In this article, I am going to give in the installation and configuration of VMware vCenter in AAG(Always ON) Database.
Steps to Configure:
1. Install the Microsoft Window 2012(Enterprise or datacenter Edition) Server on 3 Nodes(Node1.local.domain , Node2.local.domain,Node3.local.domain).
2. Install the Microsoft Failover Clustering Service in all the 3 Nodes (Server Manager -> Add Roles ->Select Failer Over Cluster and .Net 3.5 Service -> Install-> Finish) .
3. GO to Administrative Service -> Failover Cluster -> Create Cluster Wizard ->Add All the Nodes name.
4. Cluster Name "Name to your Cluster" and in the Window Down you need to assign one IP to cluster and Network Details .
5. Click Next and Evaluate all provided input is correct . Click Next to create Cluster..
6. Now Move to other Node and Refresh the Failover Cluster Manager to Reflect the Cluster Detail.
7. you need to validate the Cluster, To Validate Cluster you need to trigger "Validate Cluster" Hyperlink and It should pass all the validation case . You Can Ignore the quram Setting Details.
8. Now you Need to Install the MSSQL database in all the Node by Selecting the First Option "New SQL Server stand-alone Installation " .
9. Once the installation done you can go and create database in the database Manually Like VCDB(Open Managment Studio -> Connect to Datatbase machine -> Right Click on database and create database ).
10. After Creating the database you need to tack the partial or full Backup of that database(Right Click on Database you created in last -> Tasks-> Back Up).
11. Your failover cluster is ready and Now you need to create AAG (Always On high Availability ).
12. Right Click On Always On High Availability Folder Inside the Management Studio and click on "Always On High Availability Wizard" .
13. Give Some name to your AAG Group-> Select the Database you created previously -> Select Replica Node (Node2 and Node3){ Select Automatic failover for 2 Node and Synchronous Commit for 2 Node and readable sector Read intent Only }-> Select End point -> Configure Listener (Optional ) and Finish.
14. Your DB replication will start on other 2 Node.
Now your VCDB is up on the AAG configuration. While doing the VC installation you need give the Cluster IP which we used to configure Failover cluster and your database Details.
This is simple step to configure the vCenter Server in the Microsoft AAG (Always ON Availability ) Database Server.
If you find any Difficulty in Configuration then please post comment. i Will Help to troubleshoot that.
