Use of administrative privilege levels
ONTAP commands and parameters are defined at three privilege levels: admin, advanced, and diagnostic. The privilege levels reflect the skill levels required in performing the tasks.
Most commands and parameters are available at this level. They are used for common or routine tasks.
Commands and parameters at this level are used infrequently, require advanced knowledge, and can cause problems if used inappropriately.
You use advanced commands or parameters only with the advice of support personnel.
Diagnostic commands and parameters are potentially disruptive. They are used only by support personnel to diagnose and fix problems.
