Pulling iostats info from ESS vpath devices 1

[Blizard]

I am trying to gather performance stats on vpath devices (virtual devices presented by System Device Driver 'SDD' from SAN-attached ESS storage), and I am having difficulty on my v5.1 machines. AIX v5.2 added a new switch '-m' to the iostat command that works great, but it doesn't exist in v5.1. I have played with the 'datapath query devstats' command from the sdd command set, but it doesn't give me much to work with.

Does anyone know a way to find/derive these stats? Maybe I just have to wait until I upgrade all my machines to 5.2 or higher...
