How to create new port channel on auto-lag enabled switch when ports are already in portmode hybrid?

All,

  I am totally new to dell switches (cisco background) and have been asked to create a port channel split over a pair of existing dell aggregator enclosure switches. All the other ports which are connected to the servers except the ports in question I am trying to configure are in port channel.

I have read that they cannot be in a port mode to do auto-lag port channel but I seem to be totally failing to workout how to:

1) Create a new port channel

2) Take the existing ports out of the port mode

3) Add the port to the new port channel.

When I try to create a new port channel interface  I get as shown below

agg1(conf)#int po16
Error: Command allowed only for uplink Lag.

The port(s) I am try to change currently have this config:

interface TenGigabitEthernet 0/1
 mtu 12000
 portmode hybrid
 switchport
 vlan tagged 220,223,950
 flowcontrol rx on tx off
!
 protocol lldp
  advertise management-tlv management-address system-name
  dcbx port-role auto-downstream
 no shutdown

And I am trying to get them in to the same config as this example port on the same switch (with a different port channel unique to the t0/1 port on both dell aggregators)

interface TenGigabitEthernet 0/2
 mtu 12000
 vlan tagged 220,223,950
 flowcontrol rx on tx off
!
 port-channel-protocol LACP
  port-channel 1 mode active
!
 protocol lldp
  advertise management-tlv management-address system-name
  dcbx port-role auto-downstream
 no shutdown

which is then tied to :


!
interface Port-channel 1
 mtu 12000
 portmode hybrid
 switchport
 vlt-peer-lag port-channel 1
 no shutdown
 link-bundle-monitor enable

I am sure I must be missing some top level command somewhere that allow me to configure but I seem to be going round in circles and the only guides seem to be coming from a fresh switch setup (and concerned I am going to impact the setup of the other ports.

Any pointers would be greatly appreiciated
