PowerCLI Script for VM Disk over 250GB

So you may be mid-planning for your upgrade to 5.x but still adding to your current environment. As you add datastores the question of block size comes up. Here is a script to list any VMs with a disk greater than 250GB (yes, 256 is the magic number but lets be honest...who really makes a 256GB disk). If you don't have any VMs greater than 250, stick with the 1MB so conversion to VMFS5 is just a little easier.

$data = @()

$vc ="YOUR VC"

Connect-VIServer $vc

$vms =Get-VM

foreach($vmin$vms)

{

     $disks=$vm | Get-HardDisk | where {$_.CapacityKB -gt 262144000}

     if($disks-ne$null)

     {

          foreach($din$disks)

          {

           $myItem="" | SelectVM , Disk , Size

           $myItem.VM=$vm.Name

           $myItem.Disk=$d.ExtensionData.DeviceInfo.Label

           $myItem.Size= [math]::round(($d.CapacityKB/ 1048576),2)

           $data+=$myItem

          }

     }
