Chapter 9 Troubleshooting N-Port Virtualization Common Problems with NPV Send documentation comments to [email protected] Step 2 Enter the no shutdown command on the same server interface. NPIV Is Not Enabled If NPIV is not enabled on the NPV core switch: Step 1 Enter the show npv status command to check the status of the link: 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 Step 2 If the state is "Failed" with the reason "NPIV is not enabled in upstream switch," then you must enable 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: Step 1 Enter the show npv status command to check the status of the link. 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.
