Suppressing RSCN Messages

The I/O Stream Guard feature suppresses Registered State Control Notification (RSCN) messages on a port basis. When enabled, I/O Stream Guard port suppresses the generation of RSCN messages for normal fabric events such as plugging and unplugging ports, and name server registrations. I/O Stream Guard also ensures that the port is not returned in any N_Port name server queries.

 

To suppress RSCN messages, do the following:

 

1. Select one or more ports in the faceplate display.

2. Open the Port menu and select Port Properties to open the Port Properties dialog.

3. In the I/O Stream Guard Enable area, click the Enable radio button.

4. Click the OK button to save the change and suppress RSCNs for the selected ports.
