Hey guys,
I've been trying to look for an answer for this for some time but I haven't been able to find anything.
I have currently a 4 node DAG with around 30DBs.
I don't know why but every now and then the databases are being automatically failed over to another node.
I initially detected this behavior on servers that were backed up.
But now I am only backing up 1 of the DAG members and still the databases being hosted on the others failover to other nodes every now and then.
I am trying to detect the reason for this behavior because I think it could be storage performance issues, but still not 100% sure.
So I wanted to know if there is an event log somewhere in Exchange that says when an Active Database is being failed over to another node.
I did some research and found someone saying to look for event ID 102 but it doesn't really show this information.
I also tried looking for details on the High availabilty logs for exchange but didn't find anything.
Any ideas on how to look for this?
Thank you!
