Enabling OneFS 8.2.2 Max File Size?

To take advantage of the increased file size support of 16TBs, we just upgraded our Gen6 Isilon from OneFS 8.1.2 to 8.2.2. However, the 4TB file size limit appears to still be in place. Am I missing something? Is this something I can enable/correct myself, or is a Support ticket needed?

Thank you,

Bryan
