I’m actually planning to add a new mailbox server in a different DR site. Ill be adding the mailbox server to the DAG but my concern is the log drive size. Say my DB drive is 300GB and log drive is 60GB. When I add the database copy on a different server, Will i be using the same size for the log drive or should i make the log drive same as 300GB on the DR mailbox server.

Thanks

If you want the new server to replicate the same databases then it will need to be made a member of the same DAG. You can add up to 16 servers to a DAG, and you can add/remove members any time, it is a non-disruptive change.

The DAG members can be in different networks as long as they can communicate with each other. In fact it is recommended when placing DAG members in separate sites that they are in separate IP subnets, instead of stretching one subnet across two sites.

Microsoft has published a document called “The Preferred Architecture” that explains a lot of DAG design best practices.

It is possible to create new DAG or we can able to configure in same DAG

This is exactly what I needed, thanks!

When you run Add-MailboxDatabaseCopy there’s a -SeedingPostponed switch that will prevent the initial seed from occuring. You can then use Update-MailboxDatabaseCopy and specify the source server to seed from.

Another great article. Was curious if you can specify the source server when adding a database copy via powershell? I’ll spare you the details but I don’t want it to seed across our WAN.

Thanks

A timeout occur while communicating with server . A connection cannot be completed within 15 seconds.
I have tried removing the copy by using the CMDLET remove-mailboxdatabasecopy format the drive on my passive server and tried adding again using shell Add-MailboxDatabaseCopy however still facing the same error.

It is a 2 Node Exchange 2013 CU12 DAG on Server 2012 R2 ,on the same Site.

Thanks Paul.

I was actually thinking about the replication traffic between the two sites rather than the testing but the answer appears to be the same. If I create the DAG first, that will allow me to move mailboxes on to it gradually and then have them replicate between the sites as opposed to moving all the mailboxes and then trying to replicate 600gb between them. I just didn’t know if there could be an issue while moving them with the replication traffic for the DAG occurring at the same time.

I should have said that a little better and used a slash instead of “and”. Both servers are multi-role.
