GETTING STARTED
This Chapter…
pcovers what you need (and what you need to
know) to install the ADIC Virtual Library
System. Read this section before you begin
installation.

2Getting Started
Introduction
ADIC has designed the Virtual Library System (VLS) for
high-capacity, near and off-line storage applications, such as
backup, hierarchical storage management (HSM) and
video/design/data file libraries. For the most part,
installation is simply a matter of checking all necessary
SCSI connections, installing the software (backup or
otherwise) and applying power. The defaults set at the
factory should be sufficient for most applications.
Requirements
8.0in.
20.3cm
17.4in
44.2cm
20.0 in.
50.8 cm
Figure 1: VLS Dimensions
pSpace requirements: the VLS footprint is 17.4" x 20.0" x
8.0". You must allow adequate clearance to the rear (2
inches or more) and bottom (do not place on carpeting)
to allow air flow. Also allow enough room at the front to
open the door (which is 8" high and hinged at the
bottom).

Getting Started 3
pWe assume that you are familiar with your computer
system. The VLS must be incorporated into the host
computer system. The backup software, SCSI adapter (if
required) and any additional, or different, SCSI interface
cable (s) must be purchased separately.
pMode of operation: You must know whether the VLS
will be operating in sequential- or random-access mode.
This will be determined by the backup software you use.
pNecessary tools: No special tools are required to install
the VLS. If you are installing a host adapter (SCSI
controller) card at this time, refer to the installation
manual for your host adapter.
Unpacking and Inspecting
CAUTION
If the operating environment differs from the storage
environment by 15ºC (30ºF) or more, let the unit
acclimate to the surrounding environment for at least
12 hours.
Unpack all items from the carton. Save the packing materials
in case you need to move or ship the system in the future.

Equipment Description
The VLS Unit
The ADIC VLS is a fully automated, high performance, high
capacity, mass storage system designed with a removable
data cartridge magazine. The door can be locked to
deactivate the unit's keypad and to assure only authorized
removal of the magazine and media. In addition, to protect
the unit, data and media, the VLS will not operate unless the
door is closed.
Drives
The ADIC VLS can be equipped with any of the drives
listed in the following table:
íAll drives are available
configured for operation
with a single-ended or
differential SCSI bus.

Magazine
íADIC strongly
recommends that you
use ADIC approved DLT
media only.
The magazine for the VLS holds seven DLT cartridges. It
includes a clear dust cover to protect the cartridges and for
ease of storage. Figure 3 shows a DLT cartridge and a filled
magazine with the cover in place.

Figure 4: DLT Data Cartridge
The write-protect switch is used to prevent recording over
existing data. To prevent recording or deleting, place the
write-protect switch to the open position. The drive senses
the position of the switch and will not allow writing in this

Getting Started 7
position. When installing cartridges in the library, place the
switch in the closed position (unless you do not wish to
record on a specific cartridge).
If the switch is moved all the way to the left, the cartridge is
write-protected and the drive cannot write to, or erase data
from, the cartridge. The small orange rectangle will be
visible whenever the cartridge is write-protected.
Additionally, an arrow (beneath the orange rectangle and
above the two lines on the switch), lets you know that data
cannot be written to the cartridge. If the switch is moved all
the way to the right, the cartridge is write-enabled and the
drive can write data to, or erase data from, the cartridge. The
orange rectangle will not be visible whenever the cartridge is
write-enabled. On the right side of the write-protect switch
an arrow over one line indicates that if you slide the switch
to the right, data can be written to the cartridge.
Note
•Store data cartridges in a dry, cool environment.
•Never reset or power down your computer or
VLS DLT while a function is in process or a
tape is moving. In addition to getting tape with
missing or corrupted data, you may also get tape
run-on within the drive (a condition that can
produce internal contamination requiring factory
cleaning).
•If a power outage occurs during a back-up
sequence, restart your backup from the
beginning.

8Getting Started
Cleaning Tape
íIf the cleaning cycle is
noticeably shorter and
the Use Cleaning TapeUse Cleaning Tape
LED remains illuminated
after a cleaning
attempt, the cleaning
tape has exhausted all
of its cleaning cycles.
Replace it with the same
type and repeat the
cleaning.
The tape heads should be cleaned when the Use Cleaning
Tape LED on the drive front panel is illuminated. A
cleaning tape is shipped with your ADIC VLS-DLT. Discard
it when there are no cleaning cycles remaining, and replace
it with the same or equivalent type cleaning tape.
Figure 5:. DLT Cleaning Tape
Cleaning the head should always be performed as the first
step if the Use Cleaning Tape LED is illuminated on the
drive front panel.
System Software
A variety of backup and data storage software is available
for use with the VLS. Please check with ADIC sales or
Customer Assistance if you have a question on the
compatibility of a particular software package.
