No, but what you want to do is send a TEST UNIT READY to one of the target LUNs ... you can trigger that from the FC transport class, I think. That should return a CHECK CONDITION/UNIT ATTENTION which will trigger the collection of sense and the new uevent mechanism for doing a rescan. This hooks it into the standard AEN UNIT ATTENTION handling rather than having this all done per-transport. The only per-transport thing we need is to trigger collection of the UA on the transport specific AEN.
