Ive posted previously on this topic, and tried multiple times but cannot get around a problem trying to configure ISCSI targets. Specifically, I have tried 2 different physical machines as well as a VM, all running Cent OS 6.5.
Guides on the network suggest it's fairly simple to setup, but for some reason, I encounter the same configuration error during daemon start-up and have not been able to work around it at all.

I was hoping there might be a "better" guide somewhere, perhaps more comprehensive or with greater detail, because the 2 guides I followed both resulted in the same error, so it's not "random", there is definitely something missing or not setup correctly.

Other than finding a more comprehensive guide, does anyone know of a pre-built VM which can be used to manage iSCSI Target luns?

You are trying to set up a server to HOST LUN TARGETS? Or you are setting up a server to CONNECT TO LUN TARGETS?

Either one is fairly simple, just let me know which you are doing.

Im trying to create scsi target luns for export as block devices to other CentOS nodes.

The short and sweet is:

Install iscsi-initiator-utils.x86_64

Configure tgtd

Discover LUNs on client computer

Create LVM on LUNs from client computer

I think this is one of the more complete tutorials: http://opentodo.net/2012/10/setup-is...r-on-centos-6/

Run through it and report back as to where you are getting hung up. I can spin up my old iSCSI target machine from my RHCE days, or set it up again to help you through it. If you tell me where it's breaking down, we can focus on it and get you past it.
