Chapter 1. Introduction
The IBM TotalStorage Linear Tape-Open (LTO) Ultrium 2 Tape Drive is a
high-performance, high-capacity data-storage device that is designed to backup and
restore Open Systems applications. The drive can be integrated into an enclosure,
such as a desktop unit, tape autoloader, or tape library. The Ultrium 2 Tape Drive
(called Generation 2) is the second-generation tape drive in the Ultrium series of
products. It is available as Model T400 with a Small Computer Systems Interface
(SCSI) or as Model T400F with a Fibre Channel interface.
The Ultrium 2 Tape Drive offers the following features:
v Native storage capacity of up to 200 GB per cartridge (400 GB assuming 2:1
LTO Data Compression)
v Native sustained data transfer rate of 35 MB per second (70 MB assuming 2:1
LTO Data Compression)

Cartridge Compatibility
The Ultrium 2 Tape Drive (Generation 2) uses the IBM TotalStorage LTO Ultrium
200 GB Data Cartridge and is compatible with the cartridges of its predecessor, the
IBM Ultrium Internal Tape Drive (called Generation 1). The Ultrium 2 Tape Drive
performs the following functions:
v Reads and writes Generation 2 cartridges to Generation 2 format
v Reads and writes Generation 1 cartridges to Generation 1 format
v Does not write Generation 2 cartridges to Generation 1 format
v Does not write Generation 1 cartridges to Generation 2 format
The Ultrium 2 Tape Drive reads tapes that have been written by other licensed
Ultrium 2 drives. It also writes to tapes that can be read by other licensed Ultrium 2
drives.
In addition to using the IBM TotalStorage LTO Ultrium Data Cartridge with up to 200
GB capacity, the Ultrium 2 Tape Drive also offers read/write capability for certified
LTO Ultrium tape cartridges.
Speed Matching and Channel Calibration
To improve system performance, the Ultrium 2 Tape Drive uses a technique called
speed matching to dynamically adjust its native (uncompressed) data rate to the
slower data rate of a server. With speed matching, the drive operates at one of five
speeds when reading or writing the Generation 2 cartridge format to achieve a
native data rate of 17.5, 21.9, 26.25, 30.63, or 35 MB per second (MB/s). If the
server’s net (compressed) data rate is between two of the preceding native data
rates, the drive calculates which of the two data rates at which to operate. (For
example, if the server transfers data at 60 MB/s on the host bus, at 2:1
compression its net data rate is 30 MB/s. The drive will then dynamically choose to
operate at a native data rate of 26.25 or 30.63 MB/s, whichever enables it to
successfully receive the greatest amount of compressed data over the network.)
Speed matching dramatically reduces backhitch, the condition that occurs when a
tape stops, reverses, and restarts motion. A backhitch is usually the result of a
mismatch between the data rates of the server and the drive.
System performance is further optimized by a feature called channel calibration, in
which the drive automatically customizes each read/write data channel to
compensate for variations in such things as the recording channel’s transfer
function, the media, and characteristics of the drive head.
Sleep Mode
To conserve energy when circuit functions are not needed for drive operation, the
Ultrium 2 Tape Drive features a power-management function that causes the drive’s
electronics to enter a low-power mode known as sleep mode. To enter sleep mode,
the drive must be inactive for a minimum of 15 minutes; to exit, the drive must
receive a command across the SCSI or Fibre Channel interface, a command across
the Library/Drive Interface (LDI or RS-422 interface), or a load or unload request.
When in sleep mode, the drive’s response time to commands that do not require
media motion increases by up to 10 microseconds. Commands that require media
motion may be delayed an additional 100 milliseconds because the tape must be
retensioned.

SCSI Attachment
To communicate with a server, the IBM TotalStorage LTO Ultrium 2 Tape Drive uses
the Ultra160 LVD SCSI interface.
Physical Characteristics of the SCSI Interface
The Ultrium 2 Tape Drive contains a high-density, 68-pin, D-shell receptacle
connector (HD68) for attachment to the server. The HD68 connector includes the
connectors for the SCSI signal, the SCSI ID, and the drive’s power. The drive
supports LVD SCSI cables with HD68 connectors.
Speed
The Ultra160 LVD SCSI interface is backward compatible with older SCSI
technology and is capable of data transmission at 160 MB/s. Ultra160 SCSI uses
the three management features of the Ultra3 SCSI standard that specifically affect
data transfer rate:
v Double transition clocking - a data-transfer technique that enables data rates
to double without increasing clock speed
v Domain validation - a procedure that detects and adjusts SCSI configuration
issues that might prevent interoperation between SCSI devices
v Cyclic redundancy check (CRC) - an error-checking technique
Because the cables, connectors, and terminators are the same for the Ultra160 and
Ultra2 SCSI interfaces, devices with those interfaces can be mixed on the same
bus and each device can operate at its fully rated speed.

