Request for Comments:
The Target Identifier specified in SAM is an Upper Level Protocol entity.  There does not seem to be a well defined means to return the Target Identifier?  There is a point of view that Target Identifier is a different entity from the Port ID.   Especially for Multi-Port Targets.   Is there concensus on that point?
Is there a consensus view on the persistance of this Target ID in the face of Hot-Swap issues on both the HBA and Device level?  For instance, if a controller card within a Target Device is hot-swapped, and that card happens to have a SCSI Port (regardless of Lower Level Protocol: SPI or FC or ...).  Does the Target Device ID stay the same or change?
