iscsiadm login failed

[Saeed Mirzamohamadi]

Hi

I'm trying to connect my open-iscsi initiator to target, but failed to login with the command "sudo iscsiadm -m node --login". Here is my error:

Logging in to [iface: default, target: iqn.2003-01.org.linux-iscsi.ubuntu.i686:sn.1fe6a7cbc123, portal: 192.168.157.161,3260]

iscsiadm: Could not login to [iface: default, target: iqn.2003-01.org.linux-iscsi.ubuntu.i686:sn.1fe6a7cbc123, portal: 192.168.157.161,3260]: 

iscsiadm: initiator reported error (19 - encountered non-retryable iSCSI login failure)

iscsiadm: Could not login to [iface: default, target: iqn.2003-01.org.linux-iscsi.ubuntu.i686:sn.d0a998675819, portal: 192.168.157.160,3260]: 

iscsiadm: initiator reported error (8 - connection timed out)

I'm using instructions in the following link:

https://help.ubuntu.com/lts/serverguide/iscsi-initiator.html

iscsiadm discovery is OK too.

and my target is LIO. It's fine and my targetcli shows this:

o- / ..................................................................... [...]

  o- loopback ....................................................... [0 Target]

  o- tcm_fc ......................................................... [0 Target]

What might be the problem? I have searched a lot but didn't find anything beneficial.

Additionally I'm using both initiator and target in same computer.

My system: Linux ubuntu 12.04 LTS.

Thanks in advance!

I'm guessing that you've not setup CHAP authentication properly for the
initiator NodeACL listed below, or disabled authentication enforcement
via:

set attribute authentication=0

from within TPG context. You might want to have a look at:
