Is My Exchange DAG OK?
Posted on 2015-02-01
I have a DAG set up by others.
In the EMC under Server Config.> Mailbox>DatabaseCopies I find both DB's by choosing either DAG member. Choosing DAG1, Is Active is set to FALSE for both DBs. It's set to FALSE when I look under DAG2. My thought was that each DB shold be active on one DAG member.
Going to powershell and running Get-MailboxDatabaseCopyStatus *
I see that both DB's are listed under each DAG member, Under DAT1 tye are listed at Mounted, under DAG2 they are listed as Healthy. Content Index States are listed as healthy for all.
Test-ReplicationHealth came back healhty for both DAGs.
Is my DAG configured correctly? Do I need to dig further?
My goal is first, be sure that if a DAG member goes down, mailboxes remain available. Second is load balance according to best practices so my exchange environment is healthy.
To me I would think that the EMC should show each DB to be active on one DAG member, so this makes me uneasy. Hopefully I'm misunderstanding something.
