xiv Implementing IBM Tape in UNIX Systems

Preface

This IBM® Redbook follows The IBM TotalStorage Tape Libraries Guide for Open Systems,
SG24-5946, and will help you plan, install, and configure IBM Ultrium LTO tape drives and
libraries, as well as the IBM 3592 tape drive in UNIX® environments. This book focuses on
the setup and customization of these drives and libraries in both direct-attached SCSI and
SAN configurations for the AIX®, Solaris™, and HP-UX operating systems.

The first part of the book describes how to attach and configure the drives and libraries, and
covers basic installation and administration. It also describes the sharing and partitioning of
libraries, and explains the concept and usage of the Advanced Library Management System
(ALMS) and virtual I/O with the IBM TotalStorage 3584 Tape Library.

Part two documents how to use these products with popular data backup applications such
as IBM Tivoli® Storage Manager and EMC Legato NetWorker.

This redbook will help IBM personnel, Business Partners, and customers to better understand
and implement the IBM Ultrium LTO product line as well as the 3592 Enterprise tape drive in
UNIX environments.

We assume that the reader is familiar with tape drives and libraries, and understands basic
SAN concepts and technologies.

1.1 LTO overview
The Linear Tape-Open (LTO) program began as a joint initiative of Hewlett-Packard, IBM,
and Seagate Technology. In 1997, the three companies set out to enable the development of
best-of-breed tape storage products by consolidating state-of-the-art technologies from
numerous sources. The three companies also took steps to protect customer investment by
providing a four generation roadmap and establishing an infrastructure to enable compatibility
between competitive products.

The LTO technology objective was to establish new open-format specifications for high
capacity, high performance tape storage products for use in the midrange and network server
computing environments, and to enable superior tape product options.

The current technology provider companies are IBM, HP, and Certance LLC (owned by
Quantum), but LTO program cooperation goes beyond these three companies. LTO format
specifications have been made available to all who want to participate through standard
licensing provisions. LTO program technology has already attracted a number of other
industry leaders, so LTO-specified products (tape drives and tape storage cartridges) will
reach the market from multiple manufacturers, not just the technology provider companies.
This is critical to meeting an open market objective, and is accomplished through open
licensing of the technology.

Cooperation is also evident in the LTO program requirement that all products produced by
licensees be technically certified annually. The primary objective of this certification is to help
determine whether LTO format cartridges will be exchangeable across drives produced by
different Ultrium manufacturers. Simply stated, this means “LTO-compliant media from any
vendor can be read and written in LTO-compliant drives from any vendor.”

All three consortium members (IBM, HP, and Certance) are now shipping LTO Ultrium
products, and numerous other licensees are shipping hardware and media.

The LTO Ultrium road map (Figure 1-1) shows the evolution of LTO technology. At the time of
writing, IBM Ultrium generation 2 and 3 products are offered; however, there are many
existing installations of now-withdrawn Ultrium 1 products, so they are included for your
reference. The information in the road map is given as an indication of future developments
by the three consortium members, and is subject to change.

Important: Hewlett-Packard, IBM, and Certance reserve the right to change the
information in this migration path without notice.

Ultrium 3
The Ultrium 3 Tape Drive is compatible with the cartridges of its predecessors, the Ultrium 2
and Ultrium 1 Tape Drive. Cartridge compatibility for the Ultrium 3 Tape Drive is as follows:
Reads Ultrium 1 format on Ultrium 1 cartridges

WORM tape format
Beginning with LTO Ultrium 3, Write Once Read Many (WORM) functionality provides for
non-erasable, non-rewritable operation with tape media and is designed for long term tamper
resistant record retention.


The LTO Ultrium 3 specification for WORM includes the use of low level encoding in the
Cartridge Memory (CM) and is also mastered into the servo pattern as part of the
manufacturing process. This encoding is designed to prevent tampering.

Data can be appended at the end of a WORM cartridge to which data was previously written,
allowing the full use of the high capacity tape media.

LTO Ultrium 3 WORM cartridges can be used with any LTO Ultrium 3 tape drive with the
appropriate microcode and firmware.

LTO Ultrium 3 non-WORM-enabled and WORM-enabled drives can coexist in the same
library.
