

#lsps -a ( for paging)

Done this, if you have 433, use topas:

In just one monitor you see together
iostat, vmstat, and ps : when you see a pick in disk
you can see which process is at the top of cpu

Bye
