Determining Paths to vSphere Inventory Objects
The following PowerShell function uses vSphere PowerCLI to return the full path to a vSphere inventory
object.
# VVGetInventoryPath
# Parameters
# $InvObject Inventory object in vSphere PowerCLI.
#
# Examples
# VVGetInventoryPath (Get-VM -name myVM)
# VVGetInventoryPath (Get-ResourcePool | Select -first 1)
function VVGetPath($InvObject){
if($InvObject){
$objectType = $InvObject.GetType().Name
$objectBaseType = $InvObject.GetType().BaseType.Name
if($objectType.Contains("DatastoreImpl")){
Write-Error "Use the VVGetDataStorePath function to determine datastore paths."
break
}
if(-not ($objectBaseType.Contains("InventoryItemImpl") -or
$objectBaseType.Contains("FolderImpl") -or
$objectBaseType.Contains("DatacenterImpl") -or
$objectBaseType.Contains("VMHostImpl") ) ){
Write-Error ("The provided object is not an expected vSphere object type. Object type
is " + $objectType)
break
}
$path = ""
# Recursively move up through the inventory hierarchy by parent or folder.
if($InvObject.ParentId){
$path = VVGetPath(Get-Inventory -Id $InvObject.ParentId)
} elseif ($InvObject.FolderId){
