Normally the bootimage itself should take over the mounting. You should not 
bother with it. I don't know if you can easily remout a gfs with changing the 
lockproto. So as you don't get any errors and it didn't do anything it does 
not work.

But again, normally the initrd mounts the gfs filesystem you specified within 
you cluster.conf. We didn't test with raw-devices we are always using 
LVM/CLVM lvs for doing the mount.

So when the initrd gets the iscsi disk as scsi-disk all the rest should be 
done automatically.

To test it switch on com-step and break where scsi is detected. Setup you 
iscsi stuff and exit and let the initrd init process do the rest.
That should work.