Address Assignments
Each device on a SCSI bus must have a SCSI identifier (ID) that identifies it to the
server. When you install the Ultrium 2 Tape Drive, you can specify its SCSI ID in
one of three ways:
v By attaching jumpers to the SCSI ID connector
v By using your enclosure’s SCSI ID switch
v If you are installing the drive into a tape library, by setting the SCSI ID through
the LDI or RS-422 interface
Installing, Removing, or Resetting a Drive on an Active SCSI Bus
You can attach an Ultrium 2 Tape Drive to an active SCSI bus. However, the
preferred and safest method of adding, removing, or resetting a drive is to power-off
the system.
When adding, removing, or resetting a drive on an active SCSI bus, perform the
following steps:
1. Quiesce the drive. The drive to be added, removed, or reset must not be
involved in any bus activity.
2. Disconnect power to the drive.
3. Connect or disconnect the SCSI bus cables to or from the drive’s SCSI
connector. Ensure that the SCSI bus remains intact from the server (initiator) to
the terminator throughout the connection or disconnection process.
Note: Changing or moving the terminator disrupts the continuity of the SCSI
bus and interrupts any process on the bus.

Fibre Channel Attachment
Attention: A Class I laser assembly, in the optical transceiver, is
mounted on the Ultrium Fibre Channel electronics card. This laser
assembly is registered with the Department of Health and Human
Services and is in compliance with IEC825.
To communicate with a server, the Ultrium 2 Tape Drive has one Fibre Channel
interface (also called a port). In accordance with the standards of the American
National Standards Institute (ANSI), the port runs Fibre Channel Protocol (which
includes SCSI commands on the Fibre Channel) with ANSI-defined Fibre Channel
Tape Support. The method by which the drive and server communicate is
determined by the type of topology in which they reside and the type of connection
that you choose.
Supported Topologies
The Ultrium 2 Tape Drive can be attached in a two-node configuration, either
directly to a switch as a public device (switched fabric) or directly to a host bus
adapter (HBA) as a private device. It can do so in a Point-to-Point topology (through
an N_port or F_port) or Arbitrated Loop topology (through an L_port or FL_port).
Unless you set the drive to force an explicit configuration (by using the FC
L_port or an N_port when it boots. The type of port to which it configures depends
on whether the drive recognizes the connection as a loop or a point-to-point
connection:
v An L_port supports a Fibre Channel Arbitrated Loop connection to an NL_port or
FL_port.
v An N_port supports direct connection to another N_port or to an F_port (for
example, a director-class switch) in a point-to-point topology.
Regardless of the port to which you connect the drive, it automatically configures to
a public device (through an F_port or FL_port to a switch) or to a private device
(through an N_port or L_port by using direct attachment to a server).
Channel server connections that are available, and the port (NL, N, FL, or F)
through which communication must occur.

Speed
The Ultrium 2 Tape Drive’s Fibre Channel interface facilitates data at 2 Gb/s (200
MB/s). It automatically negotiates to a rate of 1 Gb/s (100 MB/s) if the system or
switch to which it connects does not support the 2-Gb rate (if this is the case, you
may experience performance degradation). You can force the drive to an explicit
speed by placing jumpers on the Fibre Channel (FC) configuration/status connector.
Address Assignments
Each device on a Fibre Channel loop must have a Loop Identifier (LID) and a
corresponding Arbitrated Loop Physical Address (AL_PA) to communicate with other
devices in the topology. The AL_PA identifies the device on the loop. (LIDs and their
You can set an AL_PA by using one of two methods known as soft addressing or
hard addressing.
Soft addressing allows the drive to dynamically arbitrate the AL_PA with other Fibre
Channel devices on the loop. Hard addressing allows you to choose the LID, which
determines the corresponding AL_PA. The higher the AL_PA, the lower the priority
of the device.
Generally, servers (initiators) require that devices use hard addressing; they do not
support soft addressing. When setting addresses, assign the lowest AL_PA (and
thus the highest priority) to the server; assign the highest AL_PA (and thus the
lowest priority) to the drive.
To set soft or hard addressing, you must place jumpers on designated pins in the

