IMPORTANT INFORMATION ABOUT YOUR NEW TAPE DRIVE
For the most up-to-date information about supported SAS HBAs and cabling
configurations, refer to www.hp.com/go/connect and be sure to check the details of
the specific tape drive and server combination that you require.
The most cost-effective way of connecting the tape drive to an HP ProLiant server is
to use the split cable supplied with the drive. However, be aware that installation
decisions require a clear understanding of your server’s current SAS configuration.
This option is not appropriate if drive portability and ease of connection are important
to you. It requires a spare PCI slot through which you will thread the SAS cable.
• With some servers you can connect to a spare internal SAS connector on the
SAS controller. This is a straightforward installation and recommended.
• With servers that do not have a spare internal connector, you will need to rewire
hard disk drive bays. In a few instances, you may also lose the use of one of the
hard disk drive bays. Caution is advised for this installation. Do NOT use this
cabling option, if the hard disk drive bay is already occupied or will be required for
future use.
The simplest way of connecting a tape drive to your HP server is to purchase and
install one of the supported HBAs, see www.hp.com/go/connect. This option may
also be used with non-HP servers as long as the third-party manufacturer supports
the HP SAS controller installed in their server.
For detailed, step-by-step installation instructions, refer to the “User Guide” from the
Documentation link on the HP StorageWorks CD-ROM.
1Refer to www.tandbergdata.com
Before you install your tape drive, always refer to www.tandbergdata.com to find
out:
• Is connection to your SAS server supported?
• Can you connect to the host SAS controller or do you need to purchase an
additional HBA?
• If you connect to a new HBA, can you use the supplied cable or must you
purchase an additional cable.
This poster describes how to connect a Tandberg LTO-3 and LTO-4 SAS tape drive
to an external port using a purchased cable.
WARNING: To avoid personal injury or damage to the server or tape drive,
disconnect your server from the mains power supply before installing the tape
drive. To avoid damage to server or tape drive observe all recommended
anti-static and power-grounding precautions, as specified in your server and
tape drive manuals.
2Connect to an external SAS port
The following instructions are valid ONLY for servers with an HBA that supports
external SAS ports. You must purchase a supported HBA and cable, if you do not
already have a SAS card installed. See www.tandbergdata.com for
recommended products. You need a spare PCI slot for the new HBA.
1. Connect the SAS cable to the server
2. Connect the cables to the tape drive
3. Power up the tape drive and server
Switch on the tape drive and power up the server. Watch the boot screen carefully
after installation. Check to see that the new SAS tape drive is listed in the boot
sequence.
If there are any error or unexpected messages go back and check the SAS cabling
carefully.
4. Install drivers
For Windows systems, download the latest drivers from www.tandbergdata.com.
For other operating systems, patch to the latest version of the operating system,
following the instructions in the patch documentation.
5. Upgrade backup software
Always upgrade your software application to ensure it works correctly with the 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.

3Hardware encryption and your Tandberg LTO-4
tape drive
Your Tandberg LTO-4 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 only on Tandberg
LTO-4 1.6 TB media; media encrypted on a Tandberg LTO-4 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. The
software supplied with the tape drive provides this support. See
www.tandbergdata.com for an up-to-date list of backup software.
• 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
Tandberg Data Support will be able to access the encrypted data.
5Understanding the LEDs
1 Clean – amber
• On: cleaning cartridge in use
• Off: the drive does not require
cleaning
• Flashing: the drive needs cleaning
2 Tape – amber
• Off: no fault has been detected
• Flashing: the cartridge currently in
the drive is faulty (damaged or
unsupported). Discard the cartridge.
3 Drive – amber
• Off: no fault has been detected
• Flashing: the drive mechanism has
detected a hardware error
4 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
4Choosing and looking after media
Your high-performance tape drive works best with high-performance Tandberg LTO
media. For optimum performance always use a data cartridge that matches the
specification of your tape drive (see table).
Table: Tandberg LTO data cartridge compatibility
* Capacity assumes 2:1 compression.
The recommended cleaning cartridge is the Tandberg 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.
• Keep media in the case provided.
• Follow the temperature, humidity and acclimitization 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 www.tandbergdata.com.
