Yeah, I got bit by this one too, and scratched my head for *days* till I
figured out that chpt won't change the size of the partition for the device
that it is running against.  The secret is to do chpt -pa ... /dev/rrz2c
separately from chpt -pb ... /dev/rrz2a.

By the way, if your genvmunix will talk to your 3rd party disk, you can
use it as the boot device, even during initial installation, provided
you use the system maintenance mode or other means to get the partition table
established first, and Ctrl-C out of the advanced installation prior to
the /usr filesystem allocation to fake a disktab entry.  Reboot, and voila!
