    Switch 2, previously with Role Backup, is now showing at Role Master. Switch 1 is still actively the Master. All ports on Switch 2 are now showing as Ready. Devices connected to Switch 2 are no longer responding.

    Can you send a "show switch" and "show slot"?

    Show switch displays only switch 1. Here's output from show slot:
    Slot-1 SJCO-DMZ-X460-48T-2.23 # sh slot

    Can you send a "show slot 2 detail" and also what version of code is running on this stack? The "show switch" should provide that with the patch.

    I am sure a reboot of slot 2 will resolve this. As for why there might be something in the logs. Do we know when this happened?

    On the other side I would recommend upgrading this stack to the latest of 16.2. In 15.4 some changes were made to the stacking libraries in the code and it prevented these dual master situations.

    Rebooting the slot resolved the issue. It's back online. Once again, thanks for the help.

    Log states Backup Node Down. Log entries go back only to 06:00 PST this morning. That's the first indication.
    I'll reboot Node 2. Thanks very much for responding.
