FC IDs
Step 4
Step 5
Unique Area FC IDs for HBAs
Note
Read this section only 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 SAN 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
You can configure a different area ID for the HBA port.
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 and the storage port connects to interface
fc2/3 on the same switch.
Procedure
Step 1
Obtain the port WWN (Port Name field) ID of the HBA using the show flogi database command.

Purpose
To avoid assigning a duplicate FC ID, use
Note
the show fcdomain address-allocation
vsan command to display the FC IDs in
use.
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.
To secure the entire area for this fcdomain,
Note
assign 00 as the last two characters of the
FC ID.
