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 switchconfig if sh int fc. InitializingHardware is Fibre Channel, SFP is short wave laser wo OFC SNPort WWN is 2. 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 switchconfig if sh npv statusnpiv is disableddisruptive load balancing is disabled. External Interfaces Interface fc. State FailedNPIV is not enabled in upstream switchInterface fc. State FailedNPIV is not enabled in upstream switchInterface san port channel 2. State Down If NPIV is disabled, then enable NPIV on the core switch. Example switchconfig feature npiv Server interface does not come up and NPV upstream port not available message appears. A server port connected to the NPV edge switch does not come online, and the show interface command indicates a status of NPV upstream port not available. Possible Cause. The upstream NPPorts and the downstream server FPorts on the NPV edge switch may not be in the same VSAN. Example switch sh int fc. NPV upstream port not availableHardware is Fibre Channel, SFP is short wave laser wo OFC SNPort WWN is 2. Admin port mode is F, trunk mode is offsnmp link state traps are enabled. Port vsan is 9. 9Receive data field Size is 2. Solution. Check the VSAN membership of the upstream port and the server port. Example switch show vsan membershipvsan 1 interfaces fc. In the example above, notice that the upstream ports fc. VSAN 1, and the server ports fc. VSAN 9. 9. Move the NP ports on the NPV edge, and the F ports on the NPIV core into the same VSAN as the server ports. Example switchconfig vsan databaseswitchconfig vsan db vsan 9. Traffic on fc. 11. Do you want to continue Traffic on fc. Do you want to continue Note Alternatively, if the NPIV core and NPV edge switch are FPort Trunking capable switches, then that would be the recommended configuration. Uneven load balancing on the NPV NP ports. An examination of NP upstream ports that are members in the same VSAN reveals that uneven load balancing is occurring. Possible Cause. This may be normal and a direct result of the default SIDDID load balancing that is done before the Nexus 5. N1 release. Solution. If the upstream switch is an MDS switch that is running 4. NPV FPort Trunking capable switch, the preferred configuration would be to run the FPort Trunking Port Channeling feature. Example NPIV core pod. In this example, fc. Do the same operation on the switch at the other end of the port channel, then do no shutdown at both ends to bring them up. Example pod. 3 9. Example NPV Edge pod. In this example, fc. Do the same operation on the switch at the other end of the port channel, then do no shutdown at both ends to bring them up. Example pod. 7 5. Server on downstream NPV edge switch does not login to the fabric. The server connected to the downstream NPV edge switch does not log in to the fabric. Possible Cause. The server on the downstream NPV edge switch does not log in to the fabric, andor you see a waiting for FLOGI message. Example switch show npv statusnpiv is enabled. Server Interfaces Interface fc. VSAN 1, NPIV No, State Waiting for FLOGI Solution. Verify the configuration of both the NPV edge and core switches. If you are not running the FPort trunking feature, then verify that there are no VSAN mismatches and that the server ports, NPV NP ports, NPIV Core FPorts, and storage ports are all in the same VSAN and all are online. If the configuration is correct and you can determine where the problem might be, you can collect an Ethanalyzer trace and verify that the Fabric Login FLOGI frame is being received and sent to the NPIV core as a Fabric Discovery FDISC command. Example Ethanalyzer trace switch ethanalyzer local sniff interface inbound hi display filter Capturing on eth. Recreate the problem by flapping the NPV attached server port. The trace will be written to bootflash and can be copied off the switch by using the following copy bootflash ftp After the trace has been copied, you can now open and verify the flow using Wireshark. Example normal NPV login flow Server FLOGI NPV Edge Switch. Fabric Login frame FLOGINPV Edge Switch FDISC NPIV Core Switch. Fabric DISCovery frame maps parameters from Server FLOGINPV Core Switch Accept NPV Edge Switch. NPIV Core assigns an FCID with the Accept to the FDISC from NPV Edge Switch. NPV Edge Switch Accept Server Accept to original Server FLOGI with FCID assigned from NPIV Core Switch. Locating exact port that server is physically attached to. NPIV switches lose visibility into the physical port that a downstream NPV connected server is attached to. The following process can be used to identify that physical port. Possible Cause. When you have an NPIV core switch that has several downstream NPV edge switches attached, you might want to locate the exact port that a server is physically attached to. Solution. Identify the PWWN of the server and the corresponding switch that it is attached to. Example NPIV Coreconfig if show flogi database fc. In the example, the server is identified by this address fc. Identify the IP address of the NPV edge switch. Example NPIV Coreconfig if sh fcns database npv. VSAN 1. 00 2. 0 6. Telnet to the NPV edge switch. Example NPIV Coreconfig if telnet 1. Identify the PWWN of the server. Example switch NPV Edge show npv flogi table vfc. If the interface is a FCo. E VFC interface as shown in the previous example, use the show interface vfc. VFC is physically bound to. VSANs stuck in initializing state after configuring the 4. N1 FPort trunking feature. Using the show interface command of the FPort trunking port channel or trunking member of the port channel indicates that certain VSANs are in an initializing state and do not come online. Possible Cause. After configuring the 4. N1 FPort Trunking feature, VSANs on the trunk ports appear to be stuck in an initializing state. Example switchconfig if sh int fc. Hardware is Fibre Channel, SFP is short wave laser wo OFC SNPort WWN is 2. Admin port mode is NP, trunk mode is onsnmp link state traps are enabled. Port mode is TNPPort vsan is 1. Speed is 4 Gbps. Transmit B2. B Credit is 1. 6Receive B2. B Credit is 1. 6Receive data field Size is 2. Beacon is turned off. Belongs to san port channel 2. Trunk vsans admin allowed and active 1,9. Trunk vsans up 1,9. Trunk vsans isolated Trunk vsans initializing 2. Under the Trunk Failures tab of Fabric Manager, you might also see the trunk VSAN listed. However, this may be normal. If no downstream devices are logged in for a particular VSAN, that VSAN stays in initializing state. Solution. For the VSANs that you are working with, verify by using the following command Example switch show npv flogi table fc. Spo. 20. 0fc. 28 9. Spo. 20. 0Total number of flogi 2. In this example, no devices are logged into VSAN 2.
