Did you tried partitioning with gpart and then UFS2 + SoftUpdates on 
/dev/da0p1?
I am using it with 7.2-STABLE from January and iscsi_initiator 2.2.4 on 
Dell MD3000i (2.7TB partition)

gpart create -s GPT da0
gpart add -b 34 -s 205520830 -t freebsd-ufs -l MyLabel da0
newfs -U /dev/da0p1

Just substitute 205520830 with size of your storage.
