Any chance intiation happens from inside initrd image? I haven't
worked with Centos or RedHat
in a while, but look at mkinitrd command to recreate an initrd image?

Are you sure it does not timeout? The default timeout is long, but it
should timeout eventually. Did you change it?

What is the errors in the log?

Did you chkconfig iscsid and iscsi services?

If you do not have any files in there then there is nothing for iscsi to
login to.

I think Misha might be right. What is in

/proc/cmdline

?

Hi, 

Thanks for your help, resolved the issue now.   It had been setup to load the kernel modules and mount the target via the initrd image.  

I can't tell you how frustrating that was to diagnose :)

I removed the offending lines, rebuilt the image, then fixed the issue.
