2Feature block switch (on the underside of the drive)
3.4SAS interface
The drive has a Gbps SAS (Serial Attached SCSI) host interface.
A drive with a SAS (Serial Attached SCSI) interface can be linked directly to
controllers. SAS is a performance improvement over traditional SCSI because
SAS enables multiple devices (up to 128) of different sizes and types to be
connected simultaneously with thinner and longer cables; its full-duplex signal
transmission supports 6.0 Gb/s. SAS drives will auto-negotiate speed. There
are no configurable topologies thus no setup is required for SAS interface.

Introduction
3.5Cartridge compatibility
The drive supports the following data cartridges:
–Ultrium-6 data cartridge at 2.5:1 compression (Read/Write)
–Ultrium-5 data cartridge at 2:1 compression (Read/Write)
–Ultrium-4 data cartridge at 2:1 compression (Read only)
I Ultrium-1, Ultrium-2, and Ultrium-3 data cartridges are not supported.
3.6Backup 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
3.7LTO-6 tape drives and encryption
The LTO-6 tape drive include 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-6
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
–Encryption is possible on LTO-4, LTO-5, and LTO-6 media.
–The LTO-4 data cartridge is read only on LTO-6 tape drive.
LTO-6 Half-Height SAS Tape Drive 15
Introduction
3.7.1When 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.
I 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.
3.7.2How 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.
3.7.3What 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 WARNIN G!
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.
Hardware encryption can be used with or without compression and without
speed or capacity impact.
16LTO-6 Half-Height SAS Tape Drive
Introduction
3.7.5Does the tape drive encrypt media in an earlier LTO
format?
Encryption is supported only on LTO Ultrium-6 media, LTO Ultrium-5 media, and
LTO Ultrium-4 media.
Encrypted LTO Ultrium-6, LTO Ultrium-5 and LTO Ultrium-4 tapes can be read
on any compatible LTO tape drive that supports hardware encryption. (LTO-6
tape drives can read and write encrypted LTO Ultrium-6 media and LTO
Ultrium 5 media. LTO-6 tape drives can read encrypted LTO Ultrium-4 media.)
Hardware encryption is not supported on any earlier LTO media, such as LTO
Ultrium-3 media.
3.7.6Where 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-6 Half-Height SAS Tape Drive 17
Introduction
3.8LTO-6 tape drives and partitioning
The LTO-6 tape drive supports up to four tape partitions, when used with LTO
Ultrium-6 cartridges. Tape partitioning is not supported with WORM (W
ead Multiple) cartridges or with earlier generations of cartridge. It is not
R
supported on earlier-generation tape drives. If you insert a partitioned tape into
a tape drive that does not support partitioning, it will be ejected.
To check for the latest information about support for partitioning and any
required firmware upgrades, refer to the following web sites:
The feature switch is located on the rear panel of the tape drive. Refer to "Rear
panel of the SAS drive" on page 14 for the location of the switch. The switch
positions are labeled 1 through 8. The on and off positions are marked on the
switch. The default settings for the feature switches are all switches placed in
the “OFF” position. Do not change the default settings.
3.10Supported device drivers
Device drivers enable the drive to interact with a variety of servers. Current
drivers, firmware and tools can be found on:

4Installing the drive
Before starting this installation, read these instructions and compare them to the
drive installation instructions for your server.
4.1Avoiding drive damage
To avoid static electricity damage when handling the drive, use the following
precautions:
●Limit your movement. Movement can cause static electricity to build around
you.
●Always handle the drive carefully. Never touch exposed circuitry.
●Prevent others from touching the drive.
●Before unpacking and installing the drive into a server, touch its static-
protective packaging to an unpainted metal surface on the enclosure for at
least two seconds. This reduces static electricity in the packaging and your
body.
●When possible, remove the drive from its static-protective packaging and
install it directly into an enclosure without setting it down. When this is not
possible, place the drive’s packaging on a smooth, level surface and place
the drive on the packaging.
●Do not place the drive on the cover of the enclosure or on any other metal
surface.

information sheet or the documentation on the following web sites:
Operating the drive involves using the following front panel items:
●Single-character Display (SCD)
●SCD Dot
●Status Lights
●Unload Button
5.1Single-character Display (SCD)
The SCD (5 in "Front panel of drive" on page 13) presents a single-character
code for error conditions and informational messages:
"Error Codes and Messages" on page 44 lists the codes for error conditions and
informational messages. If multiple errors occur, the code with the highest
priority (represented by the lowest number) displays first. When the error is
corrected, the code with the next highest priority displays, and so on until no
errors remain.
The SCD is blank during normal operation.
5.2Status Lights
The Status Lights (2 and 4 in "Front panel of drive" on page 13) are light-emitting
diodes (LEDs) that provides information about the state of the drive. The Ready

