This is slightly an aside but mpxio should let you add paths on the fly.
You could ....
* Deport the pool
* Enable mpxio (Most people use stmsboot)
* Reboot
* Import the pool
* Start your test
* Monitor with a varient of iostat including the "-X" flag
* Plugin the new cable or path
* "cfgadm -c configure" the new controller
* See if the i/o goes up and the new path is used
