Q24/Q48 Tape Library Installation and Operations Manual
1 Product Overview and Features
This manual provides information about installing, operating, troubleshooting and servicing a Qualstar
Q24 or Q48 Tape Library. It is intended for system administrators and general users who need
physical and functional knowledge of the Q24 or Q48 Tape Library.
The two libraries are similar, physically and functionally. The primary difference is the height of the
Q48. The Q48 is twice the height of the Q24. The Q48’s added height increases the tape cartridge
capacity to 48 slots, and the number of tape drives to a maximum of four.
This document uses the reference Q24/Q48 to refer to either the Q24 or the Q48 Tape Library.
The Q24/Q48 Tape Library provides a compact, high capacity, low-cost solution for simple,
unattended data backup. It is compatible with most host operating systems and environments
provided the host is equipped with the appropriate interface card. However, the library requires either
direct support from the operating system or a compatible backup application to take full advantage of
its many features.
Major characteristics of the Q24/Q48 Library include:
• Platform – support for either one or two half-height LTO5 or LTO6 tape drives in a Q24 Tape
Library, and one to four in a Q48 Tape Library.
• Connectivity – Fibre Channel (FC) and/or Serial Attached SCSI (SAS) depending upon
installed tape drives
• Expandability – additional half-height tape drives may be field-installed in a library that has
unused drive slot locations.
• Technology upgrade – tape drive technologies can be upgraded in the field (i.e. LTO5 to LTO6)
• Service friendly design – easy access to magazines, tape drives, library controller and power
supply for field replacement
• Maximum up time – through advanced error handling and recovery capability
The Q24/48 Library includes the following features:
• USB interface to enable serviceability features (library and drive firmware upgrades) and/or
customized features (storage on demand) implementation
• The library can be operated via the front operator control panel (OCP), over the network or the
Internet via the integral remote management unit (RMU), or via the storage interface connection
from the host application
• Supports industry standard management protocols such as SNMP (SMI-S future development)
• The Q24 has one mail slot for import/export of cartridges during library operation while the Q48

2.2 Serial Attached SCSI (SAS) Requirements
Serial Attached SCSI (SAS) is a computer bus technology mainly used to transfer data to and from
storage devices, including disk drives and tape drives. SAS is designed to transfer data at up to
6 gigabits per second.
SAS uses serial connections, with a direct connection between the host server and each of the storage
devices. This eliminates the need to configure SCSI buses and assign SCSI IDs, as was required for
parallel SCSI devices.
Most SAS host bus adapters (HBA) ports have four SAS channels. A tape drive uses one channel, so
each HBA port can support up to four tape drives via a fan-out cable. You can use a cable with one
connector on each end, but only one channel will be used.
Q24/Q48 Tape Library Installation and Operations Manual
NOTE
The library has a mini-SAS connector on each SAS tape drive.
Mini-SAS connectors are keyed.
A SAS tape drive is identified by a unique identifier called a World Wide Name (WWN) or World Wide
Identifier (WWID). The library assigns the WWID to the drive bay. When a tape drive is replaced, the
WWID is re-assigned to the new tape drive.
The operating system tracks the WWID for the tape drive on each HBA channel. Each of the drive
connectors on the fan-out cable is associated with an HBA channel. Once a tape drive has been plugged
in, it should remain on the same channel to retain the association between the HBA channel and
WWID.
2.3 Fibre Channel Requirements
Fibre Channel (FC) allows an active intelligent interconnection scheme, called a Fabric , to connect
devices. Everything between the ports on FC is called the Fabric. The Fabric is most often a switch or
series of switches that takes the responsibility for routing.
The library allows the selection of the following Fibre Channel port behaviors:
• LN Port (default setting) – an automatic configuration that tries arbitrated loop first, then switched

NOTE
Use an appropriate HBA for your tape drive due to performance
library.
• L Port – arbitrated loop
Figure 9 Fibre Channel topology (L Port)
• N Port – point to point protocol in a switched Fabric topology
Figure 10 Fibre Channel topology (N Port)
The Fibre Channel tape drive can be connected directly to the server with a host bus adapter (HBA) or
through a storage area network (SAN).
In a SAN installation, all switches between the host and the
considerations. A lower throughput HBA might result in
performance degradation when backing up highly compressible
data to a higher throughput tape drive.
library must be of the appropriate type. A lower throughput
switch in the path may result in performance degradation.

