Let me ask this another way. SAN users expect that the LUN list at the initiator side gets updated automatically after a SAN configuration change. How should a SAN system communicate to a SCSI initiator that the LUN list has been changed ? Some FC SAN systems send a LIP after a configuration change to force the initiator to rescan LUNs. But how to inform the initiator about a LUN change for other SCSI protocols ? I'm not sure that it is even possible to report such a change via sense data in case a SAN user first removes all LUNs and after that change adds one or more LUNs.
