Export vCenter Roles

Below is a powershell script to export vCenter roles to a ready to import set of commands.

Script below will not work without using PowerCLI or being connected to vCenter.

$viRolesList = Get-VIRole;
Foreach ( $role in $viRolesList ) {
     $roleName = $role.Name;
     $privilegeSet = $role | Get-VIPrivilege;

     Echo "New-VIRole -Name ""$roleName""" >> vRoles.txt;

     Foreach ( $privilege in $privilegeSet ) {
         $privilegeID = $privilege.ID;
         Echo "Set-VIRole -role ""$roleName"" -AddPrivilege `
         (Get-VIPrivilege -ID $privilegeID)" >> vRoles.txt;

Compare VM Name to VM Filename

In case you were blind sided by the vsphere 5.x bug fix that removes the storage vmotion feature that renames the VM’s folder and files. Below is a script that will at least help you identify the VMs that don’t match their file names.

Open powerCLI
Connect to your vcenter

$colorObject = get-wmiobject -class "Win32_Process" -namespace "root\CIMV2";
$vmCluster = Read-Host "Cluster Name";
$vmList = Get-Cluster $vmCluster | Get-VM;
Foreach ( $vm in $vmList ) {
 $vmView = $vm | Get-View;
 $vmView.Config.Files.VmPathName -match "^.*\/(.*)\.vmx$";
 $vmFName = $matches[1];
if ( $vm.Name -match $vmFName ) {
 write-host "$vm matches $vmFName";
 } else {
 write-host "$vm does not match $vmFName" -foreground "red";

PowerCLI and Storage

Below are some interesting sets of PowerCLI commands that will give you more information on your VM’s hard drives and your datastores.

The below will give you the total allocated hard drive space of all the VM’s in a cluster.

Get-Cluster "Cluster Name" | get-vm | Get-HardDisk | %{ $vmCapacity += $_.capacityKB }

The below will give you the Total Capacity, Free Space, and Usage of your datastores.

Get-Datastore | %{ $datastoreFreeSpace += $_.FreeSpaceMB }
Get-Datastore | %{ $datastoreTotalCapacity += $_.CapacityMB }
$datastoreUsageTotal = $datastoreTotalCapacity - $datastoreFreeSpace

write-host "Total Capacity: $datastoreTotalCapacity MBs"
write-host "Total Free Space: $datastoreFreeSpace MBs"
write-host "Total Usage: $datastoreUsageTotal MBs"

Get Total Space Used by VMs

The other day I was in need of finding out how much space my VMs actually take up.  Below are the commands I used in the vSphere PowerCLI to get that information.

$TotalDisk = 0;
#Get Sum of all Disks in TBs
Get-VM | Get-HardDisk | %{$TotalDisk+=[int]$_.CapacityKB}
$TotalDisk = $TotalDisk/1024/1024/1024;
echo "$TotalDisk TBs"
