SCVMM DB Backup and cleaning with PowerShell

June 6th, 2013 No comments

I have been working on some Virtual Machine Manager deployment and configuring at a customer and after some configuration and misstakes a backup would have been nice. There is a PowerShell cmdlet in the VMM and what it does is to create a DB dump on a path that you specify. Remembering to do this every day that you work with the environment so you can recover is not always so easy and it is often that just after you make a misstake or the system does it for you, the need for backup arrises.

So setting it up with a scheduled job in PowerShell is the way to go, and the script I have also removes the backups after 7 days.

here is the simple script that does the backup and cleaning

# Backup VMM Server
# Schedule with either PSScheduledJobs or Task manager
# Niklas Akerlund 2013-06-04
$backupPath = "C:\temp"

ipmo virtualmachinemanager
Backup-SCVMMServer -Path $backupPath

get-item -Path "$backupPath\*" | where {$_.LastWriteTime -lt (get-date).AddDays(-7) -and $_.Name -match "bak"} | Remove-Item

And here is the scheduling that is done with PS Scheduling


$cred = Get-Credential
$dailybackup = New-JobTrigger -Daily -At 10:45PM
Register-ScheduledJob -Name "VMM Backup" -FilePath C:\PowerShell\backupVMM.ps1 -Trigger $dailybackup -Credential $cred

This way you at least have a backup once a day to get you to recover, and talking of recover, if you want to recover the database for the VMM you can use the binary SCVMMRecover.exe and the parameter -Path. You can find the SCVMMRecover in the following path if the VMM is installed with default settings,  ”C:\Program Files\Microsoft System Center 2012\Virtual Machine Manager\bin”

SysCtr PDT deployment session on PSUG Sweden

May 24th, 2013 No comments

Yesterday I was at the Swedish PowerShell User Group Community Day and I had a session about the System Center and deployment with PowerShell and talked about the PowerShell Deployment Toolkit.

Here is a screendump where I have installed VMM, AC,ORCH,SM,DPM,OM and also as you can see the automatic creation of shortcuts both on the desktop and the taskbar on the server that I have configured for console. As the PDT is designed to not kill itself I had to restart the deployment after rebooting the HV03 (the reason for this was the installation of .Net 3.51 which required the reboot) which was also the server running the deployment and the last part took 9 minutes. In a youtube video you can see how the deployment takes about an hour with the whole system center suite of roles and integrations between them, quite amazing!


One thing that is wrong in the package of PDT is the size of the so when the installer.ps1 is validating the size of the files the validation fails. This mp is not wrong it is just updated. Edit the workflow.xml file and set the right size and you should be fine.

In the workflow.xml file find the line and update the size to the correct value

Screen Shot 2013-05-24 at 13.45.24

I have created a small scripted file that creates all the AD accounts in the PDT as this is not included. This also create an OU that it puts all objects in so it will be more manageable and easy to find.

# Add all Accounts nesssesary for SC Deploy with PDT
# Niklas Akerlund

# Create OU´s for groups, users and Server objects
$OU = New-ADOrganizationalUnit -Name SCPDT -PassThru
$SAccounts = "installer","vmm","or","spf","ac","om_saa","om_das","om_dra","om_dwa","sm_s","sm_w","sm_r","sm_a","sm_p"

foreach ($Account in $SAccounts){
    #Account creation  
    New-ADUser -Name $Account -SamAccountName $Account -AccountPassword (convertto-securestring -string "LUMA15gate" -asplaintext -force) -PasswordNeverExpires $true -Enabled $true -path $OU
    get-adgroup "domain admins" | Add-ADGroupMember -Members (Get-ADUser $Account)

# rest of admin groups and stuff
New-ADGroup -Name SPFAdmins -path $OU -GroupScope Global -GroupCategory Security
New-ADGroup -Name SM_PDT -path $OU -GroupScope Global -GroupCategory Security
New-ADGroup -Name DW_PDT -path $OU -GroupScope Global -GroupCategory Security
New-ADGroup -Name SMAdmins -path $OU -GroupScope Global -GroupCategory Security
New-ADGroup -Name SQLAdmins -path $OU -GroupScope Global -GroupCategory Security
Get-ADGroup "SQLAdmins" | Add-ADGroupMember -Members (Get-ADgroup "domain Admins")

Upgrading to WMF 3.0 on Win 2008 R2 SP1 Hyper-V Core

April 26th, 2013 No comments

If you still have some Windows 2008 R2 SP1 Core Hyper-V hosts running and thinking of upgrading to WMF 3.0 there has been some problems with the VMM 2012.

I have a Win 2008 R2 Core SP1 Hyper-V  in my VMM 2012 SP1 UR2 and wanted to test if this was still an issue. The main reason for upgrading to the WMF 3.0 is the rebuild of the vmm refresh that is described in this blog post.

First I just tried to run the install file for WMF 3.0 and got the following dialog, and after reading a bit more realizing that it was because I need the .Net 4 as a prerequisite.


I installed the .Net 4 and there are some things that need to be configured on the Core server before and that is explained on the download page for .Net for Win 2008 R2 SP1 Core

After that It worked to install,


And after rebooting the host I looked in VMM and also tried some refresh and start/stop on VM´s and setting the host in maintenance mode, everything worked without any issues :-)

Manage your Clouds with PowerShell ppt and demofiles

April 4th, 2013 No comments

Today I was presenting on the Technet Sweden Live meeting:System Center Sp1 Springtime series and my session was about:


The presentation can be downloaded on the following link -> SC2012SP1VarenPSClouds and I have also added it to slideshare

I also promised that the powershell files I have created for the demonstrations would be downloadable and here they are, I have made one file for each of the cloud management parts

You can also read some of my other posts about App controller and how to add clouds to it, also the post about how to extend your VMM console with custom properties and also how to download and update help in SCVMM.

