How to upgrade SCVMM from 2012 R2 to 2016

Hi,

today I want to provide you a quick end dirty step by step guide how to upgrade you SCVMM from 2012 R2 to 2016.

The procedure is pretty much the same like in 2012 or 2012 R2.

Single Node:

  1. Uninstall SCVMM 2012 R2 and keep your database
  2. Install all needed requirements for SCVMM 2016 on your server which are noticed in the requirements* during the installation wizard
  3. Connect the “old” SCVMM 2012 R2 database
  4. Run all updates and your done

Cluster:

  1. Uninstall SCVMM 2012 R2 from all of your nodes and keep your database
  2. delete the cluster role of the old VMM (if you want to keep the name you need to set it new)
  3. Install all needed requirements for SCVMM 2016 on your server’s which are noticed in the requirements* during the installation wizard
  4. Create a new cluster role with the old name and IP
  5. Connect the “old” SCVMM 2012 R2 database
  6. Run all updates and your done

How to fix same SMBIOS ID on different Hosts

Today one post about things I see sometimes in the field.

Today I want to show you how to fix the issue when you get servers and clients with the same SMBIOS ID. Normally that would be an issue but as soon as you try to management them with System Center Virtual Machine Manager or Configuration Manager it will become one. Both tools use the SMBIOS ID to create a primary key in their databases to identify the system.

Currently I only know the following trick to fix the issue and that one would be extremly annoying on many clients or servers but it actually work.

First you need two tools.

1: Rufus – To create a bootable USB Stick

2: AMIDMI – With that tool you can overright the SMBIOS ID

Now create the Bootstick with Rufus and copy the AMIDMI file on the stick.

Reboot your from the stick.

Navigate to the folder with your AMIDMI file and run the command amidmi /u

Afterwards you can reboot the system and start Windows again.

 

When you are working with Virtual Machine Manager, you need to remove the host from your management consolte and add it again. After the host is discovered again, you can see the new SMBIOS ID.

I currently saw these issues with following motherboard vendors:

  1. ASRock (Client & Rack)
  2. ASUS (Client)
  3. SuperMicro (Server & ARM)
  4. Fujisu (Server)

You install Hyper-V & VMM from the green? Please do it in the right order.

Hi everybody,

today another story I see most of the days when I do Healthcheck on customer site.

One of the first things I found was a new VMM installation on top of a new Microsoft Hyper-V Cluster. The issue was, that the cluster was installed first and every thing was running on Hyper-V converged network and standard Hyper-V Switches. There was no VMM network configured or the host made compliant within VMM.

Why is that so bad? It’s bad because VMM uses it’s own kind of switches (logical switches) and needs some additional configurations to manage the hosts in the best possible way.

When I ask guy’s why they do it in that way, I normally get the answer “how should I configure the host when no VMM is in place before he install the cluster?”.

So now my answer and how you can do it in the right way.

  1. Install a Hyper-V Host as Standalone host
  2. Configure and install the VMs for VMM and SQL Server (if needed) on the standalone host
  3. Performe the ful VMM configuration
  4. Install the other Hyper-V Hosts and roll out the VMM configuration to that hosts
  5. Cluster the Hyper-V Hosts
  6. Migrate your SQL DB and VMM with shared nothing livemigration to the new Hyper-V Cluster
  7. Reconfigure the standalone Hyper-V Host with VMM and add it to the cluster
  8. Run the cluster validation again

That’s all and it will cost you the same amount of time.

Virtual Machine Converter – Cannot Convert VMware VM – Disk configuration

Today I had an issue with virtual machine converter during migration of a VM from VMware to Hyper-V. The screenshot below shows the issue.

The issue shows an configuration missmatch which stopped the convert of the VM.

The solution of the issue is pretty easy. You need to check and change the virtual machine configuration in VMware vCenter.

First you need to check the SCSI Bus logic. There you need to configure LSI Logic.

Second and more likely the reason for the issue is that one or more of your disks are configured as independed. Just uncheck the box and your fine. ūüôā

How do you get your System Center Virtual Machine Manager really highly available

Sometimes when I’m invited to visit a customer to “optimize their high available virtual machine manager”, I¬†normally see following configuration.

VMMHA01

 

When I ask why they say it is high available, they normally tell me that they can move the machine from one host to another. Normally i ask now “And what happens when you need to patch the SQL DB, VMM or Windows Server or the storage fail?”

Here comes the point where most people realize that high availability means other things than moving services from A to B.

So now let us think what we need to get our VMM Server high available.

On the VMM Site we need following parts:

  • two VMM Management Servers running in a Cluster
  • two Database Servers running in a Cluster
  • two Fileserver running in a Cluster as Library server
  • two Hyper-V Hosts for VM Placement
  • two Storages with Storage Replication

VMMHA02

 

When it comes to a very big Hyper-V and VMM Environment, I would suggest to run you Management Systems in a separated Hyper-V Cluster. That helps you to keep your VM workload running even when you need to take down your fabric cluster in maintenance mode.
