No. I don't know what exactly to setup, which is why I'm looking for a howto :)
Rudi, How exactly did you expect the daemon to know what you wanted to export without telling it, was starting the daemon w/o any config not supposed to yield any errors:)
For RHELs target: http://kbase.redhat.com/faq/docs/DOC-15154
Maybe what you missed from your own tutorial you posted at http://www.cyberciti.biz/tips/howto-setup-linux-iscsi-target-sanwith-tgt.htm... was the fact that the config wasn't persistent when entering commands at the console. If you restarted the service, it would come up unconfigured.