World Wide Names
Each Ultrium 2 Tape Drive has an 8-byte World Wide Node Name and an 8-byte
World Wide Port Name that is assigned by IBM Manufacturing. The World Wide
Node Name identifies the drive’s SCSI logical unit; the World Wide Port Name
identifies the physical port on the drive. An enclosure queries the World Wide
Names through the LDI or RS-422 interface; a server queries the Names through
the Fibre Channel interface. The Ultrium 2 Tape Drive reports the World Wide
Names to switches. You can use the World Wide Node Name or Wide Node Port
Name to uniquely identify the drive on a SAN.
When your Ultrium 2 Tape Drive is installed in a tape library, you can change the
World Wide Node Name and World Wide Port Name through the LDI or RS-422
interface. For instructions, refer to the documentation for your tape library.
Physical Characteristics of the Fibre Channel Interface
The Ultrium 2 Tape Drive attaches to Open Systems servers by using short-wave,
multimode fiber optic cables. All cables feature LC-duplex connectors and are
designated as 50/125 (50 refers to the diameter of the optical fiber and 125 refers
to the diameter of the cable; both are measured in micrometers).
Installing, Removing, or Resetting a Drive on an Active Fibre Channel
A Fibre Channel network supports dynamic drive attachment. When adding,
removing, or resetting a drive on an active server or SAN, perform the following
steps:
1. Quiesce the drive. The drive to be added, removed, or reset must not be
involved in activity.
2. Connect or disconnect the Fibre Channel cables to or from the drive.

Chapter 3. Installing the Tape Drive
Attention:
To avoid static electricity damage when you handle the IBM TotalStorage LTO
Ultrium 2 Tape Drive, use the following precautions:
v Limit your movement. Movement can cause static electricity to build around
you.
v Always handle the Ultrium 2 Tape Drive carefully. Never touch exposed
circuitry.
v Prevent others from touching the Ultrium 2 Tape Drive.
v Before you unpack and install the Ultrium 2 Tape Drive into an enclosure,
touch its static-protective packaging to an unpainted metal surface on the
enclosure for at least 2 seconds. This reduces static electricity in the
packaging and your body.
v When possible, remove the Ultrium 2 Tape Drive from its static-protective
packaging and install it directly into an enclosure without setting it down.
When this is not possible, place the tape drive’s packaging on a smooth,
level surface and place the tape drive on the packaging.
v Do not place the Ultrium 2 Tape Drive on the cover of the enclosure or on
any other metal surface.
The steps that follow describe how to install the Ultrium 2 Tape Drive into an
enclosure.
Note: Depending on the type of enclosure, installation procedures may vary. Before
starting this installation, read these instructions and compare them to the
drive installation instructions for your enclosure.

Step 1. Unpack the Drive
Unpack the Ultrium 2 Tape Drive and store the packaging. You may need the
packaging if you return the unit for service.
Attention::
Acclimation time is required if the temperature of the drive when unpacked is
different than the temperature of its operating environment (measured at the front of
time is 4 hours after the drive has been unpacked or 1 hour after any condensation
that you can see has evaporated, whichever is greater. When acclimatizing the
drive, apply the following measures:
v If the drive is colder than its operating environment and the air contains sufficient
humidity, condensation may occur in the drive and damage it. When the drive
has warmed to the operating temperature range (greater than 10°C or 50°F) and
no danger of condensation is present (the air is dry), warm the drive more quickly
by powering it on for 30 minutes. Use a diagnostic tape to test the drive before
inserting a tape that contains data.
v If the drive is hotter than its operating environment, the tape can stick to the drive
head. When the drive has cooled to the operating temperature range (less than
40°C or 104°F), cool the drive more quickly by applying airflow for 30 minutes.
Power-on the drive and use a diagnostic tape to test it before inserting a tape
that contains data.
If you are uncertain about whether the temperature of the drive is within the
recommended operating range or the humidity is sufficient to cause condensation,
acclimate the drive for the full 4 hours.
Figure 4. Measuring the temperature of the operating environment. The temperature is
measured at the front of the bezel, near the air intake area.
Step 2. Remove Power from the Enclosure
__ 1. Power-off the enclosure (or the unit that provides power to the drive)
__ 2. Disconnect the power cord from both the electrical outlet and the enclosure.

Step 3. Set the SCSI ID or Arbitrated Loop Physical Address
Perform one of the following steps:

v If you are installing an Ultrium 2 Tape Drive that uses a Fibre Channel interface
(Model T400F), you must set the drive’s Arbitrated Loop Physical Address
Setting the SCSI ID (SCSI Drive Only)
You can set the SCSI ID in one of three ways:
v By placing jumpers on the SCSI ID connector
v By using a SCSI ID switch that is connected to the SCSI ID connector
v By issuing a command from the library to set the SCSI ID through the drive’s LDI
interface
The sections that follow describe each method of setting the SCSI ID.
Setting the SCSI ID with Jumpers
You can set the SCSI ID on the Ultrium 2 Tape Drive by installing 2-mm jumpers on
may come set to a default SCSI configuration, with jumpers already installed. To
change the default SCSI configuration, contact your sales or or technical support
representative. You can change the SCSI ID by rearranging, adding, or removing
jumpers.
To set the SCSI ID:
__ 2. Before attaching the SCSI bus cable to the server, decide the SCSI ID
number that you want. Make sure that the ID is not being used by another
device.
place jumpers on the connector pins as shown (use a pair of needle-nose
pliers to connect the jumpers to the pins that are shaded).
Note: If you set the SCSI ID to 15, the drive will not necessarily be set to
that ID; instead, the drive will expect to receive the SCSI ID through a
command over its LDI interface.

