 If the option for using an ephemeral disk or OS cache placement or Temp disk placement is greyed out, you might have selected a VM size that doesn't have a cache/temp size larger than the OS image or that doesn't support Premium storage. Go back to the **Basics** page and try choosing another VM size.

 ## VM template deployment 
 You can deploy a VM with an ephemeral OS disk using a template. The process to create a VM that uses ephemeral OS disks is to add the `diffDiskSettings` property to Microsoft.Compute/virtualMachines resource type in the template. Also, the caching policy must be set to `ReadOnly` for the ephemeral OS disk. placement option can be changed to `CacheDisk` for OS cache disk placement.

 For scale sets, you use the same `--ephemeral-os-disk true` parameter for [az-vmss-create](/cli/azure/vmss#az-vmss-create) and set the `--os-disk-caching` parameter to `ReadOnly` and the `--ephemeral-os-disk-placement` parameter to `ResourceDisk` for temp disk placement or `CacheDisk` for cache disk placement.
