I have upgraded the both switches from 5.0.4c to 5.2.2d but I have faced same issue on both after the upgradation. On switch two (secondary) fc2/33 port was shown initializing status and after the reboot switch two fc2/33 status was shown up. Also when I upgraded the switch one (Primary) and found fc2/47 port is now showing initializing status, Please advise.
