Scripting SAN volume and LUN creation

I am trying to script the creation of SAN volume and then a LUN underneath using the CLI.  The first problem is that there is no Storage Type option from the CLI that I can find.  So creating the SAN volume with one command and then creating the LUN with a second command does not seem to be an option.

The second issue is if I try to just create the LUN and the volume at the same time using lun create, there is no option to select the aggregate that I want to use.  I want the script to select a particular aggregate for this process.

Is there a way to do this without using WFA?  Does Powershell have this capability?  I am running CDOT 8.3.2P4.

Thanks,

Jon
