Hello:

I have a server with 2 HBAs, and the users keeps complaining about performance problems. My question is, how can I relate the process with high I/O wait? Also, is it possible to see how much data is being pushed thru by my 2 HBAs?

iostat (part of the sysstat package) will answer your 2nd question.

I dunno how to measure io wait time per process. maybe IBM's NMON can do that, not sure, I haven't used it for a while.
