LTO-5 Half-Height SAS Tape Drives 11

2 Verify installation

Once you have installed the drive hardware, check that drivers have been
installed correctly and you have the correct version of backup software, and
verify that the tape drive is functioning properly before you store your valuable
data.

1. Switch on the server.

2. The tape drive will run its hardware self-test, which takes about 5 seconds.
If self-test passes, the green Ready LED flashes and then shows steady
green. If the test fails, the Drive and Tape LEDs flash, while the Ready and
Clean LEDs are off. This continues until the drive is reset. See

"Understanding LED sequences" on page 27 for more information about

front panel LEDs.

● If you installed drivers before connecting the tape drive (Windows

only)

The tape drive should be detected automatically and the correct drivers
used.

● Installing drivers after connecting the tape drive (Windows only)

If you have not already installed drivers, install the driver according to the
supplied documentation

in the driver's folder.

● Installing drivers (other operating systems)

Drivers are included with the operating system and should be loaded
automatically.

NOTE:
Certain backup applications require you to use their own Tape driver.

3. Verify that the tape drive installation was successful.

4. For all operating systems ensure that you have downloaded any upgrades
necessary for your backup application.

Figure 4: Ejecting a cartridge

1. Eject button

2. The drive will complete its current task, rewind the tape to the beginning, and
eject the cartridge. The rewind process may take up to 10 minutes. The
Ready LED will flash to indicate that the unload is still in progress.

3.3 Removing power from the drive

To ensure reliable operation, do not remove power from the drive during read,
write, fast-search, load and unload activities.

LTO-5 Half-Height SAS Tape Drives 15

4 Cautions concerning backup

In this chapter:

● "Ejecting the data cartridge after backup" on page 15

● "Data compression rate" on page 15

● "Backup performance/capacity" on page 16

● "Points to note during system configuration" on page 16

4.1 Ejecting the data cartridge after backup

● Do not leave the data cartridge in this product.

Doing so makes the data cartridge wear faster, because the longer it is used,
the faster it wears. The tape recording surface of the data cartridge is
exposed when inserted in this product and if it is left in this state for a long
time it will easily be affected by suspended particles of dust. Insert the data
cartridge just before the backup operation, and remove it immediately after
the operation.

● Do not turn off the power with the data cartridge inserted.

If the power is turned off with the data cartridge inserted, it takes a while
before this product can be used after the next power-on.

4.2 Data compression rate

This product has a data compression function included in the hardware.

Although the data compression rate is approximately 200%, it varies depending
on the data content.

Data that has already been compressed by software is not effected by this
product.

Some backup software has a data compression function prior to transfer,
however, do not compress data by software if the hardware compression
function is on.

16 LTO-5 Half-Height SAS Tape Drives

Backup performance/capacity

4.3 Backup performance/capacity

The backup performance and backup capacity that can be used in one data
cartridge varies depending upon the following factors:

● The conditions (attrition, dust, etc.) of the recording surface of the data

cartridge to be used

● The dust and dirt condition of the product's magnetic head

● The data compression rate

● The workload on the server

4.4 Points to note during system configuration

When repeatedly using a single data cartridge, all the data can be lost if the
backup fails. Also, if a backup data cartridge becomes damaged, the data
cannot be recovered.

Damage in the event of a failure can be minimized if two or more data cartridges
are used for backup operation. For example, use different data cartridges for
each day of the week.

LTO-5 Half-Height SAS Tape Drives 17

5 Use the correct media

In this chapter:

● "Cartridges" on page 17

● "Cartridge life" on page 18

● "Write protecting cartridges" on page 19

● "WORM data cartridges" on page 20

● "LTO-5 tape drives and encryption" on page 20

● "Cleaning the tape drive" on page 23

● "Handling cartridges" on page 23

● "Storage environment" on page 24

5.1 Cartridges

5.1.1 Cleaning cartridges

Use the universal cleaning cartridge. It may be used for up to 50 cleans.

5.1.2 Data cartridges

LTO–5 tape drives use LTO Ultrium 5 tape cartridges. These are single-reel
cartridges that match your drive's format and are optimized for high capacity,
throughput and reliability. Compatible media can be recognized by the Ultrium
logo, which is the same as the logo on the front of your drive. Do not use other
format cartridges in your tape drive and do not use LTO Ultrium 5 cartridges in
other format tape drives.

To achieve best performance we recommend using only “Fujitsu — Preferred
Quality” LTO Media cartridges.

For optimum performance always use LTO Ultrium 5 data cartridges because
they match the specification of your tape drive. A lower specification will have a
lower transfer speed and may not support write activities; a higher specification
will not support read or write.

