Q:

Azure ADLS Gen2 not available

I am trying to create an Storage v2 Account with Data Lake Gen2 preview, but it is disabled from the Azure Wizard. 
As far as I have read it should be available for this setup?

A:

You can now specifiy that you want to use a hierarchical namespace at the creation of the storage account (via the portal in the advanced tab).
At the time the question has been raised it was in a gated preview, see the following documentation. You had to fill out a preview survey to get your subscription whitelisted for this feature.
