It did. the /etc/xen/scripts/block-iscsi script basically just
logged into the lun, found the /dev/mapper/ device and used
write_dev to pass it back up to xen. This worked fine in xen 3.2 but
now is giving me problems in xen 3.3.

Yes, manually setting 'phy:/dev/mapper/...' works great, but this
requires me to have some system setup to make sure every host has
every lun logged in all the time. I'm sure I'm going to hit some
iscsi connection limit this way.
