vNiklas Virtualization blog

I have made a powershell script function to update information about what VLAN and IP the VM´s have. This for the IT Admin to easily see in the VMM 2012 Console. Of course the function can be customized to populate any other information available for the VM´s, maybe you want to display create date or something else that is not in the standard properties and you do not want to use the pre-made custom# .

I am using the Get-IPAddress from Ben Wilkinson, This requires that the VMM server can resolve the IP of the VM´s from a DNS.

If I do not have an DNS or the VLAN info is not stored, i can via the parameters update the properties by -IP or -VLANid.

As you can see on this screen dump, by default i only have custom#, to add my own i have to click on “Manage Custom Properties”

Here i press “Create” and add a name and optionally a description

Then when i have created the custom properties i want i add them,

Then it looks like this,

Now the powershell function comes into play when i am going to populate these fields with information.

function Set-CustomValue{
# Function to add custom data on VMs

    param (
   [Parameter(Position=0,Mandatory=$true,HelpMessage="A virtual machine pleaze",
    ValueFromPipeline=$True)]
    $VM,
	$VLANid = "",
	$IP = ""
    )
    . .\Get-IPAddress.ps1

    $VM = Get-SCVirtualMachine $VM

  	$CustomIP = Get-SCCustomProperty -Name "IP"
    $CustomVLAN = Get-SCCustomProperty -Name "VLAN"

	if ($IP -eq ""){
		$IP = Get-IPAddress -HostName $VM.Name
    }

	if ($VLANid -eq ""){
	    $VMnics = $VM | Get-SCVirtualNetworkAdapter
	    if($VMnics.Count -ne $null){
	        foreach ($VMnic in $VMnics){
	            $VLANid = $VLANid + $VMnic.VlanID + " "
	        }
	        Set-SCCustomPropertyValue -InputObject $VM -CustomProperty $CustomVLAN -Value $VLANid
	    }else{
	        Set-SCCustomPropertyValue -InputObject $VM -CustomProperty $CustomVLAN -Value $VMnics.VlanID
	    }
    }else {
		Set-SCCustomPropertyValue -InputObject $VM -CustomProperty $CustomVLAN -Value $VLANid
	}
    if($IP -ne ""){
        Set-SCCustomPropertyValue -InputObject $VM -CustomProperty $CustomIP -Value $IP
    }
}

a screendump of my powershell console, as you can see I am using the (Get-SCVMHostCluster).Nodes to get all virtual machines on these, also i am using a foreach (%) to run the population on each VM.

And this is how it looks in the VMM console,
