You export raw partition device; if you want to have many targets from
one physical disk, you split the disk in any way you can - fdisk,
gpt/dkctl or ZFS zvols and export the raw varieties of those.
Im my case I have a 250GB disk which used to be GPT and split in some
10-12 partitions, some of which - 3 or 4 - were iSCSI exported; the
rest were used by NVMM virtual machines. Lately I destroyed these and
created a zpool in their place, now I am using zvols for the same
purpose, e.g. my targets file is:
...
extent0 /dev/zvol/rdsk/pail/iscsia 0 30GB
extent1 /dev/zvol/rdsk/pail/nbsd 0 4GB
# target flags storage netmask
target0 rw extent0 0.0.0.0/0
target1 rw extent1 0.0.0.0/0
The rest of the volumes are for VMs:
...
zfs list -t volume
