  • Are you doing an FC port-channel or two individual links?  (not that that is the issue I don't think).  Can you paste in your N5k config.  For me your N5k config should look something like this: (not forgetting aswell you need 'feature npiv' on your N5K.

     

    feature npiv

    interface fc x/y

    switchport mode f

    switchport trunk mode on

    switchport trunk allowed vsan 101

    no shut

     

    vsan database

    vsan 1 interface fc x/y

     

    Now, if you don't want to do trunking (you don't actually need it if only passing a single vsan), then it should look like this:

     

    N5K:

    feature npiv

    int fc x/y

    switchport mode f

    no shut

    vsan database

    vsan 101 interface fc x/y

     

    UCS:

    int fc x/y

    switchport mode np

    no shut

    vsan database

    vsan 101 interface fc x/y

  • hi

    thanks for your reply, i have done mistake by using npv mode on n5k. after correcting this its working now.
