Is there any way to show actual disk IO operations per second. sysstat shows cifs and nfs ops, but we're wondering how that translates into actual IOps underneath the hood (or is it all hidden away)?
thanks

In recent OnTap, you have the stats command, which an interface to the Counter Manager (cm).
you can get pretty much anything you want, and customize stats using "stats presets" config files.

do a 'priv set advanced' then 'statit -b' to start collecting statistics. statit -e will stop collecting and print many low level stats about each disk activity including % utilization. This is very usefull to diagnose a disk i/o bottleneck.
