Introduction
This chapter descri bes the features of t he expansion and base modules of the
MiniLibrary System, including Storage Archite cture, SCSI Interface, Bus
Performance, and Physical Configuration/Expansion Options.
The MiniLibrary System is an expandable, modular tape library system
combining DLT te chnology drive with advanc ed robotics. The MiniLibrary
System is designed for high duty-cycle on-li ne and near-on-line appl ications,
such as hierarchic a l st ora ge mana ge men t (HSM). It is a super ior per forme r in
high-volume backup and archival service as well.
Modules
Two types of modules comprise the MiniLi brary System:
■
Expansion Unit (Master)
■
MiniLibrary (Base Module)
The MiniLibrary System consists of one Expansion Unit and up to five
MiniLibrary base modules stacked in a rack. The Expans ion Unit can move
media freely between itself and Base Modules via the system’s roboticallycontrolled pass-through mechanism.
In a MiniLibrary System, you can combine modules to provide the ri ght
combination of c apacity and performance t o meet your present storage
requirements. Compaq’s MiniLibrary storage architecture lets you add
modules to optimize throughput and capacity as your ne eds chan ge .

MiniLibrary Storage Architecture
When connected as a system, the robotics in the MiniLibrary Expansion Unit
act as commanded by the host computer(s). The host(s) need no knowledge of
the internal geometry of the system, or of the actions or capabilities of the
Base Modules.
The Expansion Unit presents to the host(s) a single SCSI medium changer
device with a single SCSI Medium Transport element, a number of SCSI
Storage elements equal to the total number of cartridge magazine slots, a
number of SCSI Import/Export elements as specified by the user during
configuration of the Expansion Unit, and a number of SCSI Data Tra nsfer
elements equal to the total number of drives in the system.
Flexibility
Compaq’s MiniLibrary storage architecture is uniquely suited to growing
storage needs. Its flexible library robotics system enables you to start with a
system configured to your present requirements, confident that as your storage
needs evolve, you can easily modify the MiniLibrary by adding modules and
extending the pa ss-through mechanism. Add dri ves for faster performance or
magazine space for greater capacity, as needed. Then just turn on the power,
and immediately the system updates the system map so the host i s informed of
the expanded capability.
Multi-Server Data Sharing
A host computer with a SCSI controller connected to a bus is a SCSI Initiator.
The Expansion Unit is a SCSI Target. SCSI rules permit multiple Initiators on
a single bus. T herefore, with the prope r host software, it is possible to connect
multiple hosts to a single Expansion Unit over a single SCSI bus. This allows
multiple hosts to operate the library robotics, loading and unloading cartridges
as each host requires.
In a system with many drives, it is desirable to use multiple SCSI buses for the
drives, so the data transfer rate of the drives is not limited by bus bandwidth.
In a large, high-performance system, drives ma y be connected to separate
hosts. Using special software, one of the hosts can act as a master server,
processing all robotic s commands. In this way several hosts may share a
common data ba se.

The Expansion Unit
Description
The Expansion Uni t integrates the robotics in the individual modules into a
single coordinated library robotics system. The Expansion Unit performs and
maintains an inventory of all media present in the system, including bar code
data. All necessa ry system control operations may be performed from the
control panel of the Expansion Unit, as well as from the host via software. The
SCSI interface for the library robotics is designed for high-speed
communication with the host, and Fast/Wide SCSI configurations.
In addition to it s system control functi ons, the Expansion Unit has a 16cartridge magazine with a rugged random a ccess robotic mechanism. T he
module robotics move s cartridges between the pass-through mechanism and
any of the 16 cartridge storage locations.
The user may designate a magazine in one of the base modules as a mail slot
for inserting or removing one or more single cartridges, which imple ments the
SCSI Import/Export c ommands.
NOTE:
A magazine that has been reserved for Import/Export service may not be used for
data storage.
Introduction 1-3
The Base Module
Description
The Base Module has one or two TZ 89 tape drives and a 10-cartridge
magazine with a rugged random access robot ic mechanism.
Models
The TL891 using one or two TZ89 seri es drives, also use the DLTtape IV
cartridges, which provide a native capacity of 35 GB per cartridge. All models
can also read and write DLTTape III and DLTtape IIIxt cartridges. Both read
and write densitie s are selectable from the front panel, and under SCSI control
from the host.

