Virtual machines show two datastores in the summary tab

Reading Time: < 1 minute

You have migrated your virtual machines to new storage but find that the summary tab of the virtual machines shows two datastores within the vSphere Web Client and vSphere Client. You have checked the datastore and no data resides on the LUN.

Here are a couple of things you want to check,

1) The most obvious is to check whether there are ISO’s mounted to your servers

2) vSwap file. Does a vSwap file exist on the data store? browse the datastore and check if any vSwap files exist. If yes, a VMotion of the Virtual Machine migrates the vswap to the new location. If you’re moving VM’s to new storage, don’t forget to check your vSwap configuration, especially if you originally configured the vSwap location to reside on a different LUN. Ensure the vSwap file location has been reconfigured to point to new storage.

3) Check if any VMWare snapshots exist. If a VMWare snapshot was taken whilst an ISO was attached to the VM, this could be the issue. Remove the snapshot


How to install AZ Module within PowerShell

Reading Time: < 1 minute

1) Firstly download and install the latest stable version of PowerShell to your device. You can download the latest version from:

https://github.com/powershell/powershell#get-powershell

To check the version of PowerShell you currently have installed, launch PowerShell, run the command below:

Get-Host | Select-Object Version

2) Now that you have the latest version of PowerShell installed, you will need to install the AZ module if not already installed. The command below will allow you to check if you already have the AZ Module installed including the version number.

Get-Module -Name Az -ListAvailable

3) If you already have the AZ module installed, the version will appear. If no version is installed, no results will appear after running the above command. You may find that you have more the one version installed.

To install the latest version, type the command below:

Install-Module -Name Az -AllowClobber

Please note, if you already have older versions of the Az Module installed, you may wish to add -force to the end of the command so that the module installs side by side with your existing versions. Such as:

Install-Module -Name Az -AllowClobber -force

Installing the module will take about a minute. Run the command below again to confirm the module has installed

Get-Module -Name Az -ListAvailable

If you have multiple versions of the AZ Module installed, the latest version will be used by default, unless you specify for an older version to be used.

Upgrade Windows Server 2012 to Server 2019

Reading Time: 3 minutes

Microsoft recommend upgrading your server OS to the latest version, but we all know that this is not always possible. Your business may be running third party applications that have not yet been tested or even compatible with later Windows Server Operating Systems.

Always check whether the applications running on your current Operating System are supported, before you decide to upgrade to a higher version OS. It will save you a lot of time and disappointment.

So let’s continue on the basis that you have carried out your checks and the applications currently running on your server to be upgraded supports Server 2019.

First, as you will already be aware, ensure you have a full backup of your server, so in the event the upgrade goes horribly wrong, you have a backup to restore to.

Note: If you have Microsoft Endpoint Protection installed, you will be prompted to remove this app. This app is not compatible with server 2019

Now, that you are all set, you may be thinking, can I upgrade directly from server 2012 or server 2012 R2 to Server 2016? The answer is yes, you can and it’s a supported method. See support matrix from Microsoft below. So whether you decide to upgrade from Server 2012 to 2019 or from 2016 to 2019 a one hop in-place upgrade is support.

Available in-place upgrade paths

Ok, so we now have a full system backup, and we know that third party apps are supported with server 2016/2019.

Before we get started with the upgrade, Microsoft recommend that you collect some information from your device, for diagnostic and troubleshooting purposes. Because this information is intended for use only if your upgrade fails, you must make sure that you store the information somewhere that you can get to it off of your device.

To collect your info

  1. Open a command prompt, go to c:\Windows\system32, and then type systeminfo.exe.
  2. Copy, paste, and store the resulting system information somewhere off of your device.
  3. Type ipconfig /all into the command prompt, and then copy and paste the resulting configuration information into the same location as above.
  4. Open the Registry Editor, go to the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion hive, and then copy and paste the Windows Server BuildLabEx (version) and EditionID (edition) into the same location as above.

Upgrade Server 2012 to 2019

1) Patch your server with the latest windows updates if not already up to date
2) Locate the Windows Server 2019 Setup media, and then select setup.exe
3) Select the Windows Server version you wish to upgrade to

Screen to choose which Windows Server 2012 R2 edition to install

4) Accept the licensing terms

Screen to accept your license agreement

5) If you’re running Microsoft Endpoint Protection on your server, setup will prompt for this app to be removed as it isn’t compatible with Windows Server 2019

6) Select Keep personal files and apps, and then select Next

Screen to choose your installation type


7) After Setup analyses your server, setup will prompt you to proceed with your upgrade by clicking install

Screen showing you're ready to start the upgrade

8) Wait for the upgrade to complete

Screen showing your upgrade progress

9) To ensure the upgrade completed successfully

– Open the Registry Editor, go to the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion hive, and view the ProductName. You should see your edition of Windows Server 2019, for example Windows Server 2019 Standard. Make sure all of your applications are running and that your client connections to the applications are successful.

