Hi Pepijnve,
Sorry that the simulator does not contain the S3 license to test out the new S3 functionality in ONTAP 9.8.
You can obtain a free S3 evaluation license on the NetApp Evaluation Central site. NOTE: The site requires NetApp login credentials.
Admin edit:
Your sales team should be able to help obtain the above mentioned evaluation license(s). The hyperlink to it has been removed.
