Its been awhile, but it seems like in the past, you would power the system down, boot from removable media, import your pool then destroy or archive the /etc/zfs/zpool.cache, and possibly your /etc/path_to_inst file, power down again and re-arrange your hardware, then come up one final time with a reconfigure boot. Or something like that.
I remember a similar video that was up on YouTube as done by some of the Sun guys employed in Germany. They build a big array from USB drives, then exported the pool. Once the system was down, they re-arranged all the drives in random order and ZFS was able to figure out how to put the raid all back together. I need to go find that video.
