Hi
I have output from iostat that I can't quite work out.   I'd be grateful for any insights that others may be able to provide.

Our environment is a T4-2, running multiple LDom's.   One LDom is reporting heavy "disk" utilisation ( the disk being a SAN LUN ).  The Ldon is running Oracle's 12C Grid Control product  on Solaris 11.1.   There are two LUN's - one for the O/S, one for the Oracle software.   16Gb and one core allocated.

We've noticed the Oracle LUN being busy, as show below :-

Howdy, Stranger!
