Exchange Server 2013: Deploying a new DAG – Adding Mailbox Databases copies and failover
Boa Tarde meus amigos,
So far in our series we got to the point of having the DAG configured and the servers ready for the final component: the Mailbox Database!!
In order to create a Mailbox Database and enable replication for this new database in our DAG these following steps can be used:
Logged on the EAC, let’s click on servers item on the left and then on databases. Let’s click on Add icon button and in the new wizard let’s name the new database (in our example here MVD-DB02) and let’s click on browse… the list of servers will contain the server names and on the third column if they are part of a DAG, as shown in the figure below. Click on the desired server to be the first one that will host our new database and click on ok.
Back to the initial page, let’s fill out the file path information using the drive letter that is shared among all members of the same DAG (in our post series is the drive M:) and finally click on save.
So far the procedure to create a Database is exactly the same of any other database. Here is the difference, as soon as you create the new database in a member of the DAG, you can click on More icon (…) and then click on Add database copy
Now we are talking, click on browse and the list of servers listed will be smaller then your servers, right? Well, that happens because you can only replicate that Mailbox Database to other members of the same DAG. Select the server member that you want to host a copy of the Mailbox database and click on OK. We can also define the activation preference however we are going to leave default settings and then click on Save.
The process may take a few moments and click Close.
As result of our operation we will see the Database listed and on the column server with copies both DAG members will be listed. If we look at the right side we will get more information about this database such as Active Server, member servers, check replication details, suspension, removal and so forth.
Moving the Mailbox Database to another DAG member…
Let’s click on the Mailbox Database on the list of database, and let’s click on activate and click on yes on the dialog box that will be displayed. Bear in mind that activate link only will be available on passive copies of the database.
