top utility iowait column

[Guest_imported]

I was wondering if there is any utility out there that can correlate the percentage of iowait to a particular process.

The percentage of iowait I'm referring to is the column found when you run the top utility.

I don't know about tying the I/O wait to a process, but usually a lot of I/O wait means writing to a tape drive or another system. Backup to tape still running etc.
You can look in top for processes like cpio, ufsdump.
