Enter the no shutdown command on the same server interface.

NPIV Is Not Enabled

If NPIV is not enabled on the NPV core switch:
Enter the show npv status command to check the status of the link:
Step 1
switch# show npv status
npiv is enabled
External Interfaces:
====================
Interface: fc1/2, VSAN: 1, FCID: 0xe00200,
State: Failed(NPIV is not enabled in upstream switch)
Number of External Interfaces: 1
If the state is "Failed" with the reason "NPIV is not enabled in upstream switch," then you must enable
Step 2
NPIV on the core NPV switch.
The NPV core switch is defined as an upstream switch on which NPIV is enabled. The NPV core switch
receives traffic that is passed to it from a downstream switch that has NPV enabled on it. A switch that
is in NPV mode does not switch traffic; instead, it passes traffic to the upstream NPV core switch on
which NPIV is enabled.
After NPIV is enabled on the core NPV switch, the port should automatically come up (unless there are
other issues).

VSAN Mismatches

If there is a VSAN mismatch in VSAN for the core NPV switch ports:
Enter the show npv status command to check the status of the link.
Step 1
switch# show npv status
npiv is enabled
External Interfaces:
====================
Interface: fc1/1, VSAN: 1, FCID: 0x110000, State: Failed(Mismatch in VSAN for this
upstream port)
Number of External Interfaces: 1
Step 2 If the state is "Failed" with the reason "Mismatch in VSAN for this upstream port" then the external
interface is configured to have different VSAN on both ends.
