First part of this series I showed you how to install the exchange server and what are the pre-requisites to install the exchange 2010
In this part I will show you how to create DAG, how to add the member servers to DAG and how to configure the DAG network.
Create the new DAG:-
Go to the exchange management console, in organization Configuration click the Mailbox sub menu
From the Database Availability Group tab right-click and create new Database Availability Group
Type the DAG name and File share Witness server name and path of the Witness Directory.
Click New to create the new DAG
Now we are successfully configured the new Database Availability Group named DAG01.
Click Finish to complete the configuration
In the below screenshots we can see the newly created DAG name (DAG01), Witness server name and Witness Directory path
Adding Member server to DAG:-
Now I am going to add the member servers to the newly created DAG, this process will also install and configure the failover clustering in the servers.
For that right-click the DAG01 and click the Manage Database Availability Group Membership
Then click Add button to add the member servers to DAG01, this will give you the server selection window for adding the servers to DAG01
Select the appropriate server from the selection window, in my example I have only 2 servers with mailbox role installed.
Click ok to complete the selection of Servers
Now we can see both Mailbox server added to the Database Availability Group Membership window.
Click Manage to add both servers to DAG01
Now we are successfully completed adding the server to DAG01
Click finish to exit the Database Availability Group Membership window.
The below mentioned screenshot we can see the we can see the member server of the DAG01, network interfaces of the both servers and the status of the interfaces
Assigning the Virtual IP address to DAG:-
In the below screenshot we can see that there is no IP assigned for the DAG01
We have to configure the Virtual IP address for the DAG01
This is the PowerShell command for configuring the DAG IP address
Set-DatabaseAvailabilityGroup DAG01 –DatabaseAvailabilityGroupIpAddresses 192.168.1.165
Now we can see that the IP address (192.168.1.165) is assigned to the DAG01, also a computer account is created in the active directory
This the file share witness folder which is created by the DAG
The below mentioned screenshot we can see the status of the DAG01 nodes, IP address of the DAG01 and the Witness directory path in Failover Cluster Manager.
In the next parts i will show you how to create the database copy and how to test the DAG
