c7000 network redundancy

[RobertHaight]

I have a check with a pair of Guess, each one is going to a 10 Gig module in separate 5412zl switches.    I have tested the following configuration in ports 17-18 and 23-24.  I have the switches configured so that ports 23-24 are configured as a LACP trunk to the 5412 switches.   The port failover seems to work fine on both switches, but the teamed nics for both Server 2008 R2 and VMware 5.1, if one of the switches is taken offline the failover is not working correctly.

I can't discern if I have a configuration problem in the Sass, the Sass or in the SO and I'm looking for any suggestions on the best way to configure this.

Thanks in advance

You mean you have tried to configure the c7000 ports 23-24 as "trunk-dt", each port to a different 5412?