Setting the SCSI ID with a SCSI ID Switch
If your enclosure uses a SCSI ID switch (rather than jumpers), connect the switch
are pre-installed, be sure to remove them before connecting the switch. The SCSI
ID switch must be compatible with the drive’s SCSI ID connector and must make an
electrical connection between the same pins as the jumpers to achieve the same
corresponding SCSI ID.
Setting the SCSI ID Through the LDI Interface
If you are installing the Ultrium 2 Tape Drive into a tape library, you can issue a
command from the library to set the drive’s SCSI ID through the LDI interface.
its SCSI ID through the LDI interface, the drive does not respond to SCSI
commands until it receives a Set Configuration command through the interface.
Supplying TERMPOWER (SCSI Drive Only)
To supply TERMPOWER to the bus, locate one of the five jumpers shipped with the
Ultrium 2 Tape Drive and place it on the SCSI ID connector as shown in the
following figure. Place the jumper on the pins that are shaded.
Note that you must provide SCSI termination externally to the Ultrium 2 Tape Drive.

Setting the Arbitrated Loop Physical Address (Fibre Channel Drive
Only)
Each device on a Fibre Channel loop must have an Arbitrated Loop Physical
Address (AL_PA) to communicate. The AL_PA identifies the device on the loop. To
set the Ultrium 2 Tape Drive’s AL_PA, you must place jumpers on specific pins in
the drive’s loop identifier (LID)/status connector. The placement of the jumpers
indicates whether you want to choose the LID yourself (each LID corresponds to a
specific AL_PA) or whether you want the drive to choose the AL_PA by arbitrating it
with other devices on the loop. Valid LIDs and their corresponding AL_PAs are
provided in this section.
Note: A Loop ID is part of a contiguous range of values; valid AL_PA values are
not in a contiguous range.
In addition to establishing the AL_PA, by moving Feature Switch 3 on the drive to
ON or off you can set the drive so that it provides one of the following functions:
v Status about the Fibre Channel loop (through the use of external indicators in an
enclosure)
v Additional LIDs
The sections that follow describe how to select the AL_PA. They also describe how
to set Feature Switch 3 so that the drive gives status about the loop or provides
additional LIDs.
Chapter 3. Installing 19
Download from Www.Somanuals.com. All Manuals Search And Download.
Setting the Loop ID to Provide Status About the Loop
the LID/status connector ꢀ2ꢁ has the following definition:
v Pins 1, 2, 3, 4, 7, and 8 are inputs and are used to set the LID.
v Pins 5 and 6 are used as outputs:
– Pin 5 has three states: off (ground), on (3.3 V), and alternating (between off
and on). Pin 5 will be off if the drive does not detect light on the Fibre
Channel connector, if (while communicating as an L_port) the drive does not
complete the Loop Initialization Protocol (LIP), or if (while communicating as
an N_port) the drive does not complete logging in to the host or switch. Pin 5
will be on if the drive detects light, successfully completes the LIP process, or
logs in to another port. After the drive has completed the LIP process, the pin
will be alternating when the drive is receiving SCSI commands, and the pin
will be on when the drive is not receiving SCSI commands.
– Pin 6 indicates that the drive detects light. If pin 6 is on but pin 5 is off, this
could indicate communication problems across the fiber cable.
– If the drive is installed in an enclosure, pins 5 and 6 may be used to support
external indicators, such as light-emitting diodes (LEDs), on the enclosure.
Note: If indicators are used on an enclosure, the drive does not report error
codes 8 and F (Fibre Channel problems) to the single-character
display. Instead, pins 5 and 6 signal to the indicators that there is a
problem.
v Pin 9 is ground.
Figure 6. Setting the Loop ID and the AL_PA. The feature switches are located on the bottom
of the drive.
To set the AL_PA:
its corresponding LID.
By using hard addressing, you can specify one of 62 valid AL_PAs for the
drive. If you place jumpers on the four top and bottom pins on the right (a
total of eight pins), the drive gets the AL_PA from a field in its vital product
data (VPD). (A tape library can set the AL_PA in the VPD through the LDI
interface.) If you do not place jumpers on any pins, the drive uses soft
addressing to determine the AL_PA.

