]]> SCVMM Cmdlets allow SCVMM admin/users to do everything they can do in SCVMM AdminConsole in windows PowerShell command line. In SCVMM 2008 R2, you can run following command in PowerShell to run SCVMM cmdlets.

Add-PSSnapin Microsoft.SystemCenter.VirtualMachineManager

But this does not work in SCVMM 2012 as SCVMM 2012 uses PowerShell module. For SCVMM 2012 now you need run following in PowerShell instead

Import-Module "C:\Program Files\Microsoft System Center 2012\Virtual Machine Manager\bin\psModules\virtualmachinemanager\virtualmachinemanager"

(This assumes that you have SCVMM 2012 installed on the default location C:\Program Files\Microsoft System Center 2012 )

The PowerShell cmdlets in SCVMM 2012 change a lot in SCVMM 2012, you can get a list of all SCVMM 2012 cmdlets by typing the following at the PowerShell command shell prompt

Get-Command -Module virtualmachinemanager -Type cmdlet

And you can run Get-Help on any of the cmdlets to get the syntax for that cmdlet.

Get-Help <cmdlet name> -detailed

Update: Microsoft has published the SCVMM 2012 cmdlets help to TechNet, check it out http://technet.microsoft.com/en-us/library/hh801697.aspx

]]> You might get following error when you load a snap-in that is written by DotNet 4.0.

This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded.

This is because by default, PowerShell uses DotNet version 2.0 CLR. To use powershell load DotNet 4.0 assemblies, the following settings need to be added in PowerShell.exe.config under C:\Windows\SysWOW64\WindowsPowerShell\v1.0.

<configuration>
    <startup useLegacyV2RuntimeActivationPolicy="true">
        <supportedRuntime version="v4.0.30319"/>
        <supportedRuntime version="v2.0.50727"/>
    </startup>
</configuration>

Note:

  1. Above applies to 64bit windows server 2008 r2. On a 32 bit machine, PowerShell.exe.config can be found at C:\windows\System32\WindowsPowerShell\v1.0
  2. Create PowerShell.exe.config if this file is not found.

]]> PowerShell scripts are text files with ".ps1" extensions that contain PowerShell commands. Starting with Windows Server 2008, PowerShell is built into the OS. For earlier OS versions, you will need to download PowerShell at Microsoft PowerShell Site and install it.

To run ps1 scripts, you first need to enable scripts by running:

Set-ExecutionPolicy RemoteSigned

Otherwise, you will get this error message:

File <script> cannot be loaded because the execution of scripts is disabled on this system. Please see "get-help about_signing" for more details.

The most common way to run PowerShell scripts is from Windows PowerShell command prompt. You must specify a path to the script to run it. If the script is in your current folder, then you can run it with:

.\script.ps1

If the script is in another folder, you need specify the full path:

c:\scripts\script.ps1


    How to enable PowerShell scripts

    1. Open a PowerShell command prompt and type Set-ExecutionPolicy RemoteSigned

      clip_image001

    2. You will be asked if you are sure

      clip_image002

    3. Select ‘Y’ and hit <enter>

      clip_image003

    You are now setup to run scripts on your machine. Note that if you use a 64 bit machine then you need to set the policy for both x86 and x64 PowerShell. If at any time you want to switch back to not allowing scripts, run “Set-ExecutionPolicy Restricted”.

    ]]>     To install PowerShell on Windows Server 2008 R2 or Hyper-V Server 2008 R2, following features needs to be installed.

    1. NetFx2-ServerCore
    2. NetFx3-ServerCore
    3. MicrosoftWindowsPowerShell

    Because Powershell is built on DotNet framework, DotNet 2.0 and 3.5  has to be installed prior to PowerShell installation.

    To install PowerShell from command line, run following from elevated command prompt

    DISM.exe /online /enable-feature /featurename:NetFx2-ServerCore DISM.exe /online /enable-feature /featurename:NetFx3-ServerCore DISM.exe /online /enable-feature /featurename:MicrosoftWindowsPowerShell

    Or run following command if it’s an 64bit machine

    DISM.exe /online /enable-feature /featurename:NetFx2-ServerCore-WOW64 
    DISM.exe /online /enable-feature /featurename:NetFx3-ServerCore-WOW64 
    DISM.exe /online /enable-feature /featurename:MicrosoftWindowsPowerShell-WOW64
