What I think your looking for is RSCN (Registered State Change notification). Hook that, and then check the name server. This will tell you when ports get added/removed. You can then report luns against lun 0 of all the known target ports. This allows you to transparently detect changes. Otherwise, you run the risk of trapping UA's in the lower level portions of the stack that _REALLY_ need to be propagated to the controlling driver or application.
Thanks for the feedback. Unfortunately sending an RSCN is only possible when using Fibre Channel as transport layer. I'm looking for a solution that also works with other SCSI transports, e.g. iSCSI and SRP.
