UCS-B -> NPV 5K -> NPIV MDS

Hi Folks,

I'm having issues getting NPV to work on the nexus 5k.  I believe I have everything configured correctly but the VFC port won't login to the VSAN.

On my N5K I have the following:

interface fc2/3
  switchport mode NP
  switchport trunk allowed vsan 100
  no shutdown

interface Ethernet1/7
  switchport mode trunk
  switchport trunk allowed vlan 10,100
  spanning-tree port type edge trunk
  channel-group 7 mode active

interface port-channel7
  switchport mode trunk
  switchport trunk allowed vlan 10,100
  spanning-tree port type edge trunk
  speed 10000

interface vfc7
  bind interface port-channel7
  switchport trunk allowed vsan 100
  switchport trunk mode on
  no shutdown

The upstream appears ok at the moment.  The interface status for vfc7 is:

vfc7 is trunking
    Bound interface is port-channel7
    Hardware is Ethernet
    Port WWN is 20:06:00:05:73:b6:60:3f
    Admin port mode is F, trunk mode is on
    snmp link state traps are enabled
    Port mode is TF
    Port vsan is 100
    Trunk vsans (admin allowed and active) (100)
    Trunk vsans (up)                       ()
    Trunk vsans (isolated)                 ()
    Trunk vsans (initializing)             (100)
    1 minute input rate 24 bits/sec, 3 bytes/sec, 0 frames/sec
    1 minute output rate 0 bits/sec, 0 bytes/sec, 0 frames/sec
      33 frames input, 2244 bytes
        0 discards, 0 errors
      0 frames output, 0 bytes

    last clearing of "show interface" counters Sat May 30 18:52:05 2015

On the 6248 the vfc bound to the port channel is showing:

DC-6248-1-A(nxos)# sh int vfc 750
vfc750 is trunking (Not all VSANs UP on the trunk)
    Bound interface is port-channel1
    Hardware is Virtual Fibre Channel
    Port WWN is 22:ed:54:7f:ee:df:cc:ff
    Admin port mode is NP, trunk mode is on
    snmp link state traps are enabled
    Port mode is TNP
    Port vsan is 100
    Trunk vsans (admin allowed and active) (1,100-101)
    Trunk vsans (up)                       ()
    Trunk vsans (isolated)                 ()
    Trunk vsans (initializing)             (1,100-101)

My understanding is only one vsan will login but all vsans will work.  In this case I only allow VSAN 100.  I've tried all combinations of VSANs, but adding VSANs doesn't seem to solve the problem.  In essence I only want to allow VSAN 100 on my A side of the fabric.  I had this working fine when the switch wasn't working in NPV mode.

Can anyone provide some guidance on what may be causing my greif? :)

Take Care

Jason
