this is confusing to me. The pool was made on all EFI labeled drives....

Basically, i did this:

7 raw drives brand new, never formated.

using a OpenSolaris LiveCD i labeled all 7 EFI (format -e then fdisk creat a 
single 100% solaris partition, then label EFI)


After doing that, i added the 7 drives to a FreeBSD 8.0 machine, created a 
raidz2 zpool using the entire devices and copied everything from another zpool 
on the machine to this one

(freebsd complained about GPT corruption but i knew from tests i did in 
virtualbox that this method of backup would work so i ignored it)


After i had all the stuff i needed in this new zpool, i exported it

Then i imported it on the OpenSolaris machine and it took....maybe 10 minutes 
to import...it didn't seem like anything was going on but i knew from watching 
the lists that sometimes this is the case with solaris, and i just leet it be.  
then all the sudden, the drive lights lit up and it imported.

What was weird is some drives were raw drives and some weren't

What i'm trying to find out is why this happened?

I've since replaced every drive in the original raidz2 with different drives 
and my zpool looks like this now:
