Generating reports of VMs with Dynamic Disk

Posted in Virtual Machine Manager, Windows Powershell, Windows Server | No Comment | 3,580 views | 22/08/2013 10:12

This is pretty cool and detailed report for VMs with Dynamic Disk. It requires SCVMM 2012 to get details but it’s possible to change it to use Hyper-V PowerShell Cmdlet.

$VMs = Get-VM
foreach ($VM in $VMs)
{
	$Disks = Get-VM $VM | Get-SCVirtualHardDisk
	foreach ($Disk in $Disks)
	{
		if ($Disk.VHDType -ne "FixedSize")
		{
			$DiskLocation = $Disk.Location
			$CSVVolume = ($Disk.Location.Split("\"))[2]
			$DiskName = ($Disk.Location.Split("\"))[-1]
			$DiskSize = ([math]::round(($Disk.Size/1GB), 0))
			$DiskMSize = ([math]::round(($Disk.MaximumSize/1GB), 0))
			$DiskHost = $Disk.VMHost
			$CSVFreeSpace = ([math]::round(((Get-SCStorageVolume | where VMHost -eq $DiskHost | Where Name -like "*$CSVVolume*").FreeSpace/1GB), 0))
			$CSVCapacity = ([math]::round(((Get-SCStorageVolume | where VMHost -eq $DiskHost | Where Name -like "*$CSVVolume*").Capacity/1GB), 0))
			$Value = $VM.Name + ";" + $DiskName + ";" + $CSVVolume + ";" + $CSVFreeSpace + ";" + $CSVCapacity + ";" + $DiskMSize + ";" + $DiskSize + ";" + $DiskHost
			Add-Content -Path DiskUsage.txt -Value $Value
		}
	}
}

It also shows CSV volume name, capacity and free space information.

Getting unused directories in Hyper-V ClusterStorage Volumes via PowerShell

Posted in Virtual Machine Manager, Windows Powershell | No Comment | 2,667 views | 15/08/2013 10:25

You may export and move a VM to another host or volume, or maybe you may delete a VM but configuration and VHD files may still exist on old location. In that case, you can use this script to find that old VM directories.

# Get Cluster Nodes
$ClusterNodes = "Cluster01Node01","Cluster02Node02"
 
foreach ($ClusterNode in $ClusterNodes)
{
	$Volumes = Get-ChildItem -Directory -Path \\$ClusterNode\C$\ClusterStorage\
 
	foreach ($Volume in $Volumes)
	{
		$ConfigFolders = Get-ChildItem -Directory -Path \\$ClusterNode\C$\ClusterStorage\$Volume
 
		foreach ($ConfigFolder in $ConfigFolders)
		{
			$Result = "0";
			$VMName = "";
 
			$ClusterNodes = Get-Cluster $ClusterNode | Get-ClusterNode
 
			foreach ($ClusterNode in $ClusterNodes)
			{				
				$VMs = Get-VM -ComputerName $ClusterNode
 
				foreach ($VM in $VMs)
				{
					$FullName = $ConfigFolder.FullName
					$FullPath = "C:\" + $FullName.Split("\")[4] + "\" + $FullName.Split("\")[5] + "\" + $FullName.Split("\")[6]
					if ($FullPath -like $VM.ConfigurationLocation)
					{
						$Result = 1;
					}
 
					$VirtualDisks = Get-VM -ComputerName $ClusterNode -Name $VM.Name | Get-VMHardDiskDrive
 
					foreach ($VirtualDisk in $VirtualDisks)
					{						
						if ($VirtualDisk.Path -like "$FullPath*")
						{
							$Result = 1;
						}
					}
				}
			}
 
			if ($Result -ne "1")
			{
				Write-Warning $ConfigFolder.FullName
			}
		}
	}
}

$ClusterNodes should contain different Cluster’s only one nodes. Using with that node name, we can query other nodes too.

Set User Role Quota for each Cloud Profile in SCVMM 2012 SP1 – Method 2

Posted in Virtual Machine Manager, Windows Powershell | No Comment | 1,915 views | 12/08/2013 14:17

You can set User Role Quota for each Cloud Profile in SCVMM 2012 SP1.

