Starting takeover by using System Manager
Data ONTAP FilerView or System Manager can be used for performing takeover or giveback
actions from a GUI. The example demonstrates how to perform these tasks by using System
Manager.
System Manager is a tool that is used for managing IBM N series that are available for at
extra cost. System Manager can be downloaded from the IBM NAS support site that is
available at this website:
