I/O StreamGuard
The I/O StreamGuard feature suppresses the Registered State Change Notification (RSCN) messages on a
port basis. I/O StreamGuard should be enabled only on ports connected to initiator devices. To configure
the I/O StreamGuard:
1. Select a switch in the fabric tree.
2. Select one or more ports in the faceplate display.
3. Select Port > Port Properties to open the Properties dialog box.
4. For each port, select one of the following options in the I/O StreamGuard column:
• Enable—Suppresses the reception of RSCN messages from other ports for which I/O StreamGuard
is enable
• 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 an HBA. The default is Auto. See ” Device Scan ” (page 138).
To apply the same value for all selected ports, check the I/O StreamGuard checkbox at the bottom of
the dialog box.
5. Click OK.
Device Scan
The Device Scan feature queries the connected device during login for FC-4 descriptor information. Disable
this parameter only if the scan creates a conflict with the connected device. To configure device scan:

2. Select one or more ports in the faceplate display.
3. Select Port > Port Properties to open the Properties dialog box.
