The all-in-one authorized reference for HP certified, HP-UX system administration certification!

If you are preparing for HP Certified, HP-UX System Administration certification, here's your all-in-one,
authorized reference and preparation guide! The only preparation book approved by HP Education, HP
Certified, HP-UX System Administration covers every exam objective in HP's three-part HP-UX System
Administration exam (3HO-002). Best of all, this comprehensive book won't just help you prepare for the
exam: it'll help you manage your systems for maximum efficiency today, tomorrow, and for years to come!
Coverage includes all this, and more:

• UNIX and HP-UX fundamentals: installation, startup, logins, shells, processes, file systems, and more

• Managing users, groups, and accounts

• Security, auditing, performance management, and optimization

• HP-UX networking: configuring LAN devices, IP addresses, NFS, DNS, NIS, and more

• Printing, backup, storage management, kernel patches, peripherals, and more

• Essential shell programming and job automation techniques

HP Certified: HP-UX System Administration contains detailed lists of exam objectives, summaries of key
points and challenging review questions after every chapter, plus a complete sample exam. If you run HP-
UX, this book is all you need to get certified. Even better, it's all you need to get results.





Preface
I have tried to write a book that covers all HP-UX system and networking administration concepts. The
book is divided into three parts. The first part consists of Chapters 1-11. It covers general UNIX concepts,
user commands, and shell programming. The second part of the book covers HP-UX system
administration and consists of Chapters 12-25. The third part consists of Chapters 26-36 and is dedicated
to computer networking concepts and HP-UX network administration tasks. The book is divided into these
three parts according to requirements of the HP-UX certification examination. This is also quite a logical
way to present the material to a UNIX system administrator. At the end of each chapter, you will find
chapter review questions to check your understanding of the material presented in the chapter. There are
some sample test questions under "Test Your Knowledge," which will provide you an idea of which type of
questions are going to be asked in the actual exam. I have tried to use a combination of simple and
difficult questions in this part. Answers to the review questions are provided in Appendix A, and answers to
the sample test questions are available in Appendix B.

While writing this book, I have tried to explain all system administration concepts in reasonable detail.
Many examples are presented in each section of a chapter to help the user understand what happens
when a particular command is executed. Commonly used command-line switches are also listed wherever
appropriate. You will also find many screen shots showing what happens when you select a menu or
press a button in the GUI windows. I have also tried to explain each system and network administration
task using both command-line utilities and System Administration Manager (SAM). Most "old-fashioned"
people would like to carry out many tasks using the command-line interface, which is also very important

for passing the HP-UX certification examination.

The book is organized such that it progresses from simple-to-understand concepts to more-difficult and
complicated ones. The same strategy is also implemented in each chapter. Figures, tables, and examples
are presented wherever helpful to communicate the concept. The first few chapters contain more
examples than the later ones to give a user a good start.

Another consideration in the organization of the book is logical relevance and order of the chapters. If an
idea or concept depends on another concept, it is placed later in the book.

This book is intended to be the most comprehensive book on HP-UX. It not only covers the HP-UX
certification exam, but it also serves as a reference book for even the most experienced HP-UX system
administrators. The first part is designed with the most basic concepts so that anybody who is new to HP-
UX can get the full benefit. The next two parts cover more-complicated system and network administration
tasks. Both novice and experienced users will find interesting things here.

Part 1: Fundamentals of UNIX Systems

The first part is an introduction to the UNIX system. This is a more-general UNIX part and consists of login
and logout procedure, file and directory manipulation, file editing, an introduction to the POSIX shell, and
file security/permissions. This part shows the concepts of users and groups, which are common to all
UNIX systems. UNIX commands related to all these topics are presented and the more commonly used
options of these commands are discussed. This part also throws light on standard input/output and I/O
redirection. Chapters 10 and 11 introduce shell programming concepts. Here you will find a number of
shell programs, up to elaborate shell variables and flow control structures.

Part 2: HP-UX System Administration

The second part is the core HP-UX system administration part of the book. It fully covers all issues from
the installation of HP-UX to managing devices, security, and system performance. The part starts with an
introduction to System Administration Manager (SAM), which is a comprehensive HP-UX tool meant for
system administration. Installation of HP-UX on a server or workstation is presented next. After that, you
will gradually progress from basic to more-complex system configuration tasks, building a kernel,
managing devices, adding/removing users, and concepts of the HP-UX file system.

Part 3: HP-UX Network Administration

The third part covers HP-UX network administration. It also contains general networking concepts such as
the ISO-OSI reference model and TCP/IP networking. One chapter is dedicated to ARPA/Berkeley
services. Then NFS, NIS, DNS, and NTP are covered.

How to Register for the HP-UX Certification Examination

You can register for the examination by calling Sylvan Prometric at 1-800-755-EXAM or directly at
Website http://www.2test.com. You can also visit an authorized Sylvan Prometric Testing Center to get
more information. A list of authorized testing centers is available at http://www.2test.com. More information
is available on the HP Education Website http://education.hp.com.

Strategies for Taking the Test

You should take a practice test to estimate the time needed to answer all questions. Stay relaxed and
have a good night's sleep before the test day. Keep the following things in mind for a successful
examination:

• Reach the testing center at least 15 minutes before the scheduled starting time. You have to sign a

for the disk drive as its argument. Let's see the output of the command shown here.

$ pvdisplay /dev/dsk/c2t5d0
--- Physical volumes ---
PV Name /dev/dsk/c2t5d0
VG Name /dev/vg00
PV Status available
Allocatable yes
VGDA 2
Cur LV 2
PE Size (Mbytes) 4
Total PE 1023
Free PE 868
Allocated PE 155
Stale PE 0
IO Timeout (Seconds) default
$

From this output, you get the following information about a physical volume.

• The volume group name to which this disk is related is vg00.

• Currently it has space allocated to two logical volumes.

• The physical extent size is 4 Mbytes.

• The total number of PEs on this disk is 1023.

• Out of 1023 PEs, 155 are allocated to volume groups, and 868 are free. The free PEs can be
allocated to a logical volume when its size is extended or to create a new logical volume.

Let's take a more-detailed listing of the physical volume by using the -v option with the pvdisplay
command as follows.

$ pvdisplay -v /dev/dsk/c2t5d0
--- Physical volumes ---
PV Name /dev/dsk/c2t5d0
VG Name /dev/vg00
PV Status available
Allocatable yes
VGDA 2
Cur LV 2
PE Size (Mbytes) 4
Total PE 1023
Free PE 868
Allocated PE 155
Stale PE 0
IO Timeout (Seconds) default

--- Distribution of physical volume ---
LV Name LE of LV PE for LV
/dev/vg00/lvol4 75 75
/dev/vg00/lvol8 80 80

--- Physical extents ---
