Please check the ACL in the target and verify that it includes the
initiator IB address
Run: tgtadm --lld iscsi --op show --mode target
If it is not you should add your initiator to the ACL using:
tgtadm --lld iscsi --mode target --op bind --tid=[id]
--initiator-address=[src-ip]

Also running iscsiadm -m discovery will create a node with tcp
transport and not iser.
If you want to use iser transport use iscsi_discovery script on the initiator.
