    HI 

     

    just did an upgrade to AOS8.2 and when controllers rebooted - the 2. controller never connected to Mobility Master. But it have retained its local configuration (ports, ip addresses) but shows as a master controller rather then connected to Mobility Master

     

    why ? but should I do a factory reset or ??

    Can you check what AOS and partition is currently using ?

    upgrade from AOS 8.1.0.1

    Looking at the upgrade notes I can't find any good gotchas that might lead to this either

    Please open a TAC case and preserve the logs (tar logs tech support from both MM and all MDs in their current state). From here, the fastest fix is to likely either roll back to 8.1.0. from a backup (that you hopefully took before upgrading), or you can wr erase all the MDs and re-point them back to the MM.

    I have backups. And are on the phone with TAC as well. 
    Thanks - will keep you posted :-)

    write erase all

    reconfigure

    all good

    should probably add some more information here, since time was rather limited when posting this originally.

     

    what saved us is that the Mobility Master was up and running. 

    So for each MD we did this: 

    1. write erase all

    2. full-setup and use same IP-address and network settings as originally used/entered into mobility master. 

    3. reboot MD after network was configured and the rest of the configuration were once again pushed from MM

     

    neat :)
