About RSCN Information
The Registered State Change Notification (RSCN) is a Fibre Channel service that informs hosts about
changes in the fabric. Hosts can receive this information by registering with the fabric controller
(through SCR). These notifications provide a timely indication of one or more of the following events:
•
•
•
•
•
Apart from sending these events to registered hosts, a switch RSCN (SW-RSCN) is sent to all reachable
switches in the fabric.
The switch sends an RSCN to notify registered nodes that a change has occurred. It is up to the nodes to
Note
query the name server again to obtain the new information. The details of the changed information are
not delivered by the switch in the RSCN sent to the nodes.