5.5Removing a Tape Cartridge
To remove a tape cartridge:
1. Ensure that the drive is powered-on.
2. Press the Unload Button. The drive rewinds the tape and partially ejects the
cartridge. The Ready Light flashes green while the tape rewinds, then goes
out before the cartridge partially ejects.
3. After the cartridge partially ejects, grasp the cartridge and remove it.
Important: Always remove an ejected cartridge before reinserting.
Whenever you unload a tape cartridge, the drive writes any pertinent
information to the cartridge memory.
If reset occurs while a cartridge is loaded, the drive will slowly rewind the tape
and eject the cartridge. If a power cycle occurs while a cartridge is loaded, the
drive will slowly rewind the tape. The drive will not automatically eject the
cartridge.
The Ready light flashes and the SCD will be counting down from 9 to 0,
indicating the approximate cartridge rewinding status. Between the counts, the
SCD displays random segments while the tape is rewinding into the cartridge.
Push the Unload Button to eject the cartridge when the Ready light stops
flashing.

5.7Cleaning the Drive Head
Attention: When cleaning the drive head, use a LTO Ultrium Cleaning
Cartridge.
Clean the drive head whenever "C" displays on the Single-character Display
and the Fault status light is flashing amber once per second.
To clean the head, insert the cleaning cartridge into the tape load compartment
(see "Front panel of drive" on page 13). The drive performs the cleaning
automatically in less than three minutes then ejects the cartridge.
I The drive will automatically eject an expired cleaning cartridge.
An LTO Ultrium Cleaning Cartridge is valid for 50 uses.
5.8Cautions Concerning Backup
5.8.1Ejecting 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.
LTO-6 Half-Height SAS Tape Drive 31
Operating the Drive
5.8.2Data compression rate
This product has a data compression function included in the hardware.
Although the data compression rate is approximately 250%, 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.
5.8.3Backup 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
5.8.4Points 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.
32LTO-6 Half-Height SAS Tape Drive
Operating the Drive
5.9Diagnostic and Maintenance Functions
I Please note that Fujitsu does not support maintenance mode. If the drive
is in a maintenance mode, power cycle the server.
5.10Updating Firmware
Attention: When updating firmware, do not power-off the drive until the update
is complete, or the firmware may be lost.
Periodically check for updated levels of drive firmware by visiting the web at:
–http://ts.fujitsu.com/support/downloads
Search for “lto“ in fulltext search or search based on the server system under
industry standard server.
Use the universal cleaning cartridge. It may be used for up to 50 cleans.
6.3.2Data cartridges
LTO-6 tape drives use the LTO-6 tape cartridges referred to in chapter
"Cartridge Compatibility" on page 36. 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 cartridges in other format tape drives.
For optimum performance always use a data cartridge that matches 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.
6.3.3Cartridge 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.
LTO-6 Half-Height SAS Tape Drive 37
Using Ultrium Media
6.3.4Write protecting cartridges
V CAUTION!
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. The location of the write-protect tab is illustrated by figure 6.
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 Ultrium format cartridges. This will
destroy pre-recorded servo information and make the cartridge
unusable.
6.3.5Cleaning the tape drive
Perform magnetic head cleaning when the following occurs:
– Periodically (once every three months)
– When the drive requests to be cleaned.
You must use the Ultrium LTO Universal Cleaning cartridge with LTO 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 2 minutes or more).
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, it has expired.
6.3.6Handling 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).
LTO-6 Half-Height SAS Tape Drive 39
Using Ultrium Media
●Do not drop cartridges or handle them roughly.
●Stick labels onto the label area only.
●Do not bulk erase (or degauss) Ultrium format cartridges because this will
render them unusable.
●Attach the label at the location shown in the following figure.
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.

"5"Tape drive hardware problem. The drive determined that a tape
path or read/write error occurred. To prevent damage to the drive
or tape, the tape drive will not allow you to insert a cartridge if the
current cartridge was successfully ejected. The error code may
clear when you cycle power to the tape drive. If the problem
persists, contact your support partner.
"6"Tape drive or media error. The tape drive determined that an error
occurred, but it cannot isolate the error to faulty hardware or to the
tape cartridge. Ensure the tape cartridge is the correct media type:
●Ultrium-1, Ultrium-2, and Ultrium-3 tape cartridges are not
supported by the LTO-6 Tape Drive. If the Ultrium-1, Ultrium-2,
or Ultrium-3 cartridge is loaded, SCD is displayed as "J".
●Drive will not accept an expired Cleaning Cartridge.
●Drive will not write over existing datasets on a WORM cartridge.
Ensure you are appending datasets on WORM media rather
than attempting to write over existing datasets
If the tape cartridge is the correct media type, perform the following
action:
1. Clean the drive with the cleaning cartridge.
2. Retry the operation.
3. If the problem persists, contact your support partner.
The error code clears when you remove the tape cartridge.