Setting the Loop ID to Provide Additional Loop IDs
v Pins 1 through 7 are used to set the LID.
v Pin 8 overrides pins 1 through 7. If you place a jumper on pin 8, the drive uses
its vital product data (VPD) to set the AL_PA. A tape library can set the AL_PA in
VPD through the LDI interface.
v Pin 9 is ground.
Note: Feature Switch 3 does not support LEDs on an enclosure. Therefore, when
Feature Switch 3 is set to ON, the drive can report Fibre Channel problems
(error codes 8 and F) on the single-character display, but not by using the
enclosure’s external indicators.
To set the AL_PA:
corresponding LID.

v Obtaining the new firmware image and downloading it to the drive through the
SCSI or Fibre Channel interface
v Obtaining the new firmware image and downloading it to the drive through the
LDI or RS-422 interface
v Loading the firmware from a field microcode replacement (FMR) tape cartridge
For instructions about how to obtain a new firmware image or FMR tape, visit the
preceding web site. To update the firmware, refer to the following sections.
Updating Firmware through the SCSI or Fibre Channel Interface
Attention: SCSI drives and Fibre Channel drives require different firmware
images.
When you update the tape drive’s firmware by using the SCSI or Fibre Channel
interface, the procedure varies, depending on whether your server uses an IBM
tape device driver or a non-IBM tape device driver (such as a driver from Sun,
Hewlett-Packard, or Microsoft).
For instructions about updating firmware from a server that uses an IBM tape
device driver, refer to the IBM Ultrium Device Drivers Installation and User’s Guide.
To update firmware from a server that uses a non-IBM tape device driver, refer to
the documentation for that device driver.
Updating Firmware through the Library/Drive Interface
The Ultrium 2 Tape Drive includes a firmware update feature that allows a tape
library to download firmware to the drive by using the Library/Drive Interface (LDI)
while the drive performs normal host operations on logical unit number (LUN) 0 of
the SCSI Protocol Interface. The update typically takes 63 seconds and a maximum
of 140 seconds. To activate the new firmware, cycle power to the drive, or unload
the drive and issue a Power-on Reset command. The command may be received
by the SCSI interface or the LDI (RS-422) interface.
Note: If a Power-on Reset command is received while a cartridge is loaded in the
drive, the drive will respond with a Check Condition. It will not activate the
new code level until you cycle power, or until you receive a Power-on Reset
command when the drive does not contain a cartridge.

In addition to using LTO Ultrium 2 Tape Cartridges with up to 200 GB capacity, the
tape drive reads and writes to certified LTO Ultrium Tape Cartridges that have
capacities of 100, 50, 30, and 10 GB. If you want to control the capacity of the
cartridge (for example, if you want to limit the capacity to obtain a faster seek time)
you can do so by issuing the SCSI command SET CAPACITY. For information
about this command, refer to the IBM TotalStorage LTO Ultrium Tape Drive SCSI
Reference.
To ensure that your tape drive conforms to IBM’s specifications for reliability, use
only IBM TotalStorage LTO Ultrium Tape Cartridges. You may use other
LTO-certified data cartridges, but they may not meet the standards of reliability that
are established by IBM. The IBM TotalStorage LTO Ultrium 200 GB Data Cartridge
cannot be interchanged with the media used in other IBM non-LTO Ultrium tape
products.
Data Cartridge
The IBM TotalStorage LTO Ultrium 200 GB Data Cartridge contains 1/2-inch,
dual-coat, metal-particle tape that has a native data capacity of 200 GB (400 GB at
2:1 compression). When processing the tape, the IBM TotalStorage LTO Ultrium 2
Tape Drive uses a linear, serpentine recording format, and reads and writes data on
512 tracks, eight tracks at a time. The first set of eight tracks is written from near
the beginning of the tape to near the end of the tape. The head then repositions to
the next set of eight tracks for the return pass. This process continues until all
tracks are written and the tape is full, or until all data is written.
The IBM TotalStorage LTO Ultrium 200 GB Data Cartridge includes a Linear
contains information about the cartridge and the tape (such as the name of the
manufacturer that created the tape), as well as statistical information about the
cartridge’s use. Whenever you unload a tape cartridge, the tape drive writes any
pertinent information to the cartridge memory. The storage capacity of the LTO-CM
is 4096 bytes.
The cartridge door ꢀ2ꢁ protects the tape from contamination when the cartridge is
out of the drive. Behind the door, the tape is attached to a leader pin ꢀ3ꢁ. When
you insert the cartridge into the drive, a threading mechanism pulls the pin (and
tape) out of the cartridge, across the drive head, and onto a non-removable takeup
reel. The head can then read or write data from or to the tape.
The write-protect switch ꢀ4ꢁ prevents data from being written to the tape cartridge.
The label area ꢀ5ꢁ provides a location for you to place a label. Affix only a bar code
label. When affixing a label, place it only in the recessed label area. A label that
extends outside of the recessed area can cause loading problems in the drive. The
insertion guide ꢀ6ꢁ is a large, notched area that prevents you from inserting the
cartridge incorrectly.
You can order tape cartridges with the bar code labels included, or you can order
The IBM TotalStorage LTO Ultrium 200 GB Data Cartridge has a nominal cartridge
life of 5000 load and unload cycles. The Generation 2 cartridge is purple; the

