I/O Stream Guard

The I/O Stream Guard feature suppresses the Registered State Change
Notification (RSCN) messages on a port basis. I/O Stream Guard should be
enabled only on ports connected to initiator devices. To configure the I/O Stream
Guard option using the Port Properties dialog, open the Port menu, and select
Port Properties. Click the radio button that corresponds to one of the following:
Enable: Suppresses the reception of RSCN messages from other ports for
which I/O Stream Guard is enabled.
Disable: Allows free transmission and reception of RSCN messages.
Auto: Suppresses the reception of RSCN messages when the port is
connected to an initiator device with a QLogic HBA. For older QLogic HBAs,
such as the QLA2200, Device Scan must be enabled. The default is Auto.
