I get the names of all the different iSCSi projects out there mixed up, so forgive me if i am on the wrong list to mention about the targetcli freebranch by Andy Grover of RedHat. It is the one built into the kernel and the default for RHEL 7 and newer versions of Ubuntu. He calls it freebranch but Datera.io contributed it to the kernel?

Do you have root access on both target (server) and initiator (client)?

If you have root on the server side / target, targetcli is used to set the username and password. yum search targetcli. There is an attribute to set the password. If you forgot, info can tell you as well as

` cat /etc/targetcli/saveconfig.json | egrep -i '(CHAP|PASS)' `

targetcli

ls

cd /iscsi/iqn.YYYY-MM.us.domain.iscsiServer:ramdisk4gb/tpg1/acls/iqn.YYYY-MM.us.domain.iscsiClient:client

info

Would watch Andy Grovers targetcli videos on youtube.

You have "auth" enabled but not set up correctly.

There are two types of auth: discovery, and session. It looks like your session auth is not set up correctly. You need to know the auth username and password. It has to be set up on the target (targetcli) and the initiator (open-iscsi).

Please share how your systems is configured. Did you set up your targets?

Assuming you set up your targets, and they are on targetcli, can you share your configuration file?

Also, can you ensure you have no auth set up on your initiator?

For? For the initiator, or the target?

Then who set up your targets, and how are they set up?

Our storage SDK API, I will take a look at the target config and paste it.