If you think something might have gone wrong during your upgrade, copy and zip the %SystemRoot%\Panther (usually C:\Windows\Panther) directory and contact Microsoft support.


How to build a server in Azure

Reading Time: 5 minutes

Building a server in Microsoft Azure is simple and has become easier as Microsoft have made improvements on the portal over the years.

In this example, i’ll be building a Windows 2019 Server, so lets get started

Logon to your Azure Portal, search for virtual machines and click + Add


The below interface appears, select your subscription from the drop down list. If you only have the one, it will already be selected

Next, drop down and select a resource group.

What is an Azure Resource Group?
A resource group is a container that holds related resources for an Azure solution. The resource group includes those resources that you want to manage as a group. You decide which resources belong in a resource group based on what makes the most sense for your organisation.

For the purposes of this demo, I’m going to create a new resource group

Next, lets give our virtual server a name and select a region. I have selected UK South

Next, I’m going to create this VM in a new availability set, because I will be building and adding another virtual web server and including it within the same availability set to provide for high availability. If you’re not interested in creating an availability set, you can skip these steps. But because it doesn’t cost anything to create an availability set, you may want to add the server to an availability set if you have plans of setting up redundancy in the future. You’ll obviously be charged for the second server, but the availability set is free. If you decide at this point you don’t require redundancy, but in the future change you’re mind, you will have to delete and recreate the VM to allow you to add it to a new availability set.

What is an Azure availability set?
An availability set is a logical grouping of VMs within a datacenter that allows Azure to understand how your application is built to provide for redundancy and availability. Azure makes sure that the VMs you place within an Availability Set run across multiple physical servers, compute racks, storage units, and network switches.
More info at: Azure Availability Options

Create a new availability set (I’m leave the defaults) and click OK. When you create another server, drop down and select an existing availability set. The below screenshot shows my new availability set. It’s worth looking into how fault domains and update domains function.


Next, select your Operating System. I have selected Windows Server 2019 Datacenter and a size of Standard DS1 v2 for this demo. The higher spec server the more it will cost you so ensure you select the correct server size depending on requirements

You may have noticed Azure Spot Instance. What is Azure Spot? Azure Spot offers unused Azure capacity at a discounted rate versus pay as you go prices. Workloads should be tolerant to infrastructure loss as Azure may recall capacity for pay as you go workloads. It’s recommended to use Azure Spot only if you’re testing and are happy for Microsoft to delete your VM without much notice. Never use this for production or even a test environment you require access to at all times.

Next setup your local administrator account and a strong password. For inbound public ports, I have set none. I will be accessing this server internally via RDP and don’t want to expose RDP to the outside world. If Bastion is available with your region, you could set it up so you can access your VM from within the portal. For more details on how to configure Azure Bastion, click How to Configure Bastion? If you have a requirement for public RDP to be enabled, lock down access to certain IP addresses and it’s worth setting up Azure Just In Time Access.

What is Azure Just In Time Access?
Just-in-time (JIT) virtual machine (VM) access can be used to lock down inbound traffic to your Azure VMs, reducing exposure to attacks while providing easy access to connect to VMs when needed. The just-in-time feature is available on the Standard tier of Security Center

Click next, to configure disks. Select your disk types depending on your server/application requirements

You may also have a requirement to add an additional disk, such as a data disk. Don’t worry about creating a page file disk. You’ll get a temporary disk assigned by default


So here is what my disk configuration looks like. OS and a data disk

Click next to visit networking settings

Select your virtual network, subnet, a public IP if required and basic or advanced NSG. The common NSG is basic but will obviously depend on your company requirements. You can also control the NSG at subnet level within your VNET, or even route all traffic to an external firewall, such as a Paloalto firewall. It’s worth consulting with your networks team on security requirements.


When ready click next and configure management settings as required

I have set my machine to auto shut at 7pm. It’s only a test server and doesn’t need to be powered on after 7pm. Will save me on costs while it’s powered down.


Click next. If you have any requirements to install any extensions, such as Microsoft Antimalware, you can select here. If you’re not sure just yet, don’t worry about it, as you can select extensions after the VM build. It’s worth taking a look at the available extensions though. Click Next when ready

Create tags if required. Explanation of tags below

And click review and create

You’ll receive a notification after the VM has been built