SCSI Interface Configurations
Systems are equipped with TZ89 drives use a Fast/Wide SCSI interface using
high-density 68-pin D-series connectors. The section on SCSI Interfaces in
Chapter 3, Inst allation, describes the available interface options.
SCSI Bus Performance Considerations
Data Transfer Rate
The data transfer rate of the MiniLibrary is dependent on the type and number
of drives and on the SCSI bus configurat ion. The bandwidth of the SCSI bus is
limited. As a result, the transfer rate of exceptionally fast drives such as the
TZ89 can be li mited by sharing a SCSI bus with another disc drive on tape.
Drives
With a standard SCSI interface, modules e quipped with TZ89 drives have a
native data transfer rate of 5.0 MB/second, 10 MB/sec for two drives. The
rates for compresse d data are dependent on compression ratio, record size,
data type, and other system parameters, but averages approximately 1:7.
Internal Cabling Configuration
The MiniLibrary System is wired in an i ndependent-bus SCSI configurati on.
That is, the robotic s and each of the drives has its own SCSI bus. SCSI
jumpers are available for those applications requiring that some combination
of drives and robotics be daisy-chained to a single SCSI bus. These
configurations are de scribed in more detail i n the section on SCSI Interfaces in
Chapter 3, Inst allation.

Part Number: ER-TL891-UA.A01 File Name: b-ch1 Introduction Last Saved On: 3/1/99 4:07 PM
Physical Configuration
The Expansion Uni t must be mounted at the top of the stack, which places its
control panel at a convenient height. The control panels of the Ba se Modules
are of secondary importance, as they serve main ly to help localiz e sys tem
failures. When installed, the motor drive assembly of th e p as s - th rough
mechanism is directly behind the Expansion Unit.
Base modules may be installed anywhere below the Expansion Unit, in any
order. There may be a slight performance advantage in making the Base
Modules contiguous, but gaps are permitted. The size of a gap is limited by the
fact that each ga p must be bridged by some number of 7” pa ss-through
mechanism track sections. For safety, available cover plates should be
installed on all pass-through mechanism sections that are not connected t o
MiniLibrary module s.
The Expansion Unit senses the position of each module during initialization at
power-up. Even i f there are gaps betwee n modules, the system will operate
correctly. If you plan to leave gaps betwee n modules, be sure t o order
additional p ass - through mechanism track segments and cover plates equa l to
the length of the gap.
Introduction 1-5
System Expansion
A MiniLibrary System may be expanded in capac ity and perfo rm anc e by
adding or removi n g TL891 modul e s. Asso ci ated with the Expansion Unit and
each of the Base Module(s) is a section of the pass-through mechanism.
System firmware inte grates all of the robotics of these system m odules with
that of the pass-through mechanism into a single high-performance libra ry
robotics system.

Magazine Security Lock
The Magazine Sec urity Lock is a key-operated switch on the front panel of
each module. It can be used to prevent inadvertent removal of the cartridge
magazine.
Power Supply
The AC Power switch is located on the front panel of the module. The
autoranging power supply will adjust automatically to either of two operating
voltage ranges. The ranges are 100-120 VAC and 200-240 VAC. The power
supply is capabl e of operating at 50 or 60 Hz without any adjustment or
modification. AC power is supplied to the power supply by a single IECcompatible socket t hat can be connected to any properly grounded outlet.
Tape Cartridge Magazines
The 10-cartridge and 16-cartridge magazines are removable from the front
panel, but may be protected from tampering by any of three means: 1) a keyoperated Magazine Security Lock which must be unlocked before the
magazine can be removed, 2) an electronic combination lock operated by
using buttons on the Expansion Unit control panel, and 3) issuance by the host
of a SCSI ‘Prevent Medium Removal’ comma nd. The rugged carbon-fibe rreinforced polymer mag azine fits into an extruded track , which assures precise
positioning with respect to the library robot ics. A 10-cartridge tape ma gazine
is shown in Figure 1-3. Insertion and re moval of the magazine is described in
Chapter 2, Ope ration.

