A quick howto on making your ClearOS 5.2 Install host ISCSI shares for other devices to mount up and use.

nano /etc/suvad.conf
# Edit this line and change the port from 3260 to something else:
ifn="lo" port="3260" dst-host="rsb.clearsdn.com" dst-port="1875"/>
# Should not effect suvad backup service as there are two ports but did post in the forums on CC to confirm.
service suvad restart

# ED: Install the various bits and pieces you need here
yum install scsi-target-utils

# Now I am going to create a test iscsi target LUN
# I am using a simple Disk Based File here but you can point this at actual partitions - various google searches have all the info you could need on how to do this:

service tgtd start
tgtadm --lld iscsi --op new --mode target --tid 1 -T iqn.2010-12.com:storage.jim.test
tgtadm --lld iscsi --op new --mode logicalunit --tid 1 --lun 1 -b /dev/sdb1
tgtadm --lld iscsi --op new --mode logicalunit --tid 1 --lun 1 -b /fs.iscsi.disk
tgtadm --lld iscsi --op show --mode target
tgtadm --lld iscsi --op bind --mode target --tid 1 -I ALL
# To make sure the above survives a restart
tgt-admin --dump > /etc/tgt/targets.conf
chkconfig tgtd on

# Here are a command that is probably worth noting as it becomes very useful off the bat:
tgtadm --lld iscsi --op new --mode logicalunit --tid 1 --lun 1 --backing-store /backups/storage.jim.test.backup.img

# And if you need to confirm that everything is working the way you wrote/planned:

[root@portal tgt]# tgtadm --lld iscsi --op show --mode target
Target 1: iqn.2010-12.com:storage.jim.test
