About Unique Area FC IDs for HBAs

Note Only read this section if the Host Bus Adapter (HBA) port and the storage port are connected to the same
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:
Procedure
Step 1 Obtain the port WWN (Port Name field) ID of the HBA using the show flogi database command.
switch# show flogi database
------------------------------------------------------------------------------------------
INTERFACE
------------------------------------------------------------------------------------------
vfc10/1
fc2/3
Note
Step 2 Shut down the HBA interface in the Cisco Nexus 5000 Series switch.
switch# configuration terminal
switch(config)# interface vfc20/1
OL-16597-01
Command or Action
switch(config-fcid-db)# vsan vsan-id
wwn 11:22:11:22:33:44:33:44 fcid
fcid dynamic
switch(config-fcid-db)# vsan vsan-id
wwn 11:22:11:22:33:44:33:44 fcid
fcid area
VSAN FCID
3 0x6f7703
3 0x6f7704
Both FC IDs in this setup have the same area 77
assignment.
Purpose
Configures a device WWN (11:22:11:22:33:44:33:44)
with the FC ID 0x070123 in the specified VSAN in
dynamic mode.
Configures a device WWN (11:22:11:22:33:44:33:44)
with the FC IDs 0x070100 through 0x701FF in the
specified VSAN.
Note To secure the entire area for this fcdomain,
assign 00 as the last two characters of the FC
ID.
