Port-Channel Resources Unavailable

I am trying to create a new port-channel on Cisco 9710 for UCS to channel 20 but when adding more than one port (fc1/40) I receive the following error.

command failed: port not compatible [Resources Unavailable]. 

port-channel 20

    Administrative channel mode is active

    Operational channel mode is active

    Last membership update failed: port not compatible [Resources Unavailable]

    1 port in total, 0 ports up

    Ports:   fc1/38   [down]

As seen, port 38 is a member. 

fc1/38 is down (Link failure or not-connected)

npiv and fport-channel-trunk features enabled on 9710 ?   (Note, i don't have experience with 9700, 9500 only)

Hi,

try to enable the force option; then if moving a port to a port channel, the port will learn the configuration from the parent device. Otherwise all port settings must match the port channel setting's.

I have tried using the force option.  In making changes, I ether get a resource error or port mode error. I had not tried using device manager, but just did and got the same error.

Was able to get it to work after removing the port-channel and re-creating.  I changed the switchport mode to F on the port-channel itself.  Stil not sure why it would not work as Auto.

int port-channel 20

switchport rate-mode shared

switchport trunk mode on

switchport trunk allowed vsan all

switchport mode f

channel mode active

Vsan database

Vsan 12 Interface port-channel 20

Exit

added interfaces

sh vsan membership

Oh, that's two I always forget to enable. Gets me puzzled for hours and then I remember, I didn't put

  • feature npiv
  • feature fport-channel-trunk

in that (most of the time) new switch.
