It took me some time to come back full circle to this. I've worked quite a bit on this with little success so far. It seems like it's been done but on some of the forums and Github, there are no responses yet. This is essentially a cross post from a seemingly dead list. Hopefully someone here will have some suggestions.
I've googled this particular issue and not really finding any good results on how to resolve it.
I installed targetcli via yum on CentOS 7 and this is the version in the repo: # targetcli targetcli shell version 2.1.fb49 Copyright 2011-2013 by Datera, Inc and others. For help on commands, type 'help'.
I downloaded the .zip of the targetcli-fb version and tried it too from the scripts folder and same results.
Python: # python --version Python 2.7.5
Libs: Installed Packages python-configshell.noarch 1:1.1.fb25-1.el7 @base python-rtslib.noarch 2.1.fb69-3.el7 @base python-rtslib-doc.noarch 2.1.fb69-3.el7 @base
The error comes up when using create. /> /qla2xxx create naa.xxxxxxxxxxxxxxx Could not create Target in configFS
Below is the info on my FC /> qla2xxx/ info Fabric module name: qla2xxx ConfigFS path: /sys/kernel/config/target/qla2xxx Allowed WWN types: naa Allowed WWNs list: naa.xxxxxxxxxxxxxxx, naa.xxxxxxxxxxxxxxx, naa.xxxxxxxxxxxxxxx, naa.xxxxxxxxxxxxxxx, naa.xxxxxxxxxxxxxxx, naa.xxxxxxxxxxxxxxx, naa.xxxxxxxxxxxxxxx, naa.xxxxxxxxxxxxxxx Fabric module features: acls Corresponding kernel module: tcm_qla2xxx
I have attached the log but don't see anything that really stands out. log.txt
I checked per the link http://www.linux-iscsi.org/wiki/Fibre_Channel#Enable_target_mode to ensure that I have initiator mode disabled

Should I be able to create a directory in /sys/kernel/config/target/qla2xxxx? # mkdir naa.10008c7cffc7ef01 mkdir: cannot create directory ‘naa.xxxxxxxxxxxxxxx’: Invalid argument
I did notice that when I rebooted, there was no qla2xxx folder in /sys/kernel/config/target/ but after trying to use targetcli, it did make one so I'm not sure what else would cause it to fail.
Suggestions?

For quite some time I’ve been using FreeNAS to provide services as a NAS over ethernet and SAN over Fibre Channel to CentOS 7 servers each using their own export, not sharing the same one.
It’s time for me to replace my hardware and I have a new R720XD that I’d like to use in the same capacity but configure CentOS 7 as a Fibre Channel target rather than use FreeNAS any further.
I’m doing virtualization and this will allow me to have failover from one node to the other since they’ll all be sharing the same export rather than me simply backing up to the FreeNAS server the way I am now.
Does anyone know of any really good current articles that explain how to set up CentOS 7 as the target in such a configuration and also setting up CLVMd so they can all share an export over Fibre Channel from CentOS 7?
