Powershell - Add page file Disk and set the page file on a VM inSCVMM 2012

  • Article

Hi

I was looking at writing a script to add a separate disk to a VM and mount it , format it and set it as Page file on your VM .  This script will do the Maths and select the page file 2 times as your VM memory and format it as 1.95 times leaving some room for NTFS partition.   It will let you remote onto the VM using local administrator credentials and formats the drive and set it as page file drive as well .

Copy and paste the below code and I hope you will like it

 

 

$JobGroupID = [Guid]::NewGuid().ToString() 
$vmname = Read-Host " Enter the VMNAME"
$username = $vmname + "\Administrator"
$cre = Get-Credential -UserName $username -Message " Enter the local administrator"
$memory = Get-SCVirtualMachine -name $vmname | select memory | Format-Table -HideTableHeaders 
$VM = Get-SCVirtualMachine -Name $vmname 
refresh-VM -VM $vm 
Shutdown-VM -vm $VM 
$memory = @() 
$memory += Get-SCVirtualMachine -name $vmname | select memory  
$memory = [string]$memory 
$memory.getType().Fullname 
$memory = $memory.trimstart('@{Memory=') 
$memory = $memory.replace('}', '') 
[String[]]$memory = $memory 
$memory 
$memory.getType().Fullname 
$memory = [string]$memory 
$pagefilesize =   2 *"$memory"
$pagefilesize 
  
  
$memory.getType().Fullname
