Re: Reporting on a LUNs preferred path

Try something like this

$dsTab = @{}
foreach($ds in (Get-Datastore | where {$_.Type -eq "VMFS"} )){
    $ds.ExtensionData.Info.Vmfs.Extent | %{
        $dsTab.Add($_.DiskName,$ds.Name)
    }
}
foreach($esx in Get-VMHost){
     foreach($lun in (Get-ScsiLun -VMHost $esx)){
        Get-ScsiLunPath -ScsiLun $lun |
        Select @{N="Host";E={$esx.Name}},@{N="LUN";E={$lun.CanonicalName}},LunPath,Preferred,
                @{N="DS";E={$dsTab[$_.ScsiCanonicalName]}}
     }
}
