Pretty much any character based (raw) storage device is usable for iSCSI
export, this would include raw zvols
(/dev/zvol/rdsk/POOL_NAME/VOL_NAME), /dev/rXXXX and LVM
(/dev/VG_NAME/rLV_NAME).  I have used a couple of these personally with
NetBSD and MS-WINDOWS.

But as mentioned, unless you have a very specific reason, you will
probably want to make sure that the entire device is exported.  That is,
you could export /dev/rsd0e where 'e' is not the entire device, but you
may have more likely meant /dev/rsd0[c|d].