Advanced Design Features
The MiniLibrary System incorporates many signi ficant improvements in ta pe
drive and library design. One of the m ost important is the use of highly
reliable DLT tec hnology, with media rated by the media manufacturer at better
than 1,000,000 hea d passes.
Embedded Diagnostics
The MiniLibrary System and each of its modules provide three levels of
embedded diagnostics. The Power-On Sel f Test (POST) performs various
verification tests on the system’s configuration and host interface and de vice
control functions, a s well as memory tests, at power-up. The second level of
diagnostics is the User Diagnostics, which provide for displaying and
changing configuration options . The third lev el, Custo mer Engin eer (CE)
Diagnostics, include advanced diagnostics to be used by Customer Engineers
for servicing the MiniLibrary System. Both the User Diagnostics and the CE
Diagnostics may be selected from the front panel.
User Diagnostics are described in greater detail in Chapter 3, Installation.
Error Checking
Drives used in the MiniLibrary System apply a 16-bit parity check to each
record, a 64-bit CRC to each 4 kb of data, and Reed-Solomon error correction
code overall. In addition, there is an inte rnal parity check on the data buffer.
Compression
MiniLibrary System drives use the standard Digital Lempel-Ziv (DLZ) data
compression algorithm.
Capacity
A Base Module with its 10-cartridge magazine and a single Expansion unit
with its 16-cartridge magazine offers the formatted capacities shown in Table
1-1.

Tape Requirements
The MiniLibrary System use s ECMA-approved and ANSI proposed-standards
DLTtape cartridges. The DLTtape cartridge is a four-inch square plastic
cartridge. According to the media manufacturer, the cartridge and the medium
are designed to withstand 1,000,000 passes, a nd to have a shelf life of 30 years
when properly stored.

Cartridge Handling and Storage
A DLTtape cartri dge should be stored vert ically until you select it for use. Do
not expose a c artridge to moisture or di rect sunlight. Maintain a clean, dustfree working and storage environment.
If a DLTtape ca rtridge is dropped:
■
Inspect the cartridge carefully before you inser t it into a MiniL ibrary
magazine or any drive.
■
Shake the cartri dge while listening for the sound of a broken part . Any
rattling sound make s a cartridge unfit for use.
■
Inspect the case for distortion or cracks.
■
Inspect the leader by opening the cartridge door as shown in Fi gure 2-
43. The leader should be positioned as shown in view (1), and should
protrude at about a five-degree angle from the case. If the leader is out
of position, do not use the cartridge; dam age to the drive could result.
Under certain conditions, DLT Tape may stic k to the drive read/wri te head
during operation. Damage to media, failure of commands or batch jobs to
execute, with resulting errors or hangs; failur e to unload; apparent need to
swap out the drive.
When tapes are stored in an environment different from that of the drive,
ensure that they are acclimatized, by moving them to a location in close
proximity to the drive before attempting t o use them. Ideally, t apes should be
allowed to acclim ate for a time equal to the duration of their storage away
from the drive, or 24 hours, whichever i s less.
Reports have verified that sticking will occur almost immediately with older,
used tapes which have been stored at 20°C and 75% humidit y, when those
tapes are used in a TZ87 drive kept at a higher temperature and lower
humidity. Hig h tape humidity ca uses sticking from HYDROLYSIS, a
degradation of the tape which can be re versed by storing the ta pe for a while in
a dry environment Test conditions (cool, damp tapes and warm, dry drives)
have produced “stiction” at will, but other conditions may also cause it.
Remember to accl imatize tapes before use. Long-term storage specificat i ons
are more stringent than those for shorter periods. Cartridges intended for longterm archiving shall be stored in room conditions of 23°C +/-5 (73°F +/-9 at
50% +/-10% relative humidity.