$UserRoles = "BackOffice","CallCenter"
foreach ($UserRole in $UserRoles)
{
	$UserRole = Get-SCUserRole $UserRole
	$Clouds = "DMZ Cloud","Prod Cloud","Test Cloud"
	foreach ($Cloud in $Clouds)
	{
	   $MyCloud = Get-SCCloud $Cloud
	   $CloudUsage = Get-SCCloudUsage -Cloud $MyCloud -UserRole $UserRole
	   $CPUCount = $CloudUsage.CPUUsageCount
	   $Memory = $CloudUsage.MemoryUsageMB
	   $VMCount = $CloudUsage.VMUsageCount
	   [int]$NewCPUCount = [int]$CPUCount + 40;
	   [int]$NewMemory = [int]$Memory + 81920;
	   [int]$NewVMCount = [int]$VMCount + 10;
	   Get-SCUserRoleQuota -UserRole $UserRole -Cloud $MyCloud | Set-SCUserRoleQuota -CPUCount $NewCPUCount -MemoryMB $NewMemory -VMCount $NewVMCount
	}
}

That will set on all profiles on $UserRoles array.

You can set User Role Quota for each Cloud Profile in SCVMM 2012 SP1.

$UserRoles = "BackOffice","CallCenter","ExchangeTeam"
foreach ($UserRole in $UserRoles)
{
	$UserRole = Get-SCUserRole $UserRole
	$Clouds = "DMZ Cloud","Prod Cloud","Test Cloud"
	foreach ($Cloud in $Clouds)
	{
		$MyCloud = Get-SCCloud $Cloud
		$CPUCount = (Get-VM -Cloud $MyCloud | Where UserRole -like "$UserRole" | Measure-Object -Property CPUCount -Sum).Sum
		$Memory = (Get-VM -Cloud $MyCloud | Where UserRole -like "$UserRole" | Measure-Object -Property Memory -Sum).Sum
		$VMCount = (Get-VM -Cloud $MyCloud | Where UserRole -like "$UserRole").Count
		[int]$NewCPUCount = [int]$CPUCount + 40;
		[int]$NewMemory = [int]$Memory + 81920;
		[int]$NewVMCount = [int]$VMCount + 10;
		Get-SCUserRoleQuota -UserRole $UserRole -Cloud $MyCloud | Set-SCUserRoleQuota -CPUCount $NewCPUCount -MemoryMB $NewMemory -VMCount $NewVMCount
	}
}

That will set on all profiles on $UserRoles array.

Changing UserRole of some Virtual Machines on SCVMM 2012 SP1

Posted in Virtual Machine Manager, Windows Powershell, Windows Server | No Comment | 2,443 views | 26/07/2013 12:06

You can change UserRoles of virtual machines on SCVMM 2012 SP1 with following command:

$VMs = Get-VM | Where Name -like "*CALL*" | Where UserRole -eq $Null
foreach ($VM in $VMs)
{
	$UserRole = Get-SCUserRole "MyUserRole"
	$VM | Set-VM -Owner "DOMAIN\Owner" -UserRole $UserRole
}

That will only change “null” user roles. If you want to change existing user roles:

$VMs = Get-VM | Where Name -like "*CALL*" | Where UserRole -like "OldUserRole"
foreach ($VM in $VMs)
{
	$UserRole = Get-SCUserRole "NewUserRole"
	$VM | Set-VM -Owner "DOMAIN\Owner" -UserRole $UserRole
}

It will only looks for VMs like “CALL”. You can leave it blank for all virtual machines.

Getting total CPU and Memory usage of UserRole in SCVMM 2012 SP1

Posted in Virtual Machine Manager, Windows Powershell | No Comment | 2,232 views | 26/07/2013 11:59

You can get total CPU and memory usage of a user role with following command:

1	(Get-VM \| Where UserRole -like "MyUserRole" \| Measure-Object -Property CPUCount,Memory -Sum)

That will give you total count of cpu and memory.

Getting Hyper-V Failover Clusters List via PowerShell

Posted in Virtual Machine Manager, Windows Powershell, Windows Server | 1 Comment | 3,571 views | 16/07/2013 09:23

You can get Cluster names from your Hyper-V host list with following PowerShell script:

# Prepare Cluster Array
$ClusterArray = New-Object System.Collections.ArrayList
$Servers = Get-Content -Path C:\Servers.txt
foreach ($Server in $Servers)
{
	$VMHost = Get-VMHost -ComputerName $Server
	$HyperVFQDN = $VMHost.FullyQualifiedDomainName
	if ($VMHost)
	{
		$ClusterName = (@(Get-Cluster $Server | Get-ClusterGroup | where GroupType -eq "VirtualMachine") | Select-Object -First 1).Cluster.Name
		if ($ClusterName)
		{
			$TestCluster = $ClusterArray.Contains("$ClusterName")
 
			if ($TestCluster -ne $True)
			{
				# Update Cluster Array
				$ClusterArray.Add("$ClusterName") | Out-Null
			}
 
			Write-Host $ClusterName
		}
	}
}

After that you can use your Cluster names to get CSV reports.
