Series Hardware Installation Guide. The interfaces on this new CSM will have brand new nWWN and
pWWNs.

Replacing a CSM in a Different Slot

If a CSM is replaced by another CSM in a different slot on the same or different chassis, and the same
nWWNs and pWWNs are to be retained, follow this process.
Document the nWWN and pWWN values for the CSM before removing it.
Step 1
Remove the CSM from the slot as directed in the Cisco MDS 9216 Switch or the Cisco MDS 9500 Series
Step 2
Hardware Installation Guide.
Use the following command to erase the nWWNs and pWWNs from the original slot. Issue the command
Step 3
when the module has already been removed or when it is in the powered-down state.
switch# svc purge-wwn module <slot-num>
The old nWWNs and pWWNs will be lost from the system and never reassigned for any purpose in that

Replace the new CSM in the desired slot as directed in the Cisco MDS 9216 Switch or the Cisco MDS
Step 4
9500 Series Hardware Installation Guide.
Wait for the module to initialize.
Step 5
Configure the VSAN for the initiator, target, and management N-ports to match the replaced nodes:
Step 6
switch# config t
switch (config)# interface svc
switch (config-if)# initiator vsan
switch (config-if)# target vsan
switch (config-if)# mgmt vsan
Step 7 Set the nWWN and pWWN values for the two interfaces within the module with the following
commands:
switch (config-if)# shutdown
switch (config-if)# nwwn
switch (config-if)# initiator vsan
switch (config-if)# target vsan
switch (config-if)# mgmt vsan
Tip The related SVC interface must be shut down before setting the WWNs.
Step 8 Reload the CSM using the reload module slot-number command for the new nWWNs to take effect.
