About Unique Area FC IDs for HBAs
Only read this section if the Host Bus Adapter (HBA) port and the storage port are connected to the same
Note
switch.
Some HBA ports require a different area ID than for the storage ports when they are both connected to
the same switch. For example, if the storage port FC ID is 0x6f7704, the area for this port is 77. In this
case, the HBA port's area can be anything other than 77. The HBA port's FC ID must be manually
configured to be different from the storage port's FC ID.
Cisco Nexus 5000 Series switches facilitate this requirement with the FC ID persistence feature. You can
use this feature to preassign an FC ID with a different area to either the storage port or the HBA port.
Configuring Unique Area FC IDs for an HBA
The following task uses an example configuration with a switch domain of 111(6f hex). The server
connects to the switch over FCoE. The HBA port connects to interface vfc20/1 and the storage port
connects to interface fc2/3 on the same switch.
To configure a different area ID for the HBA port, perform this task:
Obtain the port WWN (Port Name field) ID of the HBA using the show flogi database command.
Step 1
switch# show flogi database

vfc10/1
fc2/3
Note
Shut down the HBA interface in the Cisco Nexus 5000 Series switch.
Step 2
switch# configuration terminal
switch(config)# interface vfc20/1
switch(config-if)# shutdown
switch(config-if)# end
switch#
Verify that the FC ID feature is enabled using the show fcdomain vsan command.
Step 3
switch# show fcdomain vsan 1
...

If this feature is disabled, continue with this procedure to enable the persistent FC ID.
If this feature is already enabled, skip to
Step 4
Enable the persistent FC ID feature in the Cisco Nexus 5000 Series switch.
switch# configuration terminal
switch(config)# fcdomain fcid persistent vsan 1
