You can grant a user role to a virtual machine with following command:

1
2
3
$UserRole = Get-SCUserRole -Name "Test User Role"
$VM | Set-SCVirtualMachine -Owner $UserRole.Members[0].Name -UserRole $UserRole
Grant-SCResource -Resource $VM -UserName $UserRole.Members[0].Name -UserRoleID @($UserRole.ID.Guid)

After that you will be able to reach it from System Center App Controller.

You can use following script to get VM CPU Counts on SCVMM 2012 R2:

1
2
3
4
5
6
7
8
9
PS C:\Users\yusufozt\Desktop> $Results = Get-VM | Measure-Object -Property CPUCount -Sum
PS C:\Users\yusufozt\Desktop> $Results
 
Count    : 108
Average  :
Sum      : 292
Maximum  :
Minimum  :
Property : CPUCount

You can get total count by using $Results.Sum value.

You can get VM list in a VMHostCluster with following command:

1
((Get-SCVMHOST -VMHostCluster $Cluster).Name | foreach { Get-VM -VMHost $_ }).Name

That will output all virtual machine names in that cluster.

You can use this script to move your VMs into another Cloud (Cloud Migration) and Cluster on SCVMM 2012 R2.
This script only works on SCVMM 2012 R2 due to vHBA control.
You can remove vHBA control to make it work on SCVMM 2012 SP1.

You can query network adapter information via WMI. Just add your all hosts into Servers.txt and use following script:

1

10
11
12

$Servers = Get-Content Servers.txt
foreach ($Server in $Servers)
{
	$ErrorActionPreference = "silentlycontinue"
	$Ping = New-Object System.Net.Networkinformation.ping
	$Status = $Null
	$Status = ($Ping.Send("$Server", 1)).Status
	if ($Status -eq "Success")
	{
		ForEach ($Adapter in (Get-WmiObject Win32_NetworkAdapter -ComputerName $Server))
		{  
			$Config = Get-WmiObject Win32_NetworkAdapterConfiguration -Filter "Index = '$($Adapter.Index)'" -ComputerName $Server
			if ($Config.IPAddress)
			{
				$Output = $Server + ";" + $Adapter.Name + ";" + $Config.IPAddress[0] + ";" + $Config.MacAddress
				Write-Host $Output
			}
		}
	}
}

After that you will see all network adapters and ip configurations.

function Get-WinHBAInfo

	param ($ComputerName="localhost")
 
	# Get HBA Information
	$Port = Get-WmiObject -ComputerName $ComputerName -Class MSFC_FibrePortHBAAttributes -Namespace "root\WMI"
	$HBAs = Get-WmiObject -ComputerName $ComputerName -Class MSFC_FCAdapterHBAAttributes  -Namespace "root\WMI"
 
	$HBAProperties = $HBAs | Get-Member -MemberType Property, AliasProperty | Select -ExpandProperty name | ? {$_ -notlike "__*"}
	$HBAs = $HBAs | Select $HBAProperties
	$HBAs | %{ $_.NodeWWN = ((($_.NodeWWN) | % {"{0:x2}" -f $_}) -join ":").ToUpper() }
 
	ForEach($HBA in $HBAs) {
 
		# Get Port WWN
		$PortWWN = (($Port |? { $_.instancename -eq $HBA.instancename }).attributes).PortWWN
		$PortWWN = (($PortWWN | % {"{0:x2}" -f $_}) -join ":").ToUpper()
		Add-Member -MemberType NoteProperty -InputObject $HBA -Name PortWWN -Value $PortWWN
 
		# Output
		$HBA
	}
}

Usage:

Get-WinHBAInfo -ComputerName Server01

After that you will see HBA and Port WWN information.

You should run this script on your Windows Server 2012/R2 DNS server with elevated privileges.
