both switches will flash to show the affected ports. Refer to the ”Set Config
Command” on page A-31 for information about the switch keyword and the
Domain ID Lock and Principal Priority parameters.
If you connect a new switch to an existing fabric with its domain ID unlocked, and
a domain conflict occurs, the new switch will isolate as a separate fabric.
However, you can remedy this by resetting the new switch or taking it offline then
back online. The principal switch will reassign the domain ID and the switch will
join the fabric.

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. SANbox 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 FDMI tab, and click the Information (i) button in the Details column of the
FDMI data window. The Detailed FDMI Display dialog displays the specific
information for that device. Refer to ”Detailed FDMI Display Dialog” on page 4-9
for more information.
Note: Domain ID reassignment is not reflected in zoning that is defined by
domain ID and port number pair. You must reconfigure zones that are
affected by domain ID reassignment.
