# create a disk image root@dlp:~# mkdir /var/lib/iscsi_disks root@dlp:~# dd if=/dev/zero of=/var/lib/iscsi_disks/disk01.img count=0 bs=1 seek=10G
root@dlp:~#
vi /etc/tgt/conf.d/target01.conf # create new # naming rule : [ iqn.yaer-month.domain:any name ]
<target iqn.2017-06.world.srv:target01>
# provided devicce as a iSCSI target
backing-store /var/lib/iscsi_disks/disk01.img
# iSCSI Initiator's IP address you allow to connect
initiator-address 10.0.0.31
# authentication info ( set anyone you like for "username", "password" )
incominguser username password
</target>
root@dlp:~#
systemctl restart tgt
# show status root@dlp:~# tgtadm --mode target --op show
