Go to the primary/active unit and post the complete output to the command "sh redundancy detail".

If the primary unit is still down, please console into it and reboot it. Post the entire boot-up process.

Hello Leo ;

After rebooting the Primary and Seconadry WLC;  the seconadry become the Primary and the Primary become Secondary and HA get UP as you can screenshot .

The secondary is now the active.
What happens if you reboot the secondary? Does the primary become active?
