Hello,

Nothing like a 4 year old post to help me out here...

I am currently experiencing a performance issue on my 3PAR 8400. We are leveraging AO. I am getting anywhere between 20 to sometimes 100 disk reporting High I/O. The disk are FC as well as NL storage. What command is best used to determine what volumes are currently causing the High I/O?

Thanks Paul!
