See part one of this series here: Private Cloud Management with VMM 2012 (Part 1): What's new with System Center Virtual Machine Manager 2012
Before you start deploying cloud and services, we need to first start prepare the fabric.
A cloud can also host HA applications and services and we need to setup a Hyper V cluster to enable that. VMM 2012 has now introduced inbuilt capability of deploying Hyper V Clusters.
Make sure that fabric configuration meets the following prerequisites:
1. Before you deploy Hyper V cluster, you need to add the hosts in the VMM.
Also if you are not using automated storage unmasking, you need to unmask the shared storage on these hosts.
2. Go to Fabric tab and click on Create Clusters
3. Specify the cluster name and provide your domain credentials which has rights to create clusters.
4. Select the host group where your standalone Hyper V hosts are located.
5. Select the hosts which you would like to be part of the cluster and click ADD
6. Ensure that the Network cards are picked up properly.
7. Provide a cluster IP address to the respective network card.
8. Wizard should automatically detect all the unmasked LUNs on the hosts and it will give you options to format the drives as NTFS or leave it unformatted.
9. You can also enable Cluster Shared Volume from here itself.
10. Wizard will automatically configure the volume with lowest capacity as Witness disk.
11. Now you can configure Virtual Network on all the hosts in a cluster from this wizard itself, In order to do that you need to configure Logical Network on the physical network card.
12. This way you can ensure that all the hosts has an identical Virtual Network to support HA VMs
13. Now on the summary page, click on the FINISH button and your cluster is on its way.
During the cluster creation process, VMM does the following:
14. Enabling Cluster Shared Volumes
Now your Hyper V cluster is deployed and you are ready to deploy HA VMs on it.
You can also destroy the cluster using VMM console.
If you choose to destroy cluster using VMM 2012, you need to go to your Active Directory and delete the Cluster object manually.
That’s pretty much for today. In my next post, we’ll talk about update management and how VMM 2012 helps patching clustered nodes in an orchestrated manner.
