I meant If there is no VMs or vmdks hosted on the datatastore. It is possible?

Thank you

great!! it does the work, now I have to add the function to unmount and dettach that datastore...

As soon as  i get it done I will post it here.

Feel free to share some code if already done.

Thank you for your support.

HI LucD,

Is there any way to create a loop so I can check all vcenter's datastores without having to specify the datastore name at the begining?

Thank you

found it on another of your posts^^

Thank you

VMware PowerCLI Forum - VMware {code}

last questions , I promise^^

Do you see an easy way to merge the check if datastore is umountable fonction ( Test if the datastore can be unmounted - LucD notes ) with the unmount it and dettached if true.

An easy way to run it over all vCenter's datastores and if it's unmountable do it and dettach it?

Thank you

Hola

I have commented all the checks except the VM and scratch check, I have a datastore empty,  but still getting the datastore is not empty result.

any hint?

Thank you

function Get-DatastoreUnmountStatus

{

   <#

.SYNOPSIS  Check if a datastore can be unmounted.

.DESCRIPTION The function checks a number of prerequisites

that need to be met to be able to unmount a datastore.

.NOTES  Author: Luc Dekens

.PARAMETER Datastore

The datastore for which you want to chekc the conditions.

You can pass the name of the datastore or the Datastore

object returned by Get-Datastore
