Installing a Highly Available (Cluster) System Center Virtual Machine Manager 2012
So you might have seen my previous in creating a highly available SQL Server series and now I would like go through steps on how to create a highly available SCVMM 2012. Now, ideally if you’re gonna make your SCVMM highly available it only makes perfect sense to also have you SQL database where it is sitting on is highly available as well. If you’ve missed that head over here to get it. Alright, let’s go!
Now if you’ve already gone through to create your SQL cluster already, creating a highly available SCVMM is a lot easier and you’ll soon realize why. First, is to get both your nodes installed with the Failover Clustering feature. I’m sure you’ve probably done this so go to the Server Manager > Add roles and features.
and again click Next.
No roles to install, so click Next.
Here, click to select Failover Clustering and then click Add Features when the windows appears.
Click Install to proceed. Now all you gotta do is repeat this on the second SCVMM node. I’m not gonna run through that here. Basically follow these same steps on the other machine.
Once you’re done with that, open up your Failover Cluster Manager console. Right-click on it and select Create Cluster.
Click Next here.
Put both nodes into the cluster, then click Next.
Select Yes and then click Next.
Select to run all tests, then click Next.
Click Next to start.
And the progress…and then done. Click Finish.
Give your cluster a name and an IP address then click Next.
Make sure to uncheck the box for Add all eligible storage to the cluster then click Next.
It’s going…and done. Click Finish.
Next is to install your SCVMM. Select the VMM management server.
A message will appear to tell you that it detected that this computer is within a failover cluster and if you would like to make this installation of SCVMM highly available. Definitely click Yes.
If you just need it for evaluation, click Next. Otherwise enter your product key here.
Accept the EULA and click Next.
Accept the CEIP if you like then click Next.
Turn on Microsoft Update, click Next.
Accept the default location, then Next again.
There’s a warning here but that’s okay. I am still able to proceed. The minimum amount of memory to continue with the installation is 2000MB. I was short of memory on my laptop thus I had to do some reorganising :).
Here you should be putting in your SQL Cluster name so that if one of your SQL node fails it will still be contactable by VMM where the failover will be transparent and automatic.
Here you need to give your VMM cluster a name and an IP address then click Next.
Put in a domain account and password for the service account and also a location where SCVMM will be able to store the encryption keys. Active Directory is the best place to store it.
Accept the defaults then click Next.
Because it is a cluster, you will not be able to place the libraries here. Go ahead and proceed by clicking Next.
Click Install to begin the installation.
The progress…and you’re done. Click Finish. Now all you gotta to do is to repeat these steps on the second VMM node.
Running setup on the second node will give you this message that says that it has detected a VMM cluster and whether you would like to add this as an additional node to the cluster. Click Yes. The remainder of the wizard is basically the same except that many of the option has either been filled up for you or grayed out because it was filled in during the first node installation.
Now your VMM cluster is up and enjoy playing around failing over and failing back.
