I whish the maintainer of iostat would add a friendly name option, it 
would not be so hard to code a device-mapper -> LVM translation using 
"dmsetup ls" , problem is you can only run that command as root. ( guess 
you could add a sudo rule... )

anyways, if you don't find the time to work on this, just just provide a 
sample output of solaris's /usr/bin/iostat -xrn and I'll post the 
changes needed to the list.

Thank !


Dan
