 <code> <code>
 # cat /etc/iscsi/initiatorname.iscsi  # cat /etc/iscsi/initiatorname.iscsi 
 </code> </code>
  
-Then on the server+Mine looks like this: 
 +<code> 
 +InitiatorName=iqn.2005-03.org.open-iscsi:91871cf5e261 
 +</code> 
 + 
 +It will be important later. 
 + 
 +Next we need to configure our target (that'the 'server' remember?).  In order to do this we use something called target-cli, so get targetcli-fb from Slackbuilds and install it: 
 + 
 +<code> 
 +slpkg -s sbo targetcli-fb 
 +</code> 
 + 
 +Targetcli requires a directory to store its data, make sure it exists:
  
 <code> <code>
 # mkdir /etc/target # mkdir /etc/target
 </code> </code>
 +
 +targetcli is a bit like a command-line directory browser except you use it to change values in a hierarchical store. That same hierarchy also contains the commands you invoke to make changes, however.  You've probably not seen anything like it before and it's best just described by example.
 +
 +Start by launching targetcli
 +
 +<code>
 +# targetcli
 +targetcli shell version 2.1.51
 +Copyright 2011-2013 by Datera, Inc and others.
 +For help on commands, type 'help'.
 +
 +/>
 +</code>
 +
 +Assuming you have a spare (unused) disk, you can now create a block device, e.g.:
 +
 +<code>
 +/> backstores/block create name=myblockdevice dev=/dev/sdb
 +Created block storage object block using /dev/sdb.
 +</code>
 +
 +Next move to the iscsi target creation step.  Just type create and allow the target to be given a generated name, it's good enough for our purposes.  You can give your own name if you want but I saw little point for my setup.
 +
 +<code>
 +/> iscsi/
 +/iscsi> create
 +created target iqn.2003-01.org.linux-iscsi.iscsi-server.x8664:sn.7f83425fbbe8
 +Created TPG 1.
 +Global pref auto_add_default_portal=true
 +Created default portal listening on all IPs (0.0.0.0), port 3260
 +</code>
 +
 +Next create LUN for the created target. Type the name of the target/tpg1 to move to the configuration area:
 +
 +<code>
 +/iscsi> iqn.2003-01.org.linux-iscsi.iscsi-server.x8664:sn.7f83425fbbe8/tpg1
 +</code>
 +
 +Then configure it:
 +
 +<code>
 +/iscsi/iqn.20....425fbbe8/tpg1> luns/ create /backstores/block/myblockdevice
 +</code>
 +
 +Then add an ACL by moving into the acl area and creating an ACL which matches the name of the initiator name that you got from the client:
 +
 +<code>
 +/iscsi/iqn.20....425fbbe8/tpg1> acls/
 +/iscsi/iqn.20....be8/tpg1/acls> create iqn.2005-03.org.open-iscsi:91871cf5e261
 +</code>
 +
 +Simply exit to save your changes:
 +
 +<code>
 +/> exit
 +Global pref auto_save_on_exit=true
 +Last 10 configs saved in /etc/target/backup.
 +Configuration saved to /etc/target/saveconfig.json
 +#
 +</code>
