I wanted to know how many disks in our environment are thin provisioned, so I wrote a quick function to export that list to a CSV file.

I have it pull the VM name, vmdk path & name, Size in GB, and if it’s Thin Provisioned (Boolean, which should always be true).


Just copy & paste this into a .ps1 file and run it (or download link at bottom). The initial instantiation of $vms takes a while, depending on the size of your environment, but the rest goes quickly. Make sure you’re connected to a host or vcenter before you run it, or you won’t get anything.

To change where the file is saved, simply change the path in line 27 to the destination of your choice.
