VMware find orphan vmdk

Finding orphaned VMDK’s using PowerCLI

Here is a PowerCLI script I use to find all orphaned VMDK’s in my vCenter environment.

$arrayVC = "virtualcenter2"

Foreach ($strVC in $arrayVC)
{
 Connect-VIServer $strVC 
 $arrUsedDisks = Get-VM | Get-HardDisk | %{$_.filename}
 $arrUsedDisks += get-template | Get-HardDisk | %{$_.filename}
 $arrDS = Get-Datastore
 Foreach ($strDatastore in $arrDS)
 {
 $strDatastoreName = $strDatastore.name
 $ds = Get-Datastore -Name $strDatastoreName | %{Get-View $_.Id}
 $fileQueryFlags = New-Object VMware.Vim.FileQueryFlags
 $fileQueryFlags.FileSize = $true
 $fileQueryFlags.FileType = $true
 $fileQueryFlags.Modification = $true
 $searchSpec = New-Object VMware.Vim.HostDatastoreBrowserSearchSpec
 $searchSpec.details = $fileQueryFlags
 $searchSpec.sortFoldersFirst = $true
 $dsBrowser = Get-View $ds.browser
 $rootPath = "["+$ds.summary.Name+"]"
 $searchResult = $dsBrowser.SearchDatastoreSubFolders($rootPath, $searchSpec)
 $myCol = @()
 foreach ($folder in $searchResult)
 {
 foreach ($fileResult in $folder.File)
 {
 $file = "" | select Name, FullPath 
 $file.Name = $fileResult.Path
 $strFilename = $file.Name
 IF ($strFilename)
 {
 IF ($strFilename.Contains(".vmdk")) 
 {
 IF (!$strFilename.Contains("-flat.vmdk"))
 {
 IF (!$strFilename.Contains("delta.vmdk")) 
 {
 $strCheckfile = "*"+$file.Name+"*"
 IF ($arrUsedDisks -Like $strCheckfile){}
 ELSE 
 { 
 $strOutput = $strDatastoreName + " Orphaned VMDK Found: " + $strFilename
 $strOutput
 } 
 }
 } 
 }
 }
 }
 } 
 } 
}