To connect the FC cable to the tape drive:
1. Remove the FC port caps if necessary. Attach one end of the FC cable to [Port A] on the tape drive.
Figure 20 Connect the FC cable
2. Attach the other end of the FC cable to a switch or host bus adapter (HBA).
2.12.3 Connecting a SAS cable
Each SAS tape drive has a mini-SAS connector.
Mini-SAS connectors are keyed.
To connect the SAS cable to the tape drive:
1. Plug the HBA end of the SAS cable into the connector on the HBA.
• If you have a SAS fan-out cable, the end of the cable with only one connector, should be plugged
into the connector on the HBA.
Do not force a SAS cable’s mini-SAS connector into the tape
drive mini-SAS connector because it might be keyed differently.
SAS signal rates require clean connections and a minimum number
of connections between the HBA and the library.
Do not use adapters or converters between the HBA and the
library.
• If you are using a cable with a single connector on each end, plug the other end into the
connector on the tape drive.
• If you are using a SAS fan-out cable, plug one mini-SAS connector into the connector on each
tape drive. The unused ends of the SAS fan-out cable are single channel and not suitable for use
with disk arrays. Use the other ends to connect tape drives, or coil and secure them to the rack
to minimize stress on the connectors.
2.12.4 Connecting an Ethernet cable and a USB device
To connect the Ethernet cable to the library:
The connection to the Ethernet network is via an industry standard RJ45 copper interface on the rear
panel of the library. The Ethernet connection is used to access the library RMU over a network.
To connect the library to the Ethernet network, insert the Ethernet cable into the Ethernet port of the
library. When the plug is in the correct position, a click should be heard.
To connect the USB device to the library:
The USB port is on the rear of the library. It can be used for firmware upgrades/skin file updates
initiated via the operator control panel (OCP).
2.13 Verifying the host
When the host server is powered on, install the software and/or driver(s) that are compatible with the
library. Backup software packages may require additional software or licensing to communicate with
the library media changer.
To confirm that the host server’s operating system has recognized the library, consult the operating
system documentation.
2.14 Powering the library up or down
Press the power button on the front panel of the Q24 Tape Library to power it up or down. Powering
up can take a few minutes because it includes scanning the inventory and configuration (e.g. how many
and what type of drives are installed)
2.15 Tape cartridges
Before you begin using the library, an understanding of the media type, use, maintenance, and how to
properly label and write-protect your tape cartridges, will help you to prolong the life of your tapes as
well as the library.
2.15.1 Tape cartridge type
The tape cartridge types supported depend on the drive types installed. The library will support any
type of LTO data cartridge and cleaning cartridge that the installed LTO drive will support.

Some tape drives include support for both rewriteable and WORM data cartridges. Write-Once, ReadMany (WORM) data cartridges provide an enhanced level of data security against accidental or
malicious alteration of data on the tape cartridge. The WORM data cartridge can have new data
appended to the maximum full capacity of the tape cartridge, but the user will be unable to erase or
overwrite any data previously recorded to the cartridge.
2.15.2 Using and maintaining tape cartridges
cartridges are pre-recorded with a magnetic servo signal. This
signal is required in order to use the cartridge with Ultrium LTO
To ensure the longest possible life for your data cartridges follow these guidelines before using the
library:
• Use only the data cartridges that are designated for your model of the library
• Clean the tape drive when the <Clean Drive> LED is illuminated. Be sure to use only Ultrium
universal cleaning cartridges.
• Do not drop an LTO data cartridge. Excessive shock can damage the internal contents of the tape
cartridge, or the tape cartridge case itself, making that tape cartridge unusable.
tape drives.
Keep Ultrium LTO cartridges separated from strong magnetic
fields such as computer monitors, electric motors, speakers, or
X-ray equipment.
Exposure to electromagnetic energy or magnetic fields can
destroy data and the embedded servo code written on the media
by the cartridge manufacturer, which can render the cartridge
• Do not expose your data cartridges to direct sunlight or sources of heat, including portable heaters
and heating ducts.
• The operating temperature range for your data cartridges is 10 to 35º C. The storage temperature
range is -40 to +60º C in a dust-free environment in which relative humidity is always between 20
percent and 80 percent (non-condensing).
