Hi,

You need to use the New-HardDisk command. Here is its documentation link: https://developer.vmware.com/docs/powercli/latest/vmware.vimautomation.core/commands/new-harddisk/#C...

In your case, I would do something like :

foreach ($vm in $vms){

  $vm | New-HardDisk -CapacityGB 10 [any_other_settings if needed to be added] | Out-Null

}

Regards,

Maya

Hi Maya,

Thanks for your reply..

If I want include 'Thin Provisioning' and create the disk on default location of the VM reside datastore.

Thanks in advance

Below is the script i'm trying 

$vms=Get-Content "c:\temp\batch.txt"
foreach ($vm in $vms)
{
$vm|New-HardDisk -CapacityGB 10
}

What do you have in $vm?
A String with the name of the VM?
Try doing

Get-VM -Name $vm | New-HardDisk -CapacityGB 10

Thanks LucD for your reply..

After adding the line as you mentioned getting following error.
