Hi, 

After a power outage and issues with the UPS, we see an issue with failover. 

The first thing I noticed when login in to the CLI of the secondary firewall, was this message - "You have logged in while system startup is in progress. Please wait, some feature may be unavailable until startup is complete". I still see this message, even after 3 days. A rebbot of the firewall didn't helped either. I am not sure this is related to the failover issue or another separate issue. Anyway, the failover doesn't work on the secondary firewall and the state is "Failover Off (pseudo-Standby)" A "show failover history details" gives me the following output

==========================================================================From State To State Reason==========================================================================12:57:25 UTC Aug 19 2022Not Detected Negotiation No Error

At first I thought I should break the failover from FMC and re-create it, but when trying to break it, I received the following message:

Is it safe to go on with breaking the failover or should I contact TAC? I'm also curious of the message: "You have logged in while system startup is in progress. Please wait, some feature may be unavailable until startup is complete"  Anyone know how to fix this?

Thanks
