SCv3020 storage can't manage unassigned disks

Hello.

I have SCv3020 storage, and I am tried to setup 5 of hard drives then it gives me error:

No disks eligible to be added to this disk folder could be found.

I attached screen shot of them. Checked the unassigned reason, and it says: Unlicensed.

Please give me some information how can I solve the solution.

And how can I check that hard disk is compatible with my storage?
