I have a target running CentOS 7 with LIO. I am using iser transport via
Mellanox Connect-X 3 VPI cards. I have been having difficulties connecting
via an initiator running CentOS 7. My setup is essentially a one
target/LUN/PORT.

Added new util script to aid in CNA setup
Here is my flow:
iscsiadm -m iface -I iface0 --op=new
iscsiadm -m iface -I iface0 -o update -n iface.transport_name -v iser
iscsiadm -m discovery -t st -p 192.168.111.100:3261 -I iface0
Output is:
New interface iface0 added
192.168.111.100:3261,1
iqn.2003-01.org.linux-iscsi.localhost.x8664:sn.0fa6846566d9
iface0 updated.
iscsiadm: No records found
See below for debug output.