Planning Your Installation
The MiniLibrary System is intended to be mount ed in a Compaq Cabi ne t,
StorageWorks SW500, SW600, SW800 or a standard 19-inch EIA/RETMA
equipment rack with a depth of 24 to 30 inches. Each module is shipped with
EIA/RETMA slides installed. Addi tion al hardware for mounting in Compaq
and SW500, SW600, and SW800 cabinets is included
Every Compaq MiniLibrary System includes:
■
One Expan s io n Unit
■
One Expandable Pass-Through Mechanism
■
One to five Base Modules, each with one or two TZ89 drives
The Expansion Uni t has 16 slots and no drives, and serves as controller of the
MiniLibrary System. The base modules each have 10 slots plus one or two
drives. The Expansion Unit and the Base Module(s) each oc cu py 7 inches of
rack space height.
The Pass-Through mechanism is composed of a motor drive assembly plus
sections of track whose combined length is equal to the combined heights of
the Expansion Uni t plus the Base Modules. One extension section of track is
needed for the installation of each additional MiniLibrary module.
Installation 3-3
Positioning the Modules
The Expansion Uni t must be mounted at the top of the stack, which places its
control panel at a convenient height. The control panels of the Ba se Modules
are of secondary importance, as they serve main ly to help localiz e sys tem
failures. When installed, the motor drive ass embly of the Pass-Through
mechanism is directly behind the Expansion Unit.
Base modules may be installed anywhere below the Expansion Unit, in any
order. There may be a slight performance advantage in making the Base
Modules contiguous, but gaps are permitted. The size of a gap is limited by the
fact that each ga p must be bridged by some number of 7” Pass-Through
mechanism track sections. For safety, available cover plates should be
installed on all Pass-Through mechanism sections which are not connec ted to
MiniLibrary Syst em mo dules.
The Expansion Unit senses the position of each module during initialization at
power-up. Even i f there are gaps betwee n modules, the system will operate
correctly. If you plan to leave gaps betwee n modules, be sure t o order
additional Pass-Through mechanism track segments and cover plates equal to
the length of the gap.

Orientation of Parts During Assembly
To determine the orientation of an extension section, examine the flanges on
the edges o f the sect io n, and note that th ey are diss imilar. Position the sec tion
so that its orientation matches that of the elevator base.
Figure 3-4 shows a typical pass-through m echanism assembly. The mot or
drive section always goes on top, and the base section with the idler pulley
always goes on the bottom. Extension sec t ions are mounted between the motor
drive section and the base section. All sections are joined together with tie
bars. For system s up to four modules, two support braces are nee ded, one
attached to the motor drive and one to the base section. For larger systems, a
third support brac e should be mounted near the center of the pass-t hrough
mechanism.
Preparing to Assemble the Pass-Through
Mechanism
You will need a clean, flat work area such as a table or work bench. The
surface should be long enough to support the full height of the pass-through
mechanism. The height is equal to the height of the stack of modules in your
system plus any gaps you intend to include in the stack. Use the following
procedure to asse mble your pass-through mec hanism.
Assembling the Pass-Through Mechanism
In most cases, you have received a pre-a ssembled pass-through mecha nism. If
its length is correct for your system, turn to the section entitled Mechanical
Installation of the Expansion and Base Modules and continue on to the end of
the chapt er. If yo u n eed to add sections , please take a few minut es to read this
section and the section entitled Installing the Belt, before procee ding to Adding
to an Existing Pass-Through Mechanism .
NOTE:
References to left and right refer to the position of the part when the pass-through
mechanism is assembled and mounted in the rack, as viewed from the front of the rack.
Refer to Figures 3-1 and 3-4.
1. Place the base se ction, with the inside facing down, overhanging the
right end of the work area, with the bottom plate of the section toward
the right.
2. Place each of the extension sections, with the inside facing down, in a
row aligned edge-to-edge beginning with the base section. The bottoms
of the sections should be toward the right. Omit the motor drive at this
time.

Mechanical Installation of the Expansion and
Base Modules
The Expansion Unit and Base Mod u le ( s ) may be rackmounted in either a
Compaq rack, a standard 19” EIA/RETMA rack (with a depth of 24-30”) or a
StorageWorks (SW500, SW600, or SW800) met ric rack using metric
conversion brackets. Both rack types require two initial steps:
1. Separati n g the rack-slides .
2. Attaching the mounting-brackets.
This section describes these common rackmount instructions, followed by
rack-specific rackmount instructions. The cabling and configu ra tion
procedures for al l rackmounted MiniLibraries are described in the se ction
entitled Interfaces and Cabling.
Follow the directions in the shipping container to unpack the module(s). Save
the packing materi als for re-use in case you need to return t he module(s) for
repairs.
The Expansion Unit and the MiniLibrary Base Module comes with a slide rack
set installed on either side. The slide is attached to the Base Module enclosure
by means of three screws through the i nner slide. Remove the pac king tape
from the slides, and separate each set of slides as follows:

