Windows Server Add VHD disk or boot from VHD disk #WS2012 #VHD


Did You know that you can add a VHD disk to your windows 2008 R2 Server and /or boot from it ?

You can easy edit the VHD and reuse it in hyper-v.

So go to disk manager and right click on disk management image

You can create a new VHD. image If you use dynamic make sure you have the disk space that u needed.

I use a fixed disk with windows 7 on it. that I use in hyper-v as golden Image for my desktops.

image fill in the VHD location. image  You can make it read only if you need software install that is on a VHD, I have a VHD with all the ISO files on it that I can mount on every server if I need to install extra software or tools.

But now I use the Windows 7 VHD image now that I mounted the disk I can use it.

I need a WallPaper on the windows 7 image image

image now I can do a offline or detach vhd , If I don;t I get this error in hyper-v

image even if the disk is offline image

image You can also delete the VHD 😉

image image image

or You can boot from the VHD it is just like in windows 7   mount it and use bcdedit to change the boot string.

below are samples.

bcdedit /set {GUID} device file=[c:]\vhd\win7.vhd
bcdedit /set {GUID} osdevice file=[c:]\vhd\win7.vhd


Here are some articles and video about booting from VHD.

SQL Server Failover Cluster Installation

The installation of a SQL cluster is easy There is a Menu Item Create new Failover Cluster. #ws2012 #SQLsp1 #sql2012 #cluster #fail #howto

Well I don’t use this option Winking smile Why not to easy eh yes but more important is something fails like wrong IP etc the SQL install is lost , you need to deinstall the whole SQL mesh, I like the advanced version and trust me it will be easy.

OR you can loop at the technet site to see how and when:

SQL Server Failover Cluster Installation

SQL Server 2012

To install a SQL Server failover cluster, you must create and configure a failover cluster instance by running SQL Server Setup.

So how Do we start this installation. Well you can see my blog post :

This blog post covers all the screen shots but this post is more a part…

For Creating a ISCSI target on a cluster you get a high available iscsi target.

Sure you can run this on a single server (VM ) and move this between the hyper-v nodes.

for doing this in a cluster you need to do the following steps.

Add cluster Resource ISCSI target , fill in the netbios name that you want for the iscsi target



give the target a disk that will hold the VHD files



Now that the cluster resource is created the iscsi target is ready to use.

There is no option in the cluster to start the iscsi target you have to start this in the server manager


As here you can create a new VHD file and use this for targeting , I have no groups so this needs to be created first. I use a small disk just for testing.

Now that Windows 2012 is here and you want to test if the OS is as good as you want and see if the application is still running on windows 2012.

In this case We build a NLB website easy with just the basic steps any one can do this.

First we add the roles and features to the servers that we are going to use for the NLB.

Select the Features “ Network Load Balancing ” only this you need for NLB




After this I look at my NIC’s most important that you use two nic’s in a VM this is easy in a physical box now days there are at least 2 nic’s in the server. use them.

I gave the Nic’s an IP that is not in the same subnet as the production lan, and also you can use a different VLAN for the NLB…

Now that windows 2012 is in beta we can talk almost about anything and it is time to create my demo SQL 2012 machine. In this case I uses the Windows server 8 cluster from the other blog item to create a SQL 2012 cluster with 3 instances. All of the instances are created on different ways , Instance 3 is a ZTI Winking smile  #WS2012 #TEE #TEE13 #MVP13

For starters build a 2 node cluster or more nodes if you want and use the SQL 2012 Media. I use the Enterprise version.

Remember that I create the Server Group image and my cluster image I already added the disk to my cluster mounted the SQL 2012 ISO file to the node. Ready for the Setup.

again I use a lot of pictures in this blog and I do almost everything twice just to show you how you can configure your cluster.