Cleaning Cartridges
The Ultrium 2 Tape Drive is compatible with the IBM LTO Ultrium Cleaning
Cartridge (part number 08L9124) and the IBM TotalStorage Cleaning Cartridge
(Ultrium LTO 2) (part number 35L2086).
The IBM TotalStorage Cleaning Cartridge functions with Ultrium-format tape drives
that are produced by compliance-verified manufacturers. The cartridge lets you buy
and use a single cleaning cartridge for all of your tape drives, rather than spend
time and money to support several different cleaning cartridges.
The IBM TotalStorage Cleaning Cartridge (Ultrium LTO 2) is downward-compatible
with the Ultrium Internal Tape Drive (Generation 1). To enable your Generation 1
drive to use the cartridge, simply download and install the latest drive firmware (for
The drive itself determines when a head needs to be cleaned. It alerts you by

Provide Training
v Post procedures that describe proper media handling in places where people
gather.
v Ensure that anyone who handles tape has been properly trained in handling and
shipping procedures. This includes operators, users, programmers, archival
services, and shipping personnel.
v Ensure that any service or contract personnel who perform archiving are properly
trained in media-handling procedures.
v Include media-handling procedures as part of any services contract.
v Define and make personnel aware of data recovery procedures.
Ensure Proper Packaging
v When you ship a cartridge, ship it in its original or better packaging.
v Always ship or store a cartridge in a jewel case.
v Use only a recommended shipping container that securely holds the cartridge in
its jewel case during transportation. Ultrium Turtlecases (by Perm-A-Store) have
Figure 13. Tape cartridges in a Turtlecase
v Never ship a cartridge in a commercial shipping envelope. Always place it in a
box or package.
v If you ship the cartridge in a cardboard box or a box of a sturdy material, ensure
the following:
– Place the cartridge in polyethylene plastic wrap or bags to protect it from dust,
moisture, and other contaminants.
– Pack the cartridge snugly; do not allow it to move around.
– Double-box the cartridge (place it inside a box, then place that box inside the

Provide Proper Acclimation and Environmental Conditions
v Before you use a cartridge, let it acclimate to the normal operating environment
for 1 hour. If you see condensation on the cartridge, wait an additional hour.
v Ensure that all surfaces of a cartridge are dry before inserting it.
v Do not expose the cartridge to moisture or direct sunlight.
v Do not expose recorded or blank cartridges to stray magnetic fields of greater
than 100 oersteds (for example, terminals, motors, video equipment, X-ray
equipment, or fields that exist near high-current cables or power supplies). Such
exposure can cause the loss of recorded data or make the blank cartridge
unusable.
Perform a Thorough Inspection
After purchasing a cartridge and before using it, perform the following steps:
v Inspect the cartridge’s packaging to determine potential rough handling.
v When inspecting a cartridge, open only the cartridge door. Do not open any other
part of the cartridge case. The upper and lower parts of the case are held
together with screws; separating them destroys the usefulness of the cartridge.
v Inspect the cartridge for damage before using or storing it.
v Inspect the rear of the cartridge (the part that you load first into the tape load
compartment) and ensure that there are no gaps in the seam of the cartridge

Attention:
v Use only the IBM Leader Pin Reattachment Kit to reattach the leader pin to the
tape. Other methods of reattaching the pin will damage the tape, the drive, or
both.
v Use this procedure on your tape cartridge only when the leader pin detaches
from the magnetic tape and you must copy the cartridge’s data onto another
cartridge. Destroy the damaged cartridge after you copy the data. This procedure
may affect the performance of the leader pin during threading and unloading
operations.

Environmental and Shipping Specifications for Tape Cartridges
Before you use a tape cartridge, acclimate it to the operating environment for 24
hours or the time necessary to prevent condensation in the drive (the time will vary,
depending on the environmental extremes to which the drive was exposed).
The best storage container for the cartridges (until they are opened) is the original
shipping container. The plastic wrapping prevents dirt from accumulating on the
cartridges and partially protects them from humidity changes.
When you ship a cartridge, place it in its jewel case or in a sealed, moisture-proof
bag to protect it from moisture, contaminants, and physical damage. Ship the
cartridge in a shipping container that has enough packing material to cushion the
cartridge and prevent it from moving within the container.

