FDMI

The following example shows how to display the name server database and statistical information for a
specified VSAN:
switch# show fcns database vsan 1
VSAN 1:
--------------------------------------------------------------------------
FCID
--------------------------------------------------------------------------
0x030001
0x030101
0x030200
0xec0001
Total number of entries = 4
The following example shows how to display the name server database details for all VSANs:
switch# show fcns database detail

FDMI
Cisco Nexus 5000 Series switches provide support for the Fabric-Device Management Interface (FDMI)
functionality, as described in the FC-GS-4 standard. FDMI enables management of devices such as Fibre
Channel host bus adapters (HBAs) through in-band communications. This addition complements the existing
Fibre Channel name server and management server functions.
Using the FDMI functionality, the switch software can extract the following management information about
attached HBAs and host operating systems without installing proprietary host agents:
• Manufacturer, model, and serial number
• Node name and node symbolic name
• Hardware, driver, and firmware versions
• Host operating system (OS) name and version number
All FDMI entries are stored in persistent storage and are retrieved when the FDMI process is started.

RSCN

The Registered State Change Notification (RSCN) is a Fibre Channel service that informs hosts about changes
in the fabric. Hosts can receive this information by registering with the fabric controller (through a State
Change Registration (SCR) request). These notifications provide a timely indication of one or more of the
following events:
• Disks joining or leaving the fabric
• A name server registration change
• A new zone enforcement
