[Venkat] Actually FCP does and ordinary SCSI devices does not
support AEN. When a FC device is added or removed , a LIP ( Lopp
Initilaization Procedure) is initiated. For non-FC devices there is one
version of AEN that allows target initiated event notification.

[Venkat] I agree that bus rescan is a better way. If the SCSI
devices are connected though a SAF_TE processor then we can poll the SCSI
Bus frequently, as the SAF_TE knows about addition and detection.
