On Solaris, how can I tell what processes are doing disk i/o on a particular device?

Question

On Solaris, iostat tells me that a device is 92% busy, but how do I find out what programs are making the requests?

If you mean Solaris 10 try iotop, a DTrace script by Brendan Gregg. It lists the device (fifth column).

You can find some other particularly useful DTrace scripts at http://prefetch.net/articles/solaris.dtracetopten.html.

iotop is also part of the [DTrace Toolkit](http://hub.opensolaris.org/bin/view/Community+Group+dtrace/dtracetoolkit) – user9517 May 04 '11 at 15:32
I tried it, but alas my login is insufficiently privileged. – Thomas L Holaday May 04 '11 at 18:14
