I/O Stream Guard
The I/O Stream Guard feature suppresses 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 options:
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.
Refer to “Device Scan” on page 5-14.

Device Scan
The Device Scan feature queries the connected device during login for FC-4
