FAS8020 Converted to CDOT and Upgraded to OnTap 9 - Missing e0c and e0d Ports

Hi

We have zeroed our FAS8020, converted to clustered, upgraded to OnTap 8.3 from 8.2.4 and then upgraded to OnTap 9.1

Previously we didn't have an Cluster Interconnect as it was 7 Mode. I used e0a and e0b fibre ports to interconnect. I want to use e0c and e0d on each node for my data network but they do not show in OnCommand management and they do not show when I do ana ifconfig -a

I can't find anything on the internet about it.

Please help.
