Re: iostat
You can give the disks you want to watch after the iostat command.
e.g.
iostat rz0 rz1 rz2 rz3 rz4 rz5 rz6 rz7 rz8 rz9 5 10
This will show you the statistics of the disks rz0 to rz9 after every five seconds and 10 such readings will be displayed.
Similarly you can use the command as per your requirement

Re: iostat
Also check out the improved "uaio" tool from,
ftp://ftp.alaska.edu/pub/sois/Overview.html#uaio
or: http://www.arsc.edu/~kcarlson/software/man/uaio.html
or better yet, if you have collect installed, use collect.
collect -sd -i5 (disk statistics at 5 sec interval)
regds,
Abdul.
