Description (partial)

Symptom:
A Cisco UCS chassis with a 2104 or 220x IOM that comes up without all the links operational. The fex output indicates "Identity-Mismatch" for a port and "unsupported-connectivity" in the logs.

Conditions:
This happens when an IOM is replaced during normal operation. If a like for like replacement of an IOM is done where the amount of cables connected is not the same as the chassis discovery policy, the system can end up on an error state. Even though the chassis itself was not replaced, just the component.