I will try to get some time to make some demo movies and publish them in a near future :-)

Not able to set HA on a running VM with SC VMM 2012 SP1

April 3rd, 2013 No comments

I have described before in blog posts about how to add a running VM to a Hyper-V failover cluster with the PowerShell cmdlets without moving it or turning it off, asuming it already was on a highly available storage such as a CVFS volume or smb 3.0 file share

In my exploration of the virtual machine manager PowerShell module I wanted to test and see if this was also possible in there but I do not succeed, or more correctly maybe should be noted that the SCVMM team has not implemented that for this release :-( what has been implemented is the possibility to make a VM highly available when moving between datastores on a cluster node or from a single hyper-v host to a cluster node. As there is some copying of data it will also take longer time than the below command.

In Hyper-V with failover cluster PowerShell module I can add a VM to the cluster with the following cmdlets without stopping the VM.


Hyper-V\Get-VM vmtest -ComputerName HV02 | Add-VMToCluster -Cluster HVCL30

As you see, the reason why I have added the Hyper-V to the cmdlet is that because in the VMM PowerShell cmdlet there is an alias that is called Get-VM and refers to the Get-SCVirtualMachine and that conflicts with the Hyper-V PowerShell module´s Get-VM and I have imported both modules in the same console. I have also imported the failover cluster module in the same console.

If I try to use the Set-SCVirtualmachine vmtest -HighlyAvailable $true I get the following error.

sethighavailvmmIn the VMM Console this option is also greyed out and cannot be set.


Here is the command to move the VM from one datastore to another and in the same time making it highly available,


I have made a blog post about the issue with Move-SCVirtualMachine not updating the cluster resource and this can be a way to handle this but in my opinion a far more complicated way as you have to move the VM to a new datastore and removing the high availability and then moving it again to another datastore and making it high available again, with a large virtual machine this can take some considerable time when it otherwise just is to run the cluster cmdlet.

Adding Clouds to SC App Controller 2012 SP1 with PowerShell

March 28th, 2013 No comments

Last post I did was about how to get the connection to an remote SC App Controller Server with the SCAC PowerShell module.

Now I will show you how to add your Private and Public Cloud to your App Controller with the PowerShell cmdlets.

First off I will add my SC VMM server, and as you can see I first connect to the App Controller and then add the VMM server.


I do not know if it is my silverlight that has some issues or, but the web console did not reflect the addition of the VMM Server until I logged of and then on the App Controller portal


PS C:\> Add-SCACCloudSystem -VMM -Name VMM2012 -ServerName vmm2012.lumademo.local -Port 8100

Then I will add my Azure account and that is done by adding an subscription, here you will need the certificate with the private key for the management certificate that you uploaded to your Azure subscription. And yes I have cluttered out the password and subscription Id in the screendump so it is not your monitor that broke ;-)



PS C:\> Add-SCACAzureSubscription -Name vNiklas -Id your-azure-subscription-id -ManagementCertificatePath C:\temp\certazure.pfx -ManagementCertificatePassword (ConvertTo-SecureString -AsPlainText "YourCertPassword" -Force)

Pretty easy and now I have two clouds in my App Controller, I can also add a SPF cloud connection from a third party vendor to get a truly hybrid cloud, that I have not set up yet though so it will have to be in another post.

Using SC App Controller 2012 SP1 PowerShell module remote

March 26th, 2013 3 comments

Today I have been exploring the System Center App Controller 2012 SP1 and the PowerShell module that it has.

There is not so many cmdlets in this but maybe it is enough… will find out soon :-)

Screen Shot 2013-03-26 at 20.55.51

One cmdlet that is necessary is the Get-SCACServer if you are running the powershell module remote. Here comes the small problem when like me not using a certificate from a trusted CA like the AD CS or bought by a small amount of $$$ from verisign or other vendor of certs. As you can see on the next screendump I get a small error that the cmdlet does not like the certificate, well as there is no -force parameter on the cmdlet I went for another aproach and I added the self-signed cerificate from the App Controller server that was used in the IIS to the trusted root certificate authorities certificate store in the cert manager on the Management machine where I wanted to run the appcontroller PowerShell module. And now the cmdlet did not complain and I could get the App Controller server :-)

Screen Shot 2013-03-26 at 21.43.22

Here you can see where I added the cerificate,

Screen Shot 2013-03-26 at 21.59.48

When using the App Controller PowerShell module locally on the same server as the App Controller Server resides this trust of the cert is already taken care of :-)

A good post on how to create your own certificates for example using in management of your Azure or your IIS SSL you can find here on this link.

Downloading help for SC VMM 2012 SP1 PowerShell module

March 25th, 2013 No comments

Today I wanted to use the help in SC Virtual Machine Manager PowerShell console and found that I had to download the updated help before I could see the whole, and of course I tried to do that but encountered the little error that follows in the screendump as you see,

Screen Shot 2013-03-25 at 10.35.55

I had used the PowerShell shortcut in the VMM Console, and was using my own login account, It is part of administrators/domain admins but still had not proper rights on the VMM server.

Screen Shot 2013-03-25 at 19.59.53

I opened a new PowerShell console by right click on the shortcut on the taskbar and chose Run-As Administrator and typed:

Import-Module virtualmachinemanager
Update-Help -Module virtualmachinemanager

And now I can see the full help :-)
