Server 2012 NIC Teaming does not work without all adapters 'connected'

I have used Broadcoms BACS suite or the HP Teaming Software to team adapters prior to Server 2012. I am now, unfortunately, required to use the Server 2012 native NIC Teaming function since HP no longer provides, or supports, using their utility with 2012. Not a HUGE issue, but it's not working as the 3rd Party software method has in the past.
I have 2 x QP HPNC365T adapters, for a total of 8 ports. No matter the Teaming method used (Static, LACP, Switch Independant) the Team does not function unless ALL the adapters have link. Is this by design? I would imagine if you are using it for speed/fault tolerance, they would have taken that into consideration. Also, there is no way to create multiple virtual VLAN adapters, as you can with the BACS suite (im not sure if the HP Teaming Software can do this). Am i missing something?

How did you set the ports on the switch side? Are they "Trunked"?

Yes, the ports are trunked. When using LACP, i made sure the ports had LACP enabled on the switch.

Still wondering how the native NIC Teaming in Server 2012 provides 'fault tolerance' or 'link aggregation' if a single port being unplugged/going bad brings the whole team down.

I thought i had previously closed this, my apologies.

This issue is resolved. I'm not sure if the problem was with the OS, but i was able to get it to work.

After installing updates (inadvertently) i deleted and re-created the Team, only this time, i did not attempt to manually set the teaming method. I accepted defaults, and viola - Team up and running. I was not able to reproduce the issue again, even after manually re-creating and setting teaming method. Im not sure if it was a windows update that fixed it, or what. NO settings were changed on my switches, fyi.
