LTO Half-Height SAS

External Tape Drive

Quick Start Guide

Overview

This document describes how to unpack and install an

Overland LTO Half-Height SAS External Tape Drive to

an external port using a purchased cable.

WARNING: To reduce the risk of electric shock or damage

to equipment, always remove any power cords while

working with the unit.

AVERTISSEMENT: pour réduire le risque de choc

électrique ou endommagement de l'équipement, retirez

toujours les cordons électriques en travaillant avec l'appareil.

CAUTION: While working with the unit, observe standard

Electrostatic Discharge (ESD) precautions to prevent

damage to micro-circuitry or static-sensitive devices.

NOTE: Cables are not supplied in the External Tape Drive

product kits. These cables must be purchased separately.

Before starting, it is essential that you activate your

Overland warranty. Technical and warranty support are

not available until this is done:

1. Go to the Overland Storage web site

(http://www.overlandstorage.com/).

2. Select Service & Support > My Products.

3. At the Site Login, enter your e-mail address and

password, and click GO.

NOTE: If you are not yet a member, click “New member?”

and follow the instructions given. It’s free and easy!

4. Click the Register New Product button.

5. Fill in the information and click Submit.

IMPORTANT: Within three business days, you will receive

an e-mail from Overland with your warranty certificate.

Follow the instructions included to complete the process.

Introduction

Before you install your tape drive, make sure:

•That the connection to your SAS server is supported.

•You are able to connect to the host SAS controller via

an installed host bus adaptor (HBA).

•You have the correct cable (available separately) to

attach the tape drive to the HBA.

Preparing The Host

SAS HBA Card

The following instructions are valid ONLY for servers

with an HBA that supports external SAS ports.

If you do not already have a SAS HBA card installed, you

must purchase a supported HBA card along with a

matching cable. You need a spare PCI slot for the card.

Drivers

For Windows systems, download the latest drivers from

the HP tape drive drivers web site. For other operating

systems, patch to the latest version of the operating

system, following the instructions in the patch

documentation.

Backup software

It is recommended to upgrade your backup software

application to ensure it works correctly with the new

external tape drive. We do NOT recommend native

backup applications, such as Windows Backup, because

they do not support the full features of the tape drive and

may cause performance problems.

NOTE: Some backup applications require you to use their own

drivers. Refer to the documentation of your software

application to ensure you are using the recommended driver.

Connecting the Tape Drive

CAUTION: Turn off and remove the power cords from the

server.

1. Connect the SAS cable to the server HBA card.

The cable connector may be different than the one

pictured depending on the HBA card used.

*10400303001*

2. Connect the SAS cable (1) and power cord (2) to the

tape drive.

3. Power up the tape drive and server.

a. Power on the tape drive using the power button

located at the front of the tape drive.

b. Check the Ready LED on the front panel to make

sure the tape drive is ready for use.

c. Plug in and turn on the host server.

Watch the boot screen carefully during the boot

process. Check to see that the new tape drive is

listed in the boot sequence.

NOTE: If there are any error or unexpected messages, go

back and check the SAS cabling carefully.

Checking Product Performance

If performance is not meeting expectations and you are

not meeting your backup window, check for bottlenecks

in your system architecture.

What causes bottlenecks? Review the numbered items

that follow which match the graphic numbering below.

1. We recommend direct connection for LTO-4 and

LTO-3 tape drives. If you back up over a network,

anything less than Gigabit Ethernet may limit

performance.

2. A single disk may limit backup performance. Have

disks in parallel (for example, RAID 5) if possible or, if

your backup application supports interleaving of data,

back up streams from multiple sources.

3. Use the latest version of your backup application.

Native backup applications, such as Windows backup,

may limit performance.

4. For optimum performance, use LTO-4 R/W and

WORM cartridges with LTO-4 tape drives, LTO-3 R/W

and WORM cartridges with LTO-3 tape drives, and

LTO-2 R/W cartridges with LTO-2 tape drives.

Hardware Encryption

An LTO-5 external SAS tape drive provides the ability to

hardware encrypt your data, applying the strongest level

of AES industry-standard encryption and protecting the

data from unauthorized access and use. Encryption is

supported on LTO-5 (3 TB) and LTO-4 (1.6 TB) media;

media encrypted on a LTO drive can only be read on a

compatible Ultrium tape drive that supports hardware

encryption.

Hardware encryption can be used with or without

compression and without speed or capacity penalties.

IMPORTANT: Hardware encryption is a powerful feature, but

should be used with care. If you need to import your media

onto another machine or to recover after disaster you will be

required to enter an encryption key.

•Hardware encryption is turned off by default and is

switched on by settings in your backup application,

where you also generate and supply the encryption

key.

•Your backup application must support hardware

encryption for it to work.

1. Power Button

•You should keep a record or backup of your encryption

keys and store them in a secure place separate from

the computer running the backup software.

•If you are unable to supply the key when requested to

do so, neither you nor Overland Storage will be able to

access the encrypted data.

Understanding LEDs

Media Choice and Care

Your high-performance tape drive works best with high-

performance LTO media. For optimum performance

always use a data cartridge that matches the

specification of your tape drive (see table).

The recommended cleaning cartridge is the LTO

universal cleaning cartridge. This cartridge is designed to

work with any Ultrium drive and may be used for up to

50 cleans.

It Pays to Look After Your Media

Many tape drive and backup failures are caused by

damaged or badly handled tape media. Follow these

steps:

•Keep media in the case provided.

•Follow the temperature, humidity, and

acclimatization guidelines on the media packaging.

•Avoid dropping it or rough handling, as this is likely to

damage the cartridge.

•Inspect it regularly for damage.

•Do not exceed normal cartridge life (260 full volume

backup or restore operations).

For detailed information on media care and best practice

and to order online, refer to Overland's web site.

1. Encryption – blue/amber

•On (blue or amber): at

power on.

•Off: drive is idle with no

encryption key.

•Off with Ready LED flashing:

drive is reading/writing

unencrypted data or

unloading cartridge.

•On (blue): drive is idle with

encryption key.

•On (blue) with Ready LED

flashing: drive is reading/

writing encrypted data.

•Blue and Amber flashing

alternately: encryption or

decryption error.

2. Clean – amber

•On: cleaning cartridge in

use.

•Off: the drive does not

require cleaning.

•Flashing: the drive needs

cleaning.

3. Tape – amber

•Off: no fault has been

detected.

•Flashing: the cartridge

currently in the drive is faulty

(damaged / unsupported).

Discard the cartridge.

4. Drive – amber

•Off: no fault has been

detected.

•Flashing: the drive

mechanism has detected a

hardware error.

5. Ready – green

•On: the drive is ready for

use.

•Off: the drive power is off or

there was a failure during

self-test.

•Flashing: the drive is busy.