18 LTO-5 Half-Height SAS Tape Drives

Cartridge life

The drive supports the following LTO data cartridges:

5.2 Cartridge life

To avoid a backup failure due to worn media, replace the media (data cartridge)
before either of the following occur:

● After one year of use

● After being used 1000 times

The lifespan of media varies depending on the environment (temperature,
humidity, dust, etc.) and operating conditions of this product.

I IMPORTANT:

The data cartridge is a replaceable part. Worn media can cause
problems such as magnetic tape surface damage, dirty magnetic head,
many media errors, and so on. See also "Problems with cartridges" on

page 32.

Write protecting cartridges

5.3 Write protecting cartridges

W WARNING!

Always remove the cartridge from the tape drive before you change the
write protection.

If you want to protect the data on a cartridge from being altered or overwritten,
you can write protect the cartridge.

● To write protect a cartridge, push the switch to the right to prevent any data

recording on the cartridge. Note the padlock on the tab that indicates that the
cartridge is protected.

● To write enable a cartridge, push the switch to the left to allow data recording

on the cartridge. Figure 5 on page 19 illustrates the location of the write­protect tab.

Figure 5: Write protecting a cartridge

1. Write-protect tab

20 LTO-5 Half-Height SAS Tape Drives

WORM data cartridges

V CAUTION:

Write-protection will not protect your cartridges against magnets. Write­protection will not prevent a cartridge being erased by bulk-erasure or
degaussing. Do not bulk erase LTO format cartridges. This will destroy
pre-recorded servo information and make the cartridge unusable.

5.4 WORM data cartridges

The LTO–5 tape drive includes support for both re-writable and Write-Once,
Read-Many, WORM, data cartridges. WORM cartridges provide an enhanced
level of data security against accidental or malicious alteration of data on the
tape cartridge. The WORM data cartridge can be appended to maximize the full
capacity of the tape cartridge, but the user will be unable to erase or overwrite
data on the cartridge. Any attempt to modify a WORM cartridge to enable
writing over existing data will result in the media becoming permanently write
protected. It should still be readable in a WORM drive, depending upon the
severity of the tampering, but no further appended backups will be possible.

WORM data cartridges are clearly identified by their distinctive, two-tone
cartridge color. They can only be used with LTO tape drives that support the
WORM feature.

To check whether your backup or archive software application supports WORM
cartridges, refer to the software manual.

5.5 LTO-5 tape drives and encryption

The LTO–5 tape drive includes hardware capable of performing data encryption
at full speed while writing data, and decrypting when reading.

Encryption is the process of changing data into a form that cannot be read until
it is deciphered, protecting the data from unauthorized access and use. LTO–5
tape drives use the strongest version of the industry-standard AES encrypting
algorithm to protect your data.

To make use of this feature you need:

● A backup application that supports hardware encryption

● LTO Ultrium 5 media (recommended) or LTO Ultrium 4 media; no encryption

will be performed when writing earlier generations of tape

LTO-5 Half-Height SAS Tape Drives 21

LTO-5 tape drives and encryption

5.5.1 When should I use encryption?

Your company policy will determine when you need to use encryption. For
example, it may be mandatory for company confidential and financial data, but
not for personal data. Company policy will also define how encryption keys
should be generated and managed. Backup applications that support
encryption will generate a key for you or allow you to enter a key manually.

NOTE:
Encryption with keys that are generated directly from passwords or
passphrases may be less secure than encryption using truly random keys. Your
application should explain the options and methods that are available. Please
refer to your application's user documentation for more information.

5.5.2 How do I enable encryption?

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 this feature
to work.

5.5.3 What happens if I don't remember the key?

If you are unable to supply the key when requested to do so, neither you nor
Technical Support will be able to access the encrypted data.

This guarantees the security of your data, but also means that you must be
careful in the management of the encryption key used to generate the tape.

W WARNING!

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.

5.5.4 Does encryption affect tape drive performance?

Hardware encryption can be used with or without compression and without
speed or capacity penalties.

22 LTO-5 Half-Height SAS Tape Drives

LTO-5 tape drives and encryption

5.5.5 Does the tape drive encrypt media in an earlier LTO

format?

Encryption is supported only on LTO Ultrium 5 media and LTO Ultrium 4 media.

Encrypted LTO Ultrium 5 and LTO Ultrium 4 tapes can be read on any
compatible LTO tape drive that supports hardware encryption. (LTO-5 tape
drives can read and write encrypted LTO Ultrium 5 media and LTO Ultrium 4
media.)

Hardware encryption is not supported on any earlier LTO media, such as LTO
Ultrium 3 media.

5.5.6 Where can I get more information?

For detailed instructions about enabling encryption please refer to the
documentation supplied with your backup application. This will also highlight
any default states, for example when copying tapes, that may need changing if
using encrypted tapes.

