=== ESX Datastore to LUN Mapping === | |||
Its bizarrely difficult to be able to map VMware presented datastore names to the underlying LUN's, despite the fact that its readily available via the VI Client. The following was adapted from the work of ''Catman'' found in this forum thread - http://communities.vmware.com/thread/240466#240466. As I expect to maybe want some of the other fields available during the working my notes from working through this are to be found [[Datastore to LUN Mapping (PowerCLI)|here]] | |||

if ($objViewESXstorageSys.FileSystemVolumeInfo.MountInfo[$MountIdx].Volume.Type -eq "VMFS" ) { | |||
$objVolume = $objViewESXstorageSys.FileSystemVolumeInfo.MountInfo[$MountIdx].Volume | |||
$ExtentCount = $objVolume.Extent.Length | |||
for ($ExtentIdx = 0; $ExtentIdx -lt $ExtentCount; $ExtentIdx++ ) { | |||
$objExtent = $objVolume.Extent[$ExtentIdx] | |||
# Match extent name to disk name | |||
if ($objExtent.DiskName -eq $objSCSIdisk.CanonicalName) { | |||
Write-Host($objSCSIdisk.Vendor + " " + $objSCSIdisk.Model + " " + $objSCSIdisk.CanonicalName + "`t" + $objVolume.Name) | |||

Gives an output a bit like this... | |||
