Speed matching
To improve system performance, the 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 six speeds when it reads
or writes the Ultrium 3 or Ultrium 4 cartridge format. Native data rates are as
follows:
v Ultrium 4 (read/write): 30, 48, 66, 84, 103, or 120 MB per second (MBps)
v Ultrium 3 (read/write): 30, 40, 50, 60, 70, or 80 MBps
2 LTO Ultrium 4 Half High Tape Drive
a80hh024
2
3
(LDI or ADI) selectable through feature
switch 5
v Ultrium 2 (read only): 15, 19, 22, 26, or 30 MBps
If the net (compressed) data rate of the server is between two of the active data
rates, the drive calculates the appropriate data rate at which to operate. 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.
Channel calibration
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 transfer function of the recording
channel, the media, and the characteristics of the drive head.
Encryption
The Ultrium 4 Half High Tape Drive supports host Application Managed
Encryption (AME), using T10 encryption methods. Data encryption is supported
with LTO Ultrium 4 Data Cartridges only.
The encryption enabled drive contains the necessary hardware and firmware to
encrypt and decrypt host tape application data. Encryption policy and encryption
keys are provided by the host application, and no encryption setup is required (or
available) for this drive. A drive digital certificate is installed at manufacturing
time. Each drive receives a unique serial number and certificate. The T10
application might validate each drive instance by checking the digital certificate of
the drive.
SAS interface
®
Application-managed encryption is supported on Windows Server 2003, Linux
and Solaris. Encryption requires the latest device drivers that are available for the
tape drive. To download the latest device drivers, complete the following steps.
Note: Changes are made periodically to the IBM website. The actual procedure
might vary slightly from what is described in this document.
1. Go to http://www-947.ibm.com/support/entry/portal/.
2. In the Search within all of support & downloads text field at the bottom of
the screen, type tape files and press Enter.
3. In the list of search results, click the link Tape Files (index) - Software for tape
drives and libraries.
A drive with a SAS (Serial Attached SCSI) interface can be linked directly to
controllers. SAS provides better performance than 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 3.0 Gbps. In addition, SAS drives can be hot-plugged.
SAS drives auto-negotiate speed. There are no configurable topologies; therefore,
feature switches are associated with SAS.
The drive contains a dual-port, SFF-8482 SAS connector. The SAS connector
conforms to the Device Free (Plug) Connector form of the SFF-8482 standard
“Unshielded Dual Port Serial Attachment Connector” as defined by the SFF
,

Chapter 2. Installing the drive
Depending on the type of enclosure, installation procedures might vary. Refer to
the enclosure documentation for drive installation. The following generic
procedure can be used if the enclosure documentation is not available.
Avoiding drive damage
To avoid static electricity damage when handling the drive, use the following
precautions:
v Limit your movement. Movement can cause static electricity to build around
you.
v Always handle the drive carefully. Never touch exposed circuitry.
v Prevent others from touching the drive.
v Before unpacking and installing the drive into an enclosure, 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.
v When possible, remove the drive from its static-protective packaging and install
it directly in 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.
v Do not place the drive on the cover of the enclosure or on any other metal
surface.

Unpack the drive
About this task
Unpack the drive and store the packaging for future moves or shipping.
© Copyright IBM Corp. 2011 5
Acclimate the drive and media
About this task
Acclimation time is required if the temperature of the drive and media when
unpacked is different than the temperature of its operating environment (measured
at the front of the bezel near the air intake area as shown in Figure 4). The
recommended acclimation time is four hours after the drive has been unpacked or
one hour after any condensation that you can see has evaporated, whichever is
greater. When acclimating the drive, apply the following measures:
v If the drive is colder than its operating environment and the air contains
sufficient humidity, condensation might 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 four hours.

Power off the enclosure
Procedure
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.
Set the feature switches
The Ultrium 4 Tape Drive has eight factory-set feature switches by which the drive
is configured for various functions. The feature switches are preset to the Off
position at the factory but are described here in case you must change the
feature-switch settings for your application.
6 LTO Ultrium 4 Half High Tape Drive
a80hh010
The feature switches are on the rear panel of the tape drive. See 1 in the Figure 3
on page 2 for the location of the switches. The switches are labeled 1 through 8
and the On and Off positions are marked. The feature switches are defined in the
following table.
Table 2. Feature switch definitions

6 Reserved Reserved
7 Disable head brush ERP* Enable head brush ERP*
8 Reserved Reserved
Note: The default settings for the feature switches are all switches placed in the Off
position.
*The head brush error recovery procedure (ERP) is intended to prevent a permanent read
or write error by removing debris that might have accumulated on the read or write head.
In order to brush the head, the tape must be unthreaded to expose the head. This forces
the loader to be cycled to enable re-thread. During the loader cycling, the back of the
cartridge will temporarily extend beyond the front of the bezel. Extension of the cartridge
is problematic in some automation environments, so you have the ability to disable this
function. If the head brush ERP is disabled, the drive will immediately report the
permanent error instead of activating the head brush ERP.

Mount the drive in an enclosure or server
About this task
When you mount the drive in an enclosure, observe the following guidelines:
v Use the installation instructions for your enclosure if possible.
v Use the drive rails that come with your enclosure or server, unless you have
x3400 or x3500 System x servers. Mount the drive into x3400 or x3500 System x
servers using the metal rails included with your tape drive.
v Do not obstruct the ventilation slots at the rear of the drive.

Chapter 3. Operating the drive
Operating the drive involves using the following front panel items:
v Single-character display (SCD)
v SCD dot
v Status LED
v Unload button
Single-character display (SCD)
The SCD (2 in Figure 2 on page 2) presents a single-character code for:
v Error conditions and informational messages
v Diagnostic or maintenance functions (while in Maintenance Mode only)
“Error codes and messages” on page 46 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.
“Diagnostic and maintenance functions” on page 16 lists the single-character codes
that represent diagnostic or maintenance functions. To initiate a function, the unit
must be in Maintenance Mode.
SCD dot
Status LED
The SCD is blank during normal operation.
If a drive dump is present while the drive is in Maintenance Mode, a single red
8
dot illuminates in the lower right corner of the SCD (
“Function Code 5: Copy drive dump” on page 24.
The SCD Dot is on solid if the dump is in ROM memory. The SCD Dot flashes if
the dump is in FLASH memory.
The SCD Dot turns off when you obtain a dump (by using ITDT, a library
command, a SCSI command, or "Function Code 5: Copy Drive Dump) or update
the drive firmware.
Note: If the drive dump is stored in ROM memory (SCD Dot on solid), the dump
will be lost when you turn OFF the power or reset the drive.
The status light-emitting diode (LED) (4 in Figure 2 on page 2) that provides
information about the state of the drive. The LED can be green or amber, and
(when lit) solid or flashing. Table 3 on page 12 lists the conditions of the status
light and single-character display (SCD) and provides an explanation of what each
condition means. The SCD dot – a small LED dot near the lower right corner of
the single-character display – serves as a dump indicator. When this dot is lit, a
dump file is stored in the drive and can be retrieved.
