High Avaibility swap from secondary to primary
my problem is the following
i've two TZ-400 in High avaibility mode
The TZ-400 A is the primary and the TZ-400 B is the secondary one.
Everything works fine but one day, for any reason, the secondary B has take effect. Maybe because the primary A has a little problem.
But now that the Primary A works perfectly, why is it allways the Secondary B Active.....
Thank you very much
Welcome to the SonicWall community.
There is an option called Preemption under MANAGE | High Availability | Settings. If this is disabled, even when the primary is back up and operational the failover does not take place.
We usually suggest it be turned OFF as the hardware, settings, firmware, etc is identical for both the devices and this will unnecessarily trigger an additional failover.
If you wish the primary to be active whenever available, you can have this option enabled.

Thank you very much for your answer.
I'll try it next month when i'll be on place In Paris.
If it doesn't works, i'll be back.
Sure. Let us know how it goes 😀
