Description
The I/O Stream Guard option 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 change, click
in the field, and select an option from the drop-down list. The options are:
• Enable–Suppresses the reception of RSCN messages from ports for
which I/O Stream Guard is enabled.
• Disable–Enables free transmission and reception of RSCN messages.
• Auto–Suppresses the reception of RSCN messages when the port is
connected to an initiator device with an HBA. The default is Auto.
The Device Scan feature queries the connected device during login for
FC-4 descriptor information. Disable this option only if the scan creates a
conflict with the connected device.