Installing the Pass-Through Mechanism in the
Rack
1. If you have not previously done so, insta ll the angle brackets on the rack
slide extensions of the top and bottom module s, using one 10-32 screw
and an L-shaped nut plate for each angle bracket. The L-shaped nut
plates should ha ng from the top of the slide extensions on the outside.
Place the angle brackets so the front edge of the vertical part is 15/16”
behind the rear edge of the slide body, as shown in the inset in Figure 3-
14.
2. Referring to Figure 3-14, position the pass-through mechanism against
the back of the installed modules so tha t the support braces rest on the
previously installed angle brackets. Install an M4 x 20 mm screw and
washer through the rear hole in each angle bracket into the support
braces. Do not tighten.
3. Look closely at the right flange of the pa ss-through mechanism (le ft side
as viewed from the rear of the rack) as shown in the inset in Figure 3-14.
At the top m odule, position the pass-through mechanism horizontally so
that the edge of the flange fits exactly into the slot on the rear of the
chassis of the top and bottom modules.

4. Ensure that the bottom edge of the pass-through mechanism motor drive
section is flush with the bottom surface of the module chassis. If
necessary, adjust the vertical position of the angle brackets.
5. Repeat steps 3 and 4 at the bottom module. Tighten all of the scre ws that
hold the pass-through mechanism to the angle brackets while ensuring
that:
6. The pass-through m echanism is centered horiz ontally, as indicated by
the flange enga ging the slot on the top and bottom modules, and
7. It is centered vertically, as indicated by the bottom of the bottom of the
pass-through mecha nism being flush with the bottom of the lowest
module , an d
8. The pass-through m echanism is pressed firmly against the backs of the
top and bo ttom modules.
9. One by one, push the remaining modules into place and tighten the
captive screws. In each case, ensure that the module does not bind
against an adjacent module, that clearance between modules is evenly
divided between t op and bottom, and tha t the flange on the pa ss-through
mechanism engages the slot on the back of the module.
10. If binding occurs, or if the module is not centered on the pass-through
mechanism, loosen the four screws that secure the slides of the bindi ng
module to the front rails and the four screws that secure the slides to the
rear rails, reposition the slides, then retighten the screws.

Refer to Figure 3-15. The connections requi red depend on the type of module.
The Expansion Unit always has the SCSI connection to the host for the library
robotics. Base modules have a separate SCSI connection to the host for each
drive*, but the SCSI connectors for the robotics should not be used. The
portion of the library robotics that is loc ated in the Base Modules is controlled
by the Expansion Unit through a cable connected to the Expansion Interface
connector on each module. Each module has a separate AC power connection.

drives, to save SCSI controllers. Compaq strongly recommends against this practice
because it may severely limit the data throughput performance and reliability of the
library.
In principle it is possible to daisy-chain the SCSI connections for multiple

Power Cord
The detachable AC power cord is a sta ndard grounding AC cord which
attaches to an IEC-compatible connector on the rear panel. Connect a cord to
the connector on each module, and connect the other end to a reliably
grounded AC out let or rack power out let.
To maintain safety compliance, use a power cord with a suitable ra ting that is
approved for the c ountry in which the product is used. In the USA, cords must
be UL listed, in Canada, CSA certified, and in Europe use a Harmoni zed cord
marked <HAR> or a nationally certified cord. Compaq specified power cords
are available as part of the associated TL891 Country Kits (Ordered
separately.)
SCSI Interfaces
MiniLibrary Modules come with a differential Fast/Wide SCSI and one or two
TZ89 drive(s). Fast/Wide SCSI is available as differential, and uses two
parallel female high-density 68-pin D-Series connectors per bus. Fast/Wide
SCSI cables and terminato r s ar e secured to the connec tor s b y jackscrews.
NOTE:
Compaq strongly recommends that you use differential controllers and highquality SCSI cables to ensure the highest performance of your MiniLibrary. Bus errors
caused by excessive length or poor quality cables can significantly degrade performance
and reliability.
In the Base Module, each drive is wired to an independent bus with a pair of
SCSI connectors. Because it can be used in free-standing applications, the
Base Module has a pair of SCSI conne c tors for that module’s library robotics.
The library robotics SCSI interface should not be c onnected when installed in
a system with an Expansion Unit. The Expansion Unit controls the library
robotics for all of the modules in the system. It has a single SCSI bus, with a
pair of SCSI connectors, to enable a host to control the library robot ics .
Each of the drives in the system and the library robotics is a separate SCSI
device and is wired to a separate SCSI bus. Any of the separate buses may be
combined using a SCSI jumper cable, available from Compaq. If any two or
more devices are connected to the same SCSI bus, each must be assigned a
unique SCSI addre ss. Fo r in for mati o n on assi g nin g SCSI add resses, see the
section entitled Confi guration.

