I think Geoff and I were talking about using a tool like from sg3_utils, 
which sends scsi commands to the target. The scsi commands can change 
settings or do things like fail over a lun/controller. You are right 
though. The iscsi stuff has nothing to do with it. The scsi commands are 
just sent over iscsi. And it would be strange not to have a user 
friendly interface on the target, but allow you to do it with sg utils.
