Heads up — this article is over 125 months old. Some of the details may have changed since it was written.

There are multiple ways to tell if a virtual machine has thick or thin provisioned VM Disk. Below are some of the ways I am able to see this information:

VI Client (thick client)

  • Select the Virtual Machine
  • Choose Edit Settings
  • Select the disk you wish to check
  • look under Type

Web Client

Select your Host in Host and Cluster inventory -> Related Objects -> Virtual machines tab

  • Select your Host in Host and Cluster
  • click Related Objects
  • click Virtual machines tab

PowerCLI

  • Launch PowerCLI
  • type: connect-viserver
  • Run this command:
1

get-vm | Select Name, @{N="disktype";E={(Get-Harddisk $_).Storageformat}}
  • A list of all the virtual machines and disk types will be presented