Installation 3-31
NOTE: For best performance, no more than two TZ89 drives should be connected to a
single SCSI bus, because of the bandwidth limitations of the SCSI bus.
A terminator of the proper type (68-pin differential) must be installed on each
unused connector at the end of each bus, a s explained below in the section
entitled Interface Cable and Terminator Installation. Figure 3-15 shows the
SCSI cable, connectors and bus terminator us ed on the module.
In order to connect a module to a host computer system, the host system must
have at least one SCSI controller and the appropriate driver software. As noted
earlier, higher-speed drives may require the use of separate SCSI controllers
for each drive or each pair of drives. No more than two TZ89 drives should be
connected to a si ngle SCSI bus. Your Technical Support representati ve is
available to answer your q u es tions about installation procedures for specific
host systems. Before cabling the system, see the recommended SCSI ca ble
specifications in the following section. Also, see the section entitled I nterface
Cable and Termi nator Installation.
Interface Cable Specifications
The MiniLibrary is a high-performanc e syste m. To avoid degr ada tio n of
performance, use the highest-quality interface ca bles. The detailed
requirements for SCSI cables ar e set forth in ANSI X3.131-1994. All SCSI
cables used with the MiniLibrary Module meet at least the following
requirements:
■
Shielded or doubl e-shielded, as required to meet EMI specifications;
■
Impedance match with cable terminators of 132 ohms, ideally;
■
Charact er istic impedance betw een 90 and 132 ohms , r equired;
■
Each end of the twisted pair ground must be connected to chassis
ground;
■
The maximum cable length for a differential Fast SCSI bus is
82 ft. (25 m)
IMPORTANT: When calculating the overall length of the bus, be sure to include the
internal cabling of the module, which is as follows:
MiniLibrary Base Modul e:
Fast/Wide (TZ89 Drive)
DLT0 14 inches (36 cm)
DLT1 23 inches (57 cm)
Expansion Unit: 32 inches (81 cm )
■
Cables of different impedances should not be used together.

Additional specificat i ons to assure the hi ghest SCSI performance c an be found
in ANSI X3.131-1994 or late r.
NOTE: This equipment has been tested for electromagnetic emissions and immunity
using good quality shielded cables. The use of unshielded cables, poor quality cables or
other variances from good practice may result in non-compliance with national and
international rules.
Terminators
A terminator must be installed on the device if the device is to be used at either
end of a SCSI bus, such as the first or last device along a daisy-chain, or as a
single SCSI peripheral. The appropriate type a nd quantity of termina t or is
shipped with your module. They are packaged in the accessory bag that arrives
with the module.
NOTE: It is important to use only differential terminators on a differential SCSI bus.
Interface Cable and Terminator Installation
To properly cable a module:
1. Make sure that your host system has an a ppropriate SCSI interface card
for each SCSI bus and software drivers installed.
2. Inspect the terminator and make sure it is a differential type. SCSI
terminators should be clearly marked ‘single-ended’ or ‘differential’.
3. Determine whe the r the module is to be con ne cted in daisy-chain fashion
with other device s.
4. If not used in a daisy-chain, install the terminator in the second SCSI
connector.
5. If used in a daisy-chain, and the drive is the last device of the chain,
install the terminator in the second SCSI connector. Otherwise, do not
use the terminator. Connect the next cable in the chain to the second
SCSI connector.
6. Make sure that the cable you use meets the specifications listed earlier
in this chap ter.
7. Measure the cable length to connect the module to the computer syst em.
8. Be sure that the length of the entire bus falls below the maximum
permiss ib le length given in th e secti on en titled Interface Cable
Specifications.

