Hi Cruz, please read these options and decide.
1.) Delete the temporary aggr, volumes, and variables (for instance: Autosupport config, Date&Time config, CIFS domain, IP settings, ...) that you configured with OnCommand System Manager.
2.) Run the "setup" command (under physical CLI console session). To reconfigure Filer_name, VIF (ifgrp), IP. And later run the wizards according to your licences and environment (CIFS, NFS, LUN)
3.) The third option, MOST RADICAL, put in factory the equipment (backup your licences first), this action clean config, and FORMAT the disks, and DELETE your license (you must backup it first)
Under physical CLI console session, reboot the equipment and Press CTRL+C when appear "Press Ctrl-C for Boot Menu", then Press option 4) Clean configuration and initialize all disk.
Best regards
Dulis
