vfc20 3 0x6f7703 50:05:08:b2:00:71:c8:c2 50:05:08:b2:00:71:c8:c0
fc2/3 3 0x6f7704 50:06:0e:80:03:29:61:0f 50:06:0e:80:03:29:61:0f
Both FC IDs in this setup have the same area 77
assignment.
Note
Step 2
Shut down the HBA interface in the SAN switch.
switch# configure terminal
switch(config)# interface vfc 20
switch(config-if)# shutdown
switch(config-if)# end
Step 3
Verify that the FC ID feature is enabled using the show fcdomain vsan command.
switch# show fcdomain vsan 1
...
Local switch configuration information:
State: Enabled
FCID persistence: Disabled
If this feature is disabled, continue to the next step to enable the persistent FC ID.
If this feature is already enabled, skip to the following step.
Step 4
Enable the persistent FC ID feature in the SAN switch.
switch# configure terminal
switch(config)# fcdomain fcid persistent vsan 1
switch(config)# end
Step 5
Assign a new FC ID with a different area allocation. In this example, replace 77 with ee.
switch# configure terminal
switch(config)# fcdomain fcid database
switch(config-fcid-db)# vsan 3 wwn 50:05:08:b2:00:71:c8:c2
fcid 0x6fee00 area
Step 6
Enable the HBA interface in the SAN switch.
switch# configure terminal
switch(config)# interface vfc 20
switch(config-if)# no shutdown
switch(config-if)# end
Step 7
Verify the pWWN ID of the HBA by using the show flogi database command.
switch# show flogi database
