How do you configure the thick/thin disk type for new OpenShift nodes on vSphere?

Solution Verified - Updated -

Issue

  • Trying to add a worker node to a cluster fails or takes up to 60 minutes to build.
  • The worker node starts out as being created with thin disk and then tries to change to thick disk and goes no further.
  • My datastore is set to thin, why are my machines created with thick?

Environment

  • Red Hat OpenShift Container Platform 4.x
  • vSphere 6.x, 7.x
