I'm assuming you are looking for the command to place the ONTAP console in the advanced context.
The command you need is 'priv set advanced'
You can return the console to the normal admin context with 'priv set admin' or 'priv set' for short.
Advanced context gives you access to commands that can prevent your Filer from working properly if you don't know what you are doing.
The man pages have further information and if you are unsure about the implications of using a certain advanced command you may want to post more questions on the community pages or contact NetApp Global Support.
