All data protocols on a netapp system require license codes for activation, and those license codes are only available to the original purchasor.
License codes for ONTAP 8.2 and later are locked to the serial number and older license codes are not compatible. License codes are also not transferrable, so you should not wipe the system unless you are the original purchasor and have those codes available.
As @aborzenkov says, the next steps depend what version and mode of ONTAP that system was previously running. If it is already running 8.3, control-c during the boot menu and choose option 4.
If not, and it was previously running 7-mode, you would need 8.2+ licenses issued for the system and then follow the instructions in this KB article to netboot it (preferably with 9.1P12) - https://kb.netapp.com/app/answers/answer_view/a_id/1031513/
Hope this helps!
