VRA - block_device creation

Trying to use Terraform on top of VRA. I can create a vra_machine now and place it in the proper place with constraints.

What I’m trying to do now is add an additional hard drive to the machine using vra_block_device but I keep running into an error:

Error: Unable to provision disk as disk and compute storage are not compatible

Has anyone run into this? The working (and struggling) hypothesis is the 2 disks aren’t getting placed on the same datastore, but not sure. I’ve looked through the custom properties of the actual disks and they’re configured the same.
