You designate a workstation as an administration host to limit access to the storage system's root file system, to provide a text editor to edit configuration files, or to provide the ability to administer a storage system remotely.
During the setup process, you are prompted to designate a workstation on the network as an administration host. For more information about the setup process, see the Data ONTAP Software Setup Guide.
If you do not designate a workstation as an administration host, the storage system’s root file systems are available to all workstations on the network. As a result, any user can gain access to the storage system’s root file system and change or remove storage system configuration files in the /etc directory.
You can designate additional administration hosts after setup by modifying the storage system’s NFS exports and CIFS shares.
