Configuring Persistent FC IDs

To configure persistent FC IDs, follow these steps:
Command
Step 1
switch# config t
switch(config)#
Step 2
switch(config)# fcdomain fcid database
switch(config-fcid-db)#
Step 3
switch(config-fcid-db)# vsan 1000 wwn
33:e8:00:05:30:00:16:df fcid 0x070128
switch(config-fcid-db)# vsan 1000 wwn
11:22:11:22:33:44:33:44 fcid 0x070123 dynamic
switch(config-fcid-db)# vsan 1000 wwn
11:22:11:22:33:44:33:44 fcid 0x070100 area

About Unique Area FC IDs for HBAs

Note Only read this section if the HBA port and the storage port are connected to the same switch.
Some HBA ports require a different area ID than 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.
Switches in the Cisco MDS 9000 Family 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. The procedure in this example uses a switch domain of 111(6f hex). The HBA port connects to
interface fc1/9 and the storage port connects to interface fc 1/10 in the same switch.

Configuring Unique Area FC IDs for an HBA

To configure a different area ID for the HBA port, follow these steps:
Obtain the Port WWN (Port Name field) ID of the HBA using the show flogi database command).
Step 1
switch# show flogi database