LTO-5 Half-Height SAS Tape Drives 23

Cleaning the tape drive

5.6 Cleaning the tape drive

Perform magnetic head cleaning as follows:

● Periodically (once every three months)

● If the Clean LED flashes

You must use the Ultrium Universal Cleaning cartridge with LTO-5 tape drives,
as other cleaning cartridges will not load and run.

To clean the tape drive:

1. Insert the Ultrium Universal Cleaning cartridge.

2. The drive will carry out its cleaning cycle and eject the cartridge on
completion (which can take up to 5 minutes). During the cleaning cycle the
orange Clean LED will be on solidly and the green Ready LED will flash.

Each Ultrium universal cleaning cartridge cleaning cartridge can be used up
to 50 times with Ultrium tape drives. If the cleaning cartridge is ejected
immediately with the Tape LED on, it has expired.

5.7 Handling cartridges

● Do not touch the tape media.

● Do not open the drive door and touch the tape media.

● Do not attempt to clean the tape path or tape guides inside the cartridge.

● Do not leave cartridges in the drive. The tape loses tension in the power-off

state, which can lead to problems, particularly if the drive has been moved.

● Do not leave cartridges in excessively dry or humid conditions.

● Do not leave cartridges in direct sunlight or in places where magnetic fields

are present (for example, under telephones, next to monitors or near
transformers).

● Do not drop cartridges or handle them roughly.

● Stick labels onto the label area only.

● Do not bulk erase (or degauss) LTO format cartridges because this will

render them unusable.

● Attach the label at the location shown in the following figure.

24 LTO-5 Half-Height SAS Tape Drives

Storage environment

I IMPORTANT:

Always use the supplied label.

Figure 6: Attaching a label to media

1. label position

5.8 Storage environment

To prevent condensation and for long life, the cartridge should only be stored as
follows:

● Day-to-day storage (in plastic container): 16° C to 32° C (60° F to 90° F)

● Non-condensing relative humidity: 20% to 80% (storage)

● Wet bulb temperature should not exceed 26° C (79° F)

Tapes intended for long-term storage should be stored in the plastic containers,
at temperatures between 5° C and 23° C (41° F and 73° F) and 20% to 60%
relative humidity.

6 Troubleshooting

In this chapter:

● "General Procedure" on page 25

● "Understanding LED sequences" on page 27

● "Problems with cartridges" on page 32

6.1 General Procedure

If a problem occurs, the first step is to try to establish whether the problem lies
with the cartridge, the drive, the host computer and connections, or the way the
system is being operated.

Has the system just been installed?

There could be an installation problem:

1. Check through the information in the relevant installation chapter of this
guide.

2. Has the system booted? If not, check that all hard disks are correctly seated
in the hard disk bay and then check the cabling between the disks and the
SAS controller.

3. Has the system booted but the operating system has not seen the tape
drive? Check that the drive has power, the Ready LED should be illuminated.
If it is not, check that the power cord is connected correctly to the tape drive.
If the Ready LED is illuminated, check the cabling between the tape drive
and the SAS controller. Ensure that the HBA port to which the drive is
connected is enabled.

4. Are appropriate Tape drivers as well as supported application software
installed on the host?

5. Check the environmental conditions against the specified limits.

26 LTO-5 Half-Height SAS Tape Drives

General Procedure

Are you using new cartridges or a different brand of cartridge? Have you
been using the particular cartridge for a very long time?

The problem could lie with the cartridge:

1. Check through the media chapter on "Use the correct media" on page 17.

2. Check that you are using an LTO cartridge. Compatible media can be
recognized by the logo, which is the same as the logo on the front of your
drive.

3. Use the correct media type:

4. Has the cartridge been write-protected, see "Write protecting cartridges" on

page 19?

5. Clean the tape heads with the cleaning cartridge, see "Cleaning cartridges"

on page 17. Make sure you are using the Ultrium Universal cleaning

cartridge.

6. If the Tape LED is flashing, the cartridge is probably faulty. Try using a
different cartridge.

7. Try the operation again.

8. If the problem still occurs and you have not yet replaced the cartridge, try
using a different cartridge.

9. If the problem is still there, the problem probably lies with the drive or the
host computer.

Has the drive been moved recently? Have any cables been disconnected
and reconnected? Has the environment changed—unusually hot, cold,
damp or dry? Has there been dust or dirt near the drive. Have reasonable
precautions against static been taken?

The problem could lie with the drive or the environment:

1. Check the cables and connectors.

2. Clean the tape heads with the cleaning cartridge.

3. If the problem persists, check the environmental conditions against the
specified limits. Perhaps move the drive to a more suitable site.

