One of our objectives during our last VMware Horizon View deployment was to automate the creation of multiple Automatic Linked Clone pools. As a matter of fact, the Cmdlet linked to the pool’s creation (Add-AutomaticLinkedCLonePool) has two parameters which expect both the VM’s Full Path and the path to its Parent Folder.
The PowerShell Function below expects a VM as a parameter and returns the VM’s name, its Full Path and its Parent Folder’s path as shown in the synopsis. Just what we needed for our automation process!
#requires -version 2
Function Get-VMLogicalPath {
