So the current model requires the complete removal of the device and a rescan on the host. Doing that from within the SCSI stack will open quite some interesting race conditions, let alone interesting userspace interactions. Alternatively we can change the model to allow for a change of the inquiry data, but that should be discussed.
And then there is the Power-On/Reset handling, which probably would warrant a discussion on its own ...