LTO-5 Half-Height SAS Tape Drives 27

Understanding LED sequences

Has a new operating system been installed in the host computer? Has
new backup software been installed?

The problem could lie with the host or the software. Consult the computer's
operating manuals, the software manual, or seek help from a service engineer.

Reload the cartridge. If the Tape
LED still flashes or starts flashing
during the next backup, load a new
or known good cartridge.

If the Tape LED is now off, discard
the 'suspect' tape cartridge. If it is
still on, call for service.

6.2.1 Encryption LED

The encryption LED may be blue or amber, as described in the following table.
The state of the other LEDs depends upon the activity, as described below.

NOTE:

The Encryption LED only functions if you are using backup software that
supports hardware encryption and this feature is enabled in the backup
application. See the software manual for the backup application.

Encryption troubleshooting

● Ensure that you are using an LTO-5 tape drive and LTO Ultrium 5 or LTO

Ultrium 4 media.

● Ensure that your software supports hardware encryption. It may be

necessary to update the software. Consult your software vendor for more
information.

● Ensure that the correct key or pass phrase has been entered.

Encryption LED
(Blue or Amber)

State

On At power on

Off The drive is idle and there is no encryption key.

Off with Ready flashing
green

The tape drive is reading/writing unencrypted
data from another host or unloading a
cartridge.

On (solid blue) The drive is idle but the encryption key is

loaded. The drive is ready to read/write
encrypted data.

On (solid blue) with Ready
flashing green

The drive is reading/writing encrypted data.

Alternate flashing, blue and
amber

There is an encryption related error. This is
cleared after unload executes or successful
encryption/decryption resumes.

6.3 Problems with cartridges

If you experience any problems using cartridges, check:

● The cartridge case is intact and that it contains no splits, cracks or damage.

● The cartridge has been stored at the correct temperature and humidity. This

prevents condensation. See the insert included with the tape cartridge for
storage conditions.

● The write-protect switch is fully operational. It should move from side to side

with a positive click.

6.3.1 The cartridge is jammed

If the cartridge is jammed or the backup application is unable to eject it, you can
force eject the cartridge.

1. Attempt a drive unload/eject operation from the backup software.

Many backup applications will issue a Prevent Media Removal (PMR)
command to the drive robot in an attempt to prevent human interference
during a backup job. If this occurs, the software that issued the PMR must
be used to load and unload tapes.

2. Shut down backup software and, if in a Windows environment, stop
removable storage services.

3. Press the Eject button on the front of the tape drive.

Sometimes it is necessary to use the Eject button instead of software to
unload a tape because software can lose communication with the product or
a rogue application can prevent the software from unloading the tape.

I IMPORTANT:

This can take several minutes in many cases. Ensure that drive
activity has stopped before continuing on (waiting 10 minutes is a
good rule of thumb). It is important that you allow sufficient time for
the drive to complete rewinding the cartridge. If you interrupt it, you
may damage the media or the tape drive.

4. Power down the server.

5. Disconnect the data cable.

6. After at least 15 seconds, power the drive back up and wait till the drive is
idle/ready.

V CAUTION:

Use care when disconnecting data cables to ensure that connectors
are not reversed, pins

are not bent, and so on.

I IMPORTANT:

Powering up with a cartridge in the drive can take several minutes. It
is important that you allow sufficient time for the drive to complete
rewinding the cartridge. If you interrupt it, you may damage the media
or the tape drive.

7. Ensure that drive activity has stopped (waiting 10 minutes after power up is
a good rule of thumb). Push the Eject button.

This step attempts to overcome unload issues due to the drive being in an
abnormal state or because Prevent Media Removal has been incorrectly left
on after being set by a rogue application.

8. Initiate a force eject or emergency unload operation by pressing and holding
the Eject button for 15 seconds. This step causes the drive to try everything
possible to unload the tape.

V CAUTION:

You may lose data if you force eject a cartridge that is in the middle of
a backup. The tape may also become unreadable because an EOD
(End of Data) mark may not be properly written.

9. If the cartridge is still jammed, the tape drive has failed. Please contact
Fujitsu Customer Support.

Problems with cartridges

6.3.2 The drive will not accept the cartridge (or ejects it
immediately)

The cartridge may have been damaged, for example dropped, or the drive may
have a fault. If it is a cleaning cartridge, it has probably expired and should be
discarded immediately. For data cartridges:

1. Check that the drive has power (the power cord is properly connected and

the Ready LED is on).

2. Check that you are using the correct media. Use only LTO media.

3. Make sure that you have loaded the cartridge with the correct orientation

(see "Loading a cartridge" on page 13).

4. Check for damage to your media and discard it, if it is damaged.

5. Use a new or known, good piece of media and see if it loads. If it does, the

original cartridge is faulty and should be discarded.
