In a Cisco Data center network, what troubleshooting step would you do first when having a npv issue?
A.
Check to see if npv is enable
B.
Check name server database to see if it recognizes device
C.
Check detail config of FCNS database
D.
Check the show-tech-support detail
NP Uplink ports on NPV edge switch are stuck in initializing state
NP uplink ports connected to the core NPIV switch do not come online and are stuck in an initializing state.
Possible Cause
The core switch might not have been enabled for NPIV.
Example:
switch(config-if)# sh int fc2/2
fc2/2 is down (Initializing)
Hardware is Fibre Channel, SFP is short wave laser w/o OFC (SN)
Port WWN is 20:42:00:0d:ec:a4:3b:80
Admin port mode is NP, trunk mode is on
Solution
•Check the status of the NPV external interfaces.
Check that the NPIV is enabled on the core switch.
Example:
switch(config-if)# sh npv status
npiv is disabled
disruptive load balancing is disabled
External Interfaces:
====================
Interface: fc2/1, State: Failed(NPIV is not enabled in upstream switch)
Interface: fc2/2, State: Failed(NPIV is not enabled in upstream switch)
Interface: san-port-channel 200, State: Down
•If NPIV is disabled, then enable NPIV on the core switch.
Example:
switch(config)# feature npiv
