From: Mike Christie <michaelc@xxxxxxxxxxx>
targets.onf/tgt-admin does not support the readonly feature.
To set this with tgtadm you can run:
tgtadm --lld iscsi --mode logicalunit --op update --tid 1 --lun 1 \
--params readonly=1
This patch attempts to add it so you can set it in targets.conf by
doing:
<target iqn.2008-09.com.target>
readonly 1
backing-store /storage/lun1
</target>
