The error 24 login error makes sense now. Attempts to use the same IQN created when enabling open-iscsi: InitiatorName=iqn.2005-03.org.open-iscsi:b1281821f9da These tools dont modify files in the /dist/arch/etc/iscsi/

[rancher@ranchr012 ~]$ /sbin/iscsi
iscsi-iname      iscsi_discovery  iscsiadm         iscsid

As you can see the command did not modify the suspected dependent files

[rancher@ranchr012 ~]$ sudo iscsi-iname -p iqn.jargon.dev
iqn.jargon.dev:1c3aed14b4de
[rancher@ranchr012 ~]$ sudo ros service start open-iscsi && sudo system-docker exec open-iscsi cat /dist/arch/etc/iscsi/initiatorname.iscsi