"7"Media error. The tape drive determined an error occurred because
of a faulty tape cartridge or an invalid tape cartridge. Ensure the
tape cartridge is the correct media type:
●Ultrium-1, Ultrium-2, and Ultrium-3 tape cartridges are not
supported by the LTO-6 Tape Drive. If the LTO-1, LTO-2, or LTO3 cartridge is loaded, SCD is displayed as "J".
●Drive will not accept an expired Cleaning Cartridge.
●Drive will not write over existing datasets on a WORM cartridge.
Ensure you are appending datasets on WORM media rather
than attempting to write over existing datasets.
If the tape cartridge is the correct media type, try another tape
cartridge. If the problem occurs with multiple tape cartridges, use
the following procedure:
1. Clean the drive with the cleaning cartridge.
2. Retry the operation.
3. If the problem persists, retry the operation with a new or a
known good cartridge. If the operation succeeds, discard the
defective tape cartridge. If the problem persists also with the
new tape cartridge, the problem probably lies with the drive.
Contact your support partner.
The error code clears when you remove the tape cartridge.
"8"Interface problem. The tape drive determined that a failure
occurred in the tape drive’s hardware or in the host bus. Check the
cabeling between the tape drive and the SAS controller. If the
problem persists, contact your support partner.

"A"Degraded operation. The tape drive determined that a problem
occurred which degraded the operation of the tape drive, but it did
not restrict continued use. If the problem persists, determine
whether the problem is with the drive or the media.
I The drive is usable, though the Single-character Display
continues to indicate an error and the Fault status light
flashes amber. The error code may clear when you cycle
power to the tape drive.
To determine if the problem is with the drive hardware, or the tape
media, perform the following procedure:
3. If the problem persists, retry the operation with a new or a
known good cartridge. If the operation succeeds, discard the
defective tape cartridge. If the problem persists also with the
new tape cartridge, the problem probably lies with the drive.
Contact your support partner.
"C"The tape drive needs to be cleaned. Clean the tape drive. See
"Cleaning the Drive Head" on page 31.
The error code clears when you clean the tape drive.

"e"Encryption Error. Displayed when the drive detects an error
associated with a encryption operation. If the problem occurred
while the tape drive was writing data to, or reading data from, tape:
1. Check the host application to ensure the host application is
providing the correct encryption key.
●Retry the encryption operation after the host application
problems have been resolved.
2. Check the operation of the tape drive by power cycling the
server and running POST. See table 3 on page 28.
●Refer to the error code displayed on the SCD if the drive
reset and POST fails.
●Retry the encryption operation if the drive reset and POST
complete without errors.
3. Check the media.
●Ensure the correct media is being used. Data encryption is
supported with LTO Ultrium-4, Ultrium-5, and Ultrium-6 Data
Cartridges only.
●Retry the encryption operation with the tape cartridge in
another encryption enabled drive. Replace the media if the
problem repeats with the same tape cartridge in multiple
drives.
If the problem occurred while the tape drive was running POST or
diagnostics, replace the drive.
The error code clears with the first attempted write/read after the
encryption key is changed.

"P"Write operation to a write protected cartridge has been
attempted (this includes any attempt to overwrite a WORM
protected tape). Ensure the tape cartridge is the correct media type.
Writes to Ultrium-1, Ultrium-2, Ultrium-3, and Ultrium-4 tape
cartridges are not supported in the LTO-6 Tape Drive. If the tape
cartridge is the correct media type, check the write-protect switch on
the cartridge. The drive will not write to a write-protected cartridge.
The error code clears when you remove the tape cartridge.
"J"Incompatible media was used. The tape drive detected an
unsupported cartridge was loaded or the cartridge loaded has an
incompatible format. Ensure the tape cartridge is the correct media
type.See "Cartridge Compatibility" on page 36.
"u"Firmware update is in progress. The drive is in the prosess of
Mid-tape Recovery. Drive is recovering from power cycle with tape
in drive. The figure "8" is broken up with a countdown indicating
progress in ten’s percentage to completion (9,8,7,6,5,4,3,2,1).
Please wait until mid tape recovery ends.
