Graphical Interfaces
A storage system can be managed through
multiple graphical interfaces:
FilerView administration tool
Operations Manager (formerly DataFabric
Manager)
Microsoft Windows interfaces such as
Computer Management for certain CIFS
functionality

Command Line Interface
The CLI is a powerful tool to administer storage
systems and can be accessed through:
Console
Telnet
Remote LAN Module (RLM)
FilerView CLI
Remote Shell (RSH)

Remote LAN Module
The RLM, which is available in some hardware
configurations, provides:
Remote access to your storage system
regardless of the system state
Continuous power and secure access

CLI Session Limitations
A storage system allows only one session and
one user at a time. Attempts to create additional
sessions will generate an error.
To create two separate sessions to use at the
same time:
telnet.distinct.enable
NOTE: If separate sessions are notcreated,
administrators must share the same session.
Too many users logged in! Please try again later. Connectionclosed.

Remote Shell
RSH allows you to issue console commands without a
console session.
To use RSH, enable it with the following:
options rsh.enable on
If there is a console password, you must modify/etc/hosts.equiv to allow access
Multiple RSH commands can be issued using the
following syntax:
UNIX
rsh [; ]
Windows
rsh l

Secure Shell
SSH is a network protocol that allows data
exchange over a secure channel. SSH also:
Allows for secure administrative access to the
storage system
Requires no license Can be implemented using the secureadmin
command or by using FilerView
For a complete description of the SSH feature,
see the System Administration Guide.

Console Editing
To edit files on the console:
1. Make a backup copy of the file.
2. Read the file using rdfile.
3. Write the file using wrfile.
IMPORTANT: When the wrfile command is issued, the original
file is deleted. Therefore, it is important to first use the rdfile
command. To append to a file withoutdeleting it, use wrfile a.

AutoSupport
The autosupport daemon monitors the storage
system's operations and sends automatic
messages to technical support. Technical
support contacts you with any reported issues.
AutoSupport messages are generated: When events occur on the storage system that
require corrective action
When you initiate a test message
When the system reboots
Once a week (usually after 12 a.m. on
Sundays)

Check Your Understanding
Name three ways to access a storage systems CLI.
Console, Telnet, RLM, RSH, SecureShare, and the FilerView CLI What is the URL to access FilerView?
http://[system name or IP]/na_admin
How can you view the system configuration for a FAS storagesystem? sysconfig [-v]
FilerView How can you configure a FAS storage system from a remote
adminhost? For UNIX, set up NFS and a mount an export of the root directory
For Windows, set up CIFS and access the \\filer\C$ share
When are AutoSupport messages generated?
Messages are generated when: Events occur on the storage system that require corrective action
The storage system reboots
You initiate a test message
Once a week, usually after 12 a.m. on Sundays
