iscsiadm command shows error 'No records found'

Issue

• We have exported 40 gb partiton (/dev/cciss/c0d0p10) through iSCSI protocol. The command tgt-admin -s is showing LUN details on target but we are not able to scan it, the iscsiadm command shows following error on initiator:

  $ tgt-admin -s
  Target 1: iqn.2015-01.new.target:disk1
      System information:
          Driver: iscsi
          State: ready
  [...]
  
  $ iscsiadm -m node -T iqn.2015-01.new.target:disk1 -p 192.168.0.19:3260 -l
  iscsiadm: No records found
  
  $ iscsiadm -m session
  No active sessions.
  

The iscsiadm command shows different target IQN from the one reported by tgt-admin -s command on iSCSI target:

    $ iscsiadm -m discovery -t sendtargets -p 192.168.0.19:3260
    192.168.0.19:3260, iqn.2015-01.old.target:disk1
