Setting up storage capability

Hello, I am new to Tablo. I have set everything up correctly except the storage. I have a Tablo dual Lite. How do I enable the storage capability? Thank you in advance.

During the setup, you should have seen a screen that told you to insert a hard drive. That would have been the time to do it, but you can just insert one afterward too and you should get a prompt to format it for Tablo’s use.
