NetApp’s FAS series of storage arrays run a single operating system called Data ONTAP across all platforms – from the low end to the high end – though this operating system can run in one of two different modes. There’s the older “classic” mode, which the majority of FAS administrators are used to and which is now referred to as Data ONTAP 7-Mode, and there’s the new, scale-out mode that is simply called clustered Data ONTAP. While the two modes share similar administrative concepts and some similar commands, the two CLI operating environments are quite different in behaviors, structure, and feature sets. We’ll start by talking about 7-Mode.
Commands and Privilege Levels
Logging in (via SSH, telnet, or console) you are provided a simple administrative-level prompt:
The prompt contains the hostname of the controller (“mba-7m-1”) followed by a “>” which indicates that you are in the normal administrative privilege level.
From here, you can see the available commands by simply typing “?”:
? flexcache options smtape acpadmin fpolicy orouted snap aggr fsecurity partner snaplock arp ftp passwd snapmirror autosupport halt ping snapvault backup help ping6 snmp bmc hostname pktt software cdpd httpstat portset source cf ic priority sp charmap ifconfig priv stats cifs ifgrp qtree storage clone ifstat quota sysconfig cna_flash igroup radius sysstat config ipspace rdate system coredump iscsi rdfile timezone date key_manager reallocate traceroute dcb keymgr reboot traceroute6 df license restore ucadmin disk lock restore_backup ups disk_fw_update logger revert_to uptime dns logout rlm useradmin download lun route version du man routed vfiler dump maxfiles rshstat vlan echo mt sasadmin vmservices ems nbtstat sasstat vol environment ndmpcopy savecore vscan exportfs ndmpd sectrace wcc fcadmin ndp secureadmin wrfile fcnic netdiag setup ypcat fcp netstat sftp ypgroup fcstat nfs shelfchk ypmatch fcvi nfsstat sis ypwhich file nis
This shows you all of the commands available for this administrator privilege level.
There are two additional privilege levels available: advanced and diag. You can change to these levels using the “priv set” command.
mba-7m-1> priv set advanced Warning: These advanced commands are potentially dangerous; use them only when directed to do so by NetApp personnel. mba-7m-1\*> mba-7m-1\*> priv set diag Warning: These diagnostic commands are for use by NetApp personnel only. mba-7m-1\*>
The asterisk after the hostname indicates that you are in either advanced or diag privilege mode. There’s no visual distinction between the two modes, but you can find out which one you are in by typing simply “priv”:
mba-7m-1\*> priv diag mba-7m-1\*>
More commands are available within the higher privilege levels than in the normal admin level.Advanced:

Typing either “priv set” without specifying a privilege level, or “priv set admin” will take you back to the default admin privilege level.

Command Syntax and Help
You can see the syntax for a command by passing it the “-?” flag.
mba-7m-1> arp -? usage: arp [-n] arp [-n] -a arp -d arp -s [temp] [pub] arp -F
Even better, administrative-level commands have a full manual (man) page available explaining the operation of the command in detail:
mba-7m-1> man arp na_arp(1) na_arp(1) NAME na_arp - Address resolution display and control SYNOPSIS arp [-n] hostname arp [-n] -a arp -d hostname arp -s hostname ether_address [ temp ] [ pub ] DESCRIPTION The arp command displays and modifies the tables that the address resolution protocol uses to translate between Internet and Ethernet addresses. With no flags, arp displays the current ARP entry for hostname. The host may be specified by name or by number, using Internet dot notation. OPTIONS -a Displays all of the current ARP entries. -d Deletes an entry for the host called hostname. -n IP addresses are displayed instead of hostnames. -s Creates an ARP entry for the host called hostname with the Ethernet address ether_address. The Eth- ernet address is given as six hex bytes separated by colons. The entry not will be permanent if the words following -s includes the keyword temp. Tem- porary entries that consist of a complete Internet address and a matching Ethernet address are flushed from the arp table if they haven't been referenced in the past 20 minutes. A permanent entry is not flushed. If the words following -s include the keyword pub, the entry will be "published"; that is, this system will act as an ARP server, responding to requests for hostname even though the host address is not its own. HA CONSIDERATIONS In takeover mode, each node in an HA pair maintains its own ARP table. You can make changes to the ARP table on the live node, or you can make changes to the ARP table on the failed node using the arp command in partner mode. However, the changes you make in partner mode are lost after a giveback. VFILER CONSIDERATIONS When run from a vfiler context, (for example, via the vfiler run command), arp operates on the concerned vfiler. As currently all vfilers in an ipspace share an arp table, arp operates on the arp table of the concerned vfiler's ipspace. SEE ALSO na_ifconfig(1), na_partner(1), na_ipspace(1), na_vfiler(1), RFC1483. 6 June 1998 na_arp(1)
In Data ONTAP 7-mode, commands cannot be tab-completed in the shell, nor can they be abbreviated as with some other shells. Each command needs to be fully specified in order for it to be recognized.
Navigation and Editing
Command-line editing and navigation utilizes the standard keystrokes and combination previously discussed in CLI Efficiency: Common Basics
While you can navigate through your previously-entered commands using the up and down arrows, or Ctrl+n and Ctrl+p, there is no “history” command to simply display the contents of that history.
You can enter multiple commands on the same command line by separating each command with a semi-colon. The commands will then be executed in order of entry.
mba-7m-1> echo "help"; echo "I'm being held prisoner"; echo "in a terminal emulator" help I'm being held prisoner in a terminal emulator
