Hey @shanielh

Thanks for opening this issue - apologies for the delayed response here!

Support for this was added in hashicorp/terraform#14608 which shipped in Terraform v0.9.6. As such it's now possible to attach data disks to VM Scale Set using the following Terraform configuration:

  storage_profile_data_disk {
    lun               = 0
    caching           = "ReadWrite"
    create_option     = "Empty"
    disk_size_gb      = 10
    managed_disk_type = "Standard_LRS"
  }

There's more documentation available on the Terraform Website too.

Would it be possible to take a look and see if upgrading to the latest version of Terraform (currently 0.10.2) fixes this issue for you? In the interim I'm going to close this issue since it appears to be fixed, however please feel free to re-open it if there's still an issue here and we'll take a look :)

Thanks!

@tombuildsstuff , I have created azurerm_virtual_machine_scale_set and used the configuration below to attach the data disk to the VM Scale set.

 storage_profile_data_disk {
    lun           = 0
    caching       = "ReadWrite"
    create_option = "Empty"
    disk_size_gb  = 100
  }

It shows that the disk has been attached when I run the query below:

az vmss show \
>   --resource-group xxx-resourceGroup \
>   --namexxx-scaleset \
>   --query virtualMachineProfile.storageProfile.dataDisks
[
  {
    "caching": "ReadWrite",
    "createOption": "Empty",
    "diskSizeGb": 100,
    "lun": 0,
    "managedDisk": {
      "storageAccountType": "Standard_LRS"
    },
    "name": null,
    "writeAcceleratorEnabled": null
  }
]

Is the disk in prepared state or they have to be prepared as mentioned in this article - https://docs.microsoft.com/en-us/azure/virtual-machine-scale-sets/tutorial-use-disks-cli#prepare-the-data-disks?
If they need to be prepared, how do we go about preparing them using the terraform?
