Description (partial)

Symptom:
Configuration loss and other forwarding problems can be seen in Nexus 5000/5500/5600/6000 if switch
was upgraded by changing boot variables and reload. 

This bug is filed to remove the "Upgrading a Dual-Homed FEX Access Layer" section from documentation, which suggests changing boot variables manually and to insert a warning not to do this instead:
