In of SAM-5r18 there is the following sentence.
The relative port identifier for a SCSI port shall not change once 
assigned unless physical reconfiguration of the SCSI target device occurs.
What is the definition of "physical reconfiguration"?
Within my company I have opinions that oppose each other.
 1) physically change cables that are connected
 2) change the configuration settings (e.g., mode select)
