Advanced switch properties<br />
FDMI is comprised of the fabric-to-device interface and the application-to-fabric<br />
interface. The fabric-to-device interface enables a device’s management information<br />
to be registered. The application-to-fabric interface provides the framework by<br />
which an application obtains device information from the fabric. Use the FDMI<br />
HBA Entry Limit field on the <strong>Switch</strong> Properties dialog to configure the maximum<br />
number of HBAs that can be registered with a switch. If the number of adapters<br />
exceeds the maximum number, the FDMI information for those HBAs cannot be<br />
registered.<br />
Use the FDMI Enabled option on the <strong>Switch</strong> Properties dialog to enable or disable<br />
FDMI. If FDMI is enabled on an adapter, the adapter forwards information about<br />
itself to the switch when the adapter logs into the switch. If FDMI is enabled on a<br />
switch, the switch stores the adapter information in its FDMI database. Disabling<br />
FDMI on a switch clears the FDMI database. If you disable FDMI on a switch and<br />
then re-enable it, you must reset the ports to cause the adapters to log in again, and<br />
thus forward adapter information to the switch.<br />
To view detailed FDMI information for a device, click the Devices tab, and click the<br />
Information (i) button in the Details column of the Devices data window. The<br />
Detailed Devices Display dialog displays the specific information for that device.<br />
Refer to ”Devices data window” on page 3-19 for more information.<br />
The Advanced <strong>Switch</strong> Properties dialog enables you to set the timeout values and<br />
change to transparent mode. The Advanced <strong>Switch</strong> Properties dialog is available<br />
only for the entry switch. The switch will be taken offline temporarily and then<br />
restored to its original state after the changes are complete.<br />
To open the Advanced <strong>Switch</strong> Properties dialog (Figure 20), open the <strong>Switch</strong> menu<br />
and select Advanced <strong>Switch</strong> Properties. After making changes, click the OK button<br />
to put the new values into effect.<br />
