I am currently using opensolaris snv_134 have just bought some 3 TB disks to
upgrade a 8 disk mirror of 2 TB disks. I though this should just work as
opensolaris can use EFI partiton tables, but giving zfs the whole
unformatted disk results in the following partition table and pool size.

/dev/dsk/c6t48d0s0 is part of active ZFS pool test. Please see zpool(1M).

test being the single 3 TB disk pool.

My google skills seem week on this problem, as I seem to be only able to
find stuff about 4kb sectors and not being able to boot > 2TB yet.

Can I use 3TB disks, if so how?
