Fabric Device Management Interface
Fabric Device Management Interface (FDMI) provides a means to gather and 
display device information from the fabric, and allows FDMI capable devices to 
register certain information with the fabric, if FDMI is enabled. SANsurfer Switch 
Manager will report any and all FDMI information reported by the entry switch, if 
FDMI is enabled on the entry switch. To view FDMI data, FDMI must be enabled 
on the entry switch and on all other switches in the fabric which are to report FDMI 
data.
FDMI is comprised of the fabric-to-device interface and the application-to-fabric 
interface. The fabric-to-device interface enables a device’s management 
information to be registered. The application-to-fabric interface provides the 
framework by which an application obtains device information from the fabric. Use 
the FDMI HBA Entry Limit field on the Switch Properties dialog to configure the 
maximum number of HBAs that can be registered with a switch. If the number of 
HBAs exceeds the maximum number, the FDMI information for those HBAs can 
not be registered. 
Use the FDMI Enabled radio button on the Switch Properties dialog to enable or 
disable FDMI. If FDMI is enabled on an HBA, the HBA forwards information about 
itself to the switch when the HBA logs into the switch. If FDMI is enabled on a 
switch, the switch stores the HBA information in its FDMI database. Disabling 
FDMI on a switch clears the FDMI database. If you disable FDMI on a switch, then 
re-enable it, you must reset the ports to cause the HBAs to log in again, and thus 
forward HBA information to the switch. 
To view detailed FDMI information for a device, open the topology display, click 
the Devices tab, and click the Information (i) button in the Details column of the 
Devices data window. The Detailed Devices Display dialog displays the specific 
information for that device. Refer to 
 for 
more information.
