Setup STGT iSCSI target

These steps are for Debian Squeeze.

apt-get install tgt

For example, build version 1.0.8.

cd ./tgt-1.0.8/usr
make ISCSI=1
strip tgtd tgtadm tgtimg
cp -v tgtd tgtadm tgtimg /usr/sbin/

Load the module and have the daemon listen on default port 3260

tgtd

tgtadm --lld iscsi --op new --mode target --tid 1 \
    -T iqn.2010-08.com.example:san1.disk

Allow access from segment 192.168.0.0/24 :

tgtadm --lld iscsi --mode target --op bind --tid 1 -I 192.168.0.0/24

For example, add /dev/mapper/vg_san-lv1:

tgtadm --lld iscsi --op new --mode logicalunit --tid 1 --lun 1 -b /dev/mapper/vg_san-lv1

tgtadm --lld iscsi --op show --mode target

Output:

# tgtadm --lld iscsi --op show --mode target
Target 1: iqn.2010-08.com.example:san1.disk
