HA flop on manual firmware upgrade to 19.5

I did have same issue. HA Cluster has been updated properly. But every couple minutes appliances flipping one another. 

I have disabled HA on active device, it did not resolve issue. I had to power off faulty one. HA Status was showing one of device is faulty. 

Do you have exact same manufactured year (hardware version) on both devices? 

In my past experiences: When a major update/update implemented, if device hardware version are not same, this causes problem on HA Environments.

Hello there,

Can you send the Access ID to your device via PM, so we can confirm if this matches the same NC-111325 or if something else might be causing this.

Did you create a case for this by any chance? if so can you share it. 

Regards,

Hi there yes. We have create a case. An support technician is trying to deal with it. This is second time happening to us when we deal major updates. 

Hello there,

Can you share the Case ID here or via PM? If you haven't enable the Access ID, please enable it and share it via PM.
