Last Sunday there appeared an interesting thread in the VMTN PowerCLI Community where one the questions was how to find all ‘Thin‘ virtual disks without passing via a virtual machine. The reason for this question was that most of the user’s virtual machines in Lab Manager are not registered on the vCenter Server.
My first idea was to use ‘Get-Datastore | Get-Harddisk‘ and then use the Extensiondata property to query the thinProvisioned property. Something like Arne did in his PowerCLI: Virtual Machine Disk (VMDK) info post. But that, unfortunately, doesn’t work since the Extensiondata property is $null in this case.
