I'm not able to create a LUN, the create button is grayed out, and when hovering it says I need a license.

I installed a license, my request, and the email I received, said it's the VVols tech preview. Does this license not allow the use of iSCSI as well?

If that is the case, how do I request a new non-VVol license?

When I tried to request a new one from the site it said a license was already provided.
