I've setup a vNIC for one of our blade servers with failover enabled for redundancy. In order to test the FI failover for the vNIC I go ahead and disable the upstream port for FI-A. This should tell UCS to failover to FI-B with little to no downtime. This does not happen as it should. Looking at the equipment's VIF paths it seems as even though the upstream port for FI-A is disabled the virtual circuit is still showing as a link state of up. Any ideas why the failover might not be working as it should? Thanks for the help.

So you have disabled all uplink ports on FI-A that carry the vlans related to the VNIC you are trying to test fail over for?
If you have a typical VPC type setup, you'll probably need to disable ports on both upstream switches going to FI-A,,, or just disable the uplink port-channel on FI-A itself.
It's also possible you have a network control policy applied to the vnic/vnic template, that has the 'action on uplink failure' set to 'error' instead of 'link down'
The default setting is linkdown.