Configuration
Individual MiniLibrary Base Modules in all newly assembled systems must be
configured as de scribed in the next section. In addition, the MiniLi brary
System is designed with several configuration options, each offering multi ple
settings to support a variety of applications and platforms. The setting of each
option is stored i n non-volatile memory in the module. For most applications,
you will not ne ed to change the factory default settings.
To change settings, you need to use the control panel on the Expansion Unit.
For an overview of how the control pane l works, and a descript ion of the
functions of the buttons, indicators and di splay, refer to sections e ntitled
Entering the Menu Mode, Exiting the Menu Mode, and Navigating Through
the Menu Structure in Chapter 2, Operation.
The settings can be changed using the procedure described in the se ction
entitled A Configuration Example - Setting the SCSI ID, covered later. Before
changing any configuration settings, consult your host system documentation
to determine which settings may need to be changed.

Setting up a Mail Slot
Some of the available host software enables the system administrator to limit
access to the library as a whole while permitting insertion into or removal
from the library of one or more tape ca rtridges when needed. Thi s feature is
commonly called a mail slot. It is impl emented using SCSI Import /Export
elements.
In the MiniLibrary system, you can designate the magazine of any Ba se
Module as the mail slot magazine. When you do so, the entire magazine is
withdrawn from the list of storage element s. You can designate any number of
mail slots from one slot up to the full size of the magazine. To configure a
mail slot, use the following procedure.
1. As shown in Fi gures 3-25 through 3-27 in the preceding procedure,
navigate from the Default Screen through the Main Menu to the

Descriptions of Configuration Options
Table 3-2 summari zes the configuration setti ngs for the MiniLibrary System.
The items available on the Configuration Menu are as follows:
Set Data Format: This setting enables you to 1) set the data format to Auto
Selection, THZ01, T HZ02, DLT2000, DLT2000XT, DLT4000; or DLT7000;
and 2) Auto Se lection, enable, disable data compression. Compression ca n not
be enabled when either THZ01 or THZ02 format is in use. This setting applies
to the next or currently loaded cartridge only. An unload command returns to
the default. This setting does not display the current format of the loaded tape.
Use the Show Status Menu for this purpose. The default for densi t y and
compression is Auto Selection.
Set SCSI: This setting enables you to 1) enable or disable the library robotics
SCSI bus parity checking, and 2) set the SCSI addresses of the drives and the
library robotics. T he defaults are: parity e nabled; Library Bus ID = 0. The
designators DLT 0 through DLTn refe r to the first through nth drives, counting
from top to bot tom. The actual designator used by the system depends on the
number of drives in the system and the placement of the module in the system.
Set Library Mode: This option enables you to set the library roboti cs
operating mode t o Random, Sequential DL T0, Sequential DLT1, or Sequential
Split. Random is the normal operating mode which affords complete host
control of the li brary robotics. The Sequential modes are locally cont rolled
modes. Sequential DLT0 begins with any cartridge loaded into DLT0. The
Base Module moni tors the status of DLT0, and when the cartridge is unloaded
by the host, it loads the next cartridge in magazine numerical order. This
operation continues to cycle until all of the cartridges have been loaded.
Sequential DLT1 is the same, except that the cartridges ar e lo aded into DLT1.
Sequential Split mode provides two simultaneous sequential modes. Cartridges
0 through 4 are loaded sequentially into DLT0; cartridges 5 through 9 are
loaded sequentially into DLT1.
Set Element Base: This setting allows you to set the base addresses of each of
the four SCSI elements of t he module. In order to i dentify sources and
destinations in commands to the robotics, the Library System is divided into
elements, each of which is assigned a separate designator or element address.
The Transport Element is the robotics mechanism itself; the Storage Elements
are the slots in the magazines; the Transfer Elements are the drives, and the
Import/Export Elemen t is the mail slot or sl ot s. The Module reports these
settings in response to the SCSI Mode Sense command , in the Element
Address Assignment Page. The defaults a re Transport element base = 0000,
Storage element base = 0001, Transfer element base = 00F0, and
Import/Export element base = 00E0.
