title: iscsiadm "no portals found"
body: <p>I installed a iscsi targets on a Centos6 server and configure one target that can be found on one client machine (Ubuntu 1304 in network 192.168.95.x).  However, when I add one more target and try to connect from another machine (Centos5 in same subnet) but it show "no portals found".  Below is the printout of the settings:</p>

  <p>In the ubuntu machine, it only found one of the target in iscsi target server but in the iscsi target server both target can be shown by using tgt-admin command.  Is there anything I configured incorrect?</p>
  
  <p>Thanks a lot!</p>
