Description (partial)

This issue is seen when a UCSM server port connected to a newly added chassis fails to come up and Chassis discovery does not proceed.

This issue is seen when the user performs the following configuration steps:

1. Does a "remove chassis" operations on a chassis that is discovered but the IOMs are not currently operational or are disconnected.

2. Adds another chassis to UCSM by connecting the IOMs to a new or existing UCSM server port.

After step 2, the server port connected to the new chassis/IOM goes to down state with reason as  'FEX identity mismatch'.
