SCVMM 2012 – Creating a Hyper-V Cluster
This culminating blog in a series on SCVMM 2012 shows how to create a Hyper-V R2 cluster in System Center Virtual Machine Manager 2012. With the arrival of Windows Server 2008 and 2008 R2, cluster creation has almost become a trivial job, largely because of the excellent Cluster Validation Wizard. The previous blogs showed us what preparations to make before we could perform a successful bare metal deployment. One moment you have 16 unconfigured blades, the other you have 16 fully installed Windows Server 2008 R2 hosts including the Hyper-V role. All that is left is to build a cluster from them … the easy way!
Because I didn’t have 16 available blades I had to settle for only two. But you’ll get the idea despite of this.
In Fabric | Servers we see three hosts in a host group called Research. The cluster will be built from the bottom two servers hv11 and hv12.
Let’s first look at the properties of one of those physical servers.
The hardware properties of the physical server shows the BMC settings as used during the bare metal deployment.
Under Network Adapters one or more mappings can be made with logical networks. A distinction can be made between Available for placement (of guests) or Used by management.
Creating the cluster
The actual cluster creation is started by pushing Create | Hyper-V Cluster which starts the Create Cluster Wizard
Enter the cluster name and credentials for creating the cluster. Oddly enough we don’t get to select a Run As Account. Instead we have to supply the username and password manually.
In the next step we select a target host group and add up to 16 hosts that will be part of the new Hyper-V cluster.
The cluster requires a unique IP address. Both IP v4 and v6 can be entered.
Next a choice is given of shared disks that will be part of the cluster. The wizard automatically selects the smallest disk for witness disk (if the number of nodes dictates this kind of quorum).
The Create Cluster Wizard can also create external virtual networks. Having named the different physical networks and creating the logical networks in SCVMM 2012 beforehand makes this job a little easier.
The final step shows the Summary of all previous choices.
Clicking the Finish button sets the cluster creation in motion.
What is interesting if you study the detailed steps of the cluster creation job is that several tasks are performed in parallel (step 1.2.1)
Of course Cluster Validation is also part of the procedure (1.5) and passing this will make the cluster fully supportable by Microsoft, regardless of the underlying hardware.
Assuming you will be using SP1 for Hyper-V R2 clusters, please note that there will be a hotfix for being able to complete cluster validation successfully with 3 or more cluster nodes. I will update this text if I get the exact KB article number.
The cluster is now fully operational
… and visible in SCVMM 201
This concludes a series of SCVMM 2012 blogs that show the radically improved new Virtual Machine Manager that is expected to RTM in the second half of 2011. I’m sure we will have a lot of fun with this product in the years ahead!

You may or may not have noticed it, but the daily stream of updates around Windows Azure Pack is becoming more and more amazing. The WAP Wiki initiative I took with Marc van Eijk several weeks ago, makes us very aware of all the blogs and articles that are published around Windows Azure Pack, Service…

A hotfix has been released today for Windows Server 2012 Hyper-V servers which are unable to access LUNs over a Synthetic Fibre Channel after a VM is live migrated to another host in the cluster. This problem can occur if the following conditions are met: You have two Windows Server 2012-based computers that have the…

In previous blogs I wrote about 5nine Security Manager for Hyper-V: http://www.hyper-v.nu/archives/pnoorderijk/2013/02/5nine-security-manager-for-windows-server-2012-hyper-vpart-1/ http://www.hyper-v.nu/archives/pnoorderijk/2013/03/5nine-security-manager-for-windows-server-2012-hyper-vpart-2/ 5nine Security for Hyper-V delivers a multi-layered Agentless Security solution including anti-virus, virtual firewall and intrusion detection (IDS). Today 5nine announced full support for Windows Server 2012 R2, Windows 8.1 release previews, as well as Hyper-V Server 2012 R2. “As Microsoft continues…

Not very often do I remember a Windows Update KB article off the top of my head, but this time I have talked and written about KB2855336 so often that it was probably written into my short term read-cache.. If you have been careful and missed the first version of this update because you rather…

In my last blog I sent out a red alert on a killer Windows Update that had not been sufficiently tested. The net result was a full crash of a two-node System Center fabric management cluster. The fabric was still in the making and backups were only provisionally taken in the form of Virtual Machine…

[Update July 13, 2013 - I was able to deploy the newly issued KB2855336 to all of my physical and guest cluster nodes. There have been no issues so far. The same KB will also show up in most of your VMs as it is a collection of 21 updates touching all kinds of bugs…

Last week at TechEd I attend a session about migrating from VMware tot Hyper-V. Impressive session, which I must attend because a lot of my customers want to migrate from VMware tot Hyper-V because of the huge improvements in Windows Server 2012 Hyper-V and Windows Server 2012 R2 Hyper-V. What tools do we have to…

Today I received word from Microsoft that I am re-awarded as a Microsoft Most Valuable Professional for Virtual Machine. When I received my first award for Cluster back in 2009, I could not begin to understand its consequences and how much such an award would mean in terms of recognition, access to knowledge, direct contact…

Update June 26, 2013: Cristian Edwards notified me that he has updated the script to now support using a cluster name. That will save you some typing if you cluster counts 64 nodes. See end of blog Update July 1, 2013: Great to see that Niklas Akerlund and Trond Hindenes made great extensions on the…