Disposing of Tape Cartridges
Under the current rules of the U.S. Environmental Protection Agency (EPA),
regulation 40CFR261, the LTO Ultrium Tape Cartridge is classified as
non-hazardous waste. As such, it may be disposed of in the same way as normal
office trash. These regulations are amended from time to time, and you should
review them at the time of disposal.
If your local, state, country (non-U.S.A.), or regional regulations are more restrictive
than EPA 40CFR261, you must review them before you dispose of a cartridge.
Contact your account representative for information about the materials that are in
the cartridge.
If a tape cartridge must be disposed of in a secure manner, you can erase the data
on the cartridge by using a high-energy AC degausser (use a minimum of 1200
oersted peak field over the entire space that the cartridge occupies). Degaussing
makes the cartridge unusable.
If you burn the cartridge and tape, ensure that the incineration complies with all
applicable regulations.

Using Sense Data
When a tape drive encounters an error, it makes sense data available. You can use
IBM device drivers to examine the sense data and determine errors. Instructions for
downloading, installing, and properly configuring the IBM device drivers are
available in the IBM Ultrium Device Drivers Installation and User’s Guide. The IBM
device drivers may conflict with some commercial software applications unless
properly configured. To avoid conflicts on Windows operating systems, refer to your
device driver’s procedures for setting the driver to manual startup mode. For
applications that use Open Systems device drivers that are provided by IBM (for
example, AIX, Linux, Sun Solaris, HP-UX, Windows/NT, and Windows 2000), the
IBM Ultrium Device Drivers Installation and User’s Guide contains information about
how to obtain sense data after an error has occurred.
If your application uses other device drivers, see the appropriate documentation for
those drivers to obtain the sense data.
Raw sense data (as returned from the Ultrium 2 Tape Drive) is documented in the
IBM TotalStorage LTO Ultrium Tape Drive SCSI Reference.
In addition to device drivers, other methods exist for obtaining sense data and error
information. The sections that follow describe alternatives for gathering such
information from the IBM AS/400, Eserver iSeries, RS/6000, and Eserver
pSeries servers.
Obtaining Error Information from the AS/400 or iSeries with RISC
Processor
For OS/400, sense data is provided by the System Service Tools application. To
obtain error information from the AS/400 or iSeries by using the tool:
1. On the command entry line of the AS/400 Main Menu, type STRSST (Start
System Service Tools) and press Enter.
2. Select Start a service tool.
3. Select Product activity log.
4. Select Analyze log.
5. On the Select System Data menu, select the Magnetic media option then
specify the time period for searching the error log.
6. On the Select Analysis Report Options menu, specify a Device selection of 3580
and press Enter. Leave all other options at their default values.
7. On the Log Analysis Report menu, select the Display report option to display the

Obtaining a Drive Dump
You can obtain a drive dump by selecting a function code on the IBM TotalStorage
LTO Ultrium 2 Tape Drive or by using a device driver utility (or a system tool) on the
server. The sections that follow describe each method.
Using the Drive to Obtain a Dump
To obtain a drive dump directly from the IBM TotalStorage LTO Ultrium 2 Tape
Drive:
1. Make sure that no cartridge is in the drive.
2. Within a 1.5-second interval, press the unload button three times. The status
light becomes solid amber, which means that the drive is in maintenance mode.
3. Press the unload button once per 1.5 seconds until 5 appears in the
single-character display.
4. To select the function, press and hold the unload button for 3 seconds. After you
release the button, C flashes. Within 60 seconds, insert a scratch data cartridge
that is not write-protected. After you insert the cartridge, 5 flashes and the drive
writes the dump data to the scratch tape. When the function is complete, the
drive rewinds and unloads the tape.
5. Insert the tape into a drive.
6. From the server, issue the SCSI READ command to read the dump from the
tape to a file or electronic image (you may need to issue the command several
times to read the complete dump).
7. To determine where to send the file for analysis, contact your OEM Product
Application Engineer (PAE).
Using a Device Driver Utility to Obtain a Dump
To obtain a drive dump by using a device driver utility, determine whether your
server is installed with a utility that can read files from the server’s memory. If it is,
use that utility to obtain the drive dump.
For information about using IBM’s utility programs to obtain drive dumps, see the
IBM Ultrium Device Drivers Installation and User’s Guide.
To determine where to send a file that contains a drive dump to be analyzed,
contact your OEM Product Application Engineer (PAE).

