Thank you Mike! I really appreciate your help.
nhnfs01 ~ # iscsiadm -m discovery -t sendtargets -p localhost
[::1]:3260,1 iqn.2012-10.com.nahoku:nhnfs00.target01
Process:
------------
#Install Centos 6.3 (64bit)
yum install scsi-target-utils iscsi-initiator-utils
mkdir /home/iscsi
time dd if=/dev/zero of=/home/iscsi/lun_exchange.img bs=1G count=300 &
time dd if=/dev/zero of=/home/iscsi/lun_mssql.img bs=1G count=300 &
#edit /etc/tgt/targets.conf
for svc in iscsi iscsid tgtd; do /etc/init.d/$svc restart; done
I created a quick test configuration to see if it would work, and
presto, it worked fine. When I changed the config, I still only have
a single Target. Is it possible to have two target servers when using
dd images?
Original test config: (worked great)
--------------------------
# Default Driver
default-driver iscsi
# Initiator and Target Configuration
<target iqn.2012-10.com.nahoku:nhnfs00.target01>
backing-store /home/iscsi/lun_mssql.img
</target>
Changed config: (initiators still see the target listed above)
----------------------
nhnfs01 ~ # cat /etc/tgt/targets.conf
# Driver
default-driver iscsi
# Targets
<target iqn.1997-03.com.example:nhnfs00-exchange>
<backing-store /home/iscsi/lun_exchange.img>
allow-in-use yes
</backing-store>
</target>
<target iqn.1997-03.com.example:nhnfs00-mssql>
<backing-store /home/iscsi/lun_mssql.img>
allow-in-use yes
</backing-store>
</target>
I have removed the services, deleted everything related in /etc and
/var/lib, reinstalled, and recreated the files from scratch. The old
information still comes up. There must be a binary database somewhere
referencing the "target".
