Re: vm to lun id number

To save the results to a CSV file use it like this

&{foreach($vminGet-VM){  $luns=Get-ScsiLun-VmHost$vm.Host-LunTypeDisk
  $vm.ExtensionData.Config.Hardware.Device|where {$_.gettype().Name-eq"VirtualDisk"} |%{    if("physicalMode","virtualmode"-contains$_.Backing.CompatibilityMode){      $disk=$_.Backing.LunUuid.Substring(10,32)      $luns|where {$_.CanonicalName.Split(".")[1] -eq$disk} |
      Select@{N="VM";E={$vm.Name}},
      @{N="LunId";E={[int](Select-String":L(?<lunID>\d+)$"-InputObject$_.RuntimeName).Matches[0].Groups['lunID'].Value}}    }  }
}} |Export-CsvC:\report.csv-NoTypeInformation-UseCulture

For me it seems to produce results. But mind, like I already stated, the script will run a very long time in a bigger environment.

What are the specs of your environment ? vSphere version, PowerCLI version ...