Resolving Problems Reported by the Server
The procedure for fixing SCSI bus or Fibre Channel errors varies, depending on
whether the error is consistent or intermittent, and whether your configuration
contains single or multiple Ultrium 2 Tape Drives. The sections that follow describe
how to fix each type of error.
Fixing SCSI Bus Errors
Note: If you are using a Storage Area Network (SAN) Data Gateway to convert a
drive with a SCSI interface to a Fibre Channel interface, ensure that the
problem is occurring between the SAN Data Gateway and the drive by
running the SCSI wrap test on the drive and running the SCSI loopback test
on the SAN Data Gateway. (To run the SCSI wrap test, see Function Code 6
about that test in the IBM Storage Area Network Gateway Module Setup,
Operator, and Service Guide.) If you are using a Fibre Channel drive and are
Fixing a Consistent Error with a Single Drive on a SCSI Bus
1. Ensure that the power is on to the Ultrium 2 Tape Drive.
2. Ensure that the tape drive’s SCSI address is the same as the SCSI address
assigned by the server.
v If the test runs successfully, replace the SCSI terminator first, then the SCSI
cable and the interposer (if installed). Repeat the operation that caused the
error. If you replaced the SCSI terminator or SCSI cable and the problem
persists, the fault is with the server’s hardware or software. To isolate the
cause of the failure, refer to the server’s service documentation.
Fixing a Consistent Error with Multiple Drives on a SCSI Bus
When a consistent error occurs in a configuration that has multiple tape drives on
the SCSI bus, you must determine if the problem exists with more than one tape
drive. If the problem is with all of the devices on the SCSI bus, the bus is stuck in a
SCSI phase and cannot change to another phase or the SCSI cable from the server
to the first device is defective.
1. Ensure that the SCSI cable from the server to the first device is connected.
2. Disconnect all but the first tape drive on the SCSI bus. Move the terminator to
the first SCSI device.
3. Run a device driver utility (such as IBM’s ntutil or tapeutil) to determine whether
the error will occur.
v If the error occurs, run the SCSI wrap test on the first tape drive (see
– If the test runs successfully, replace the SCSI terminator first, then the
SCSI cable and the interposer (if installed) to the first tape drive. Repeat
the operation that caused the error. If you replaced the SCSI terminator or
SCSI cable and the problem persists, the fault is with the server’s
hardware or software. To isolate the cause of the failure, refer to the
server’s service documentation.

v If the error does not occur, connect one tape drive at a time back to the bus
defective.
Note: Ensure that the SCSI terminator is always on the last tape drive on the
SCSI bus.
4. Determine if the problem is with only one tape drive or with two or more tape
drives.
v If the problem is with only one tape drive, run the SCSI wrap test on that tape
– If the test runs successfully, replace the SCSI terminator first, then the
SCSI cable to that tape drive and interposer (if installed).
v If the problem is with two or more tape drives, locate the first tape drive that
has the error and replace the SCSI cable that connects the tape drive and
the interposer (if installed).
Fixing an Intermittent Error with a Single Drive on a SCSI Bus
1. Replace the SCSI terminator on the tape drive.
2. Run the operation that caused the error. If the problem persists, the problem
may be with the cable.
3. Isolate which cable is causing the problem by replacing one cable at a time and
running the operation that caused the error after each replacement. If the
problem persists after all cables have been replaced, the problem may be with
the Ultrium 2 Tape Drive.
on page 83). If the problem persists, the problem is with your server. Consult
your server’s documentation.
Fixing an Intermittent Error with Multiples Drives on a SCSI Bus
Refer to the server’s error logs to determine which tape drive is the source of the
problem:
v If only one tape drive is reporting a SCSI failure, replace that tape drive (see
v If multiple tape drives are reporting SCSI failures, the problem may be with the
terminator or the SCSI cables:
– Replace the terminator and run the operation that caused the error. If the
problem persists, the problem may be with the cables.
– Isolate which cable is causing the problem by replacing one cable at a time
and run the operation that caused the error after each replacement.

Fixing Fibre Channel Errors
If you are connected to a Fibre Channel Storage Area Network (SAN) by using a
SAN Data Gateway, use the IBM Storage Area Network Gateway Module Setup,
Operator, and Service Guide to determine whether the problem is occurring
between the drive and the SAN Data Gateway. If you are using a SCSI drive and
Starting Problem Determination

Resolving Media-Related Problems
To resolve problems that are related to media, the Ultrium 2 Tape Drive’s firmware
includes:
v Test Cartridge & Media diagnostic that verifies whether a suspect cartridge and
its magnetic tape are acceptable for use.
v Statistical Analysis and Reporting System (SARS) to assist in isolating failures
between media and hardware. To determine the cause of failure, SARS uses the
cartridge performance history that is saved in the cartridge memory (CM) and the
drive performance history that is kept in the drive’s flash erasable programmable
read-only memory (EPROM). Any failures that SARS detects are reported as
Attention: If you insert the IBM LTO Ultrium Data Cartridge into another
manufacturer’s tape drive, the SARS data in the cartridge memory may become
lost or invalid.
If you encounter a media-related problem, use the following procedure:
Attention: When you run the Test Cartridge & Media diagnostic, data on the
suspect tape is overwritten. Use only a scratch data cartridge to run the test.
1. If possible, run the tape cartridge in a different tape drive. If the operation in the
other tape drive fails and 6 or 7 displays, replace the media. If the operation
succeeds, run the Test Cartridge & Media diagnostic (see Function Code E in
