This IBM Redbooks publication focuses on the differences introduced in AIX 5L Version 5.3 when compared to AIX 5L Version 5.2. It is intended to help system administrators, developers, and users understand these enhancements and evaluate potential benefits in their own environments. AIX 5L Version 5.3 introduces many new features, including NFS Version 4 and Advanced Accounting, and exploits the advanced capabilities of POWER5 equipped severs, such as Virtual SCSI, Virtual Ethernet SMT, Micro-Partitioning, and others. There are many other enhancements available with AIX 5L Version 5.3, and you can explore them in this book. For customers who are not familiar with the enhancements of AIX 5L through Version 5.2, a companion publication, AIX 5L Differences Guide Version 5.2 Edition, SG24-5765 is available.

The aim of this IBM Redbooks publication is to provide a technical reference for IT system administrators in organizations that are considering a migration from Sun Solaris to IBM AIX 5L-based systems. This book presents a system administrator view of the technical differences that exist and the methods that are necessary to complete a successful migration to AIX 5L-based systems. This book is designed primarily as a reference for experienced Sun Solaris 8 or 9 system administrators who will be working with AIX 5L. This book is not an AIX 5L administration how-to book for system administrators who are beginners, but rather a guide for experienced administrators who have to translate a given Solaris system administration task to AIX 5L.

"Maximize your efforts toward effective performance tuning on AIX on IBM's Power Systems (IBM i, AS/400, iSeries, System i, AIX, and Linux). With detailed information on optimizing your CPU, memory, disk, and network I/O subsystems, along with data on both AIX 5.3 and AIX 6.1, the author gives detailed instructions on how to tune your system effectively, delivering the performance boost you desire. In addition to these topics, chapters on the new AIX 6.1, Linux, and Oracle running on IBM Power Systems are included. Packed with real-world know-how from author Ken Milberg--a 20-year systems administration veteran--this book is intended for systems professionals who need to understand, monitor, and control the factors that affect AIX performance on their servers. It covers systems monitoring and performance tuning on all subsystems as well as time-tested tuning and analysis methodology. The monitoring sections discuss tools that will allow you to immediately gain a quick and dirty view of the health of your system"--Resource description page.

This IBM Redbooks publication is designed as a study guide for professionals wishing to prepare for the certification exam (Test 222) to achieve: IBM Certified Specialist eServer p5 and pSeries Administration and Support for AIX 5L Version 5.3. The certification validates a broad scope of AIX 5L administration, support, problem determination skills, and the ability to perform general AIX 5L software system maintenance. This book helps AIX 5L professionals seeking a comprehensive and task-oriented guide for developing the knowledge and skills required for the certification. It is designed to provide a combination of theory and practical experience needed for a general understanding of the subject matter. This book does not replace practical experience you should have, but is an effective tool that, when combined with education activities and experience, should prove to be a very useful preparation guide for the exam. Due to the practical nature of the certification content, this publication can also be used as a desk-side reference. So, whether you are planning to take the eServer p5 and pSeries Administration and Support for AIX 5L Version 5.3 certification exam, or if you just want to validate your AIX 5L skills, this book is for you.

Booting servers from a storage area network (SAN) is being used increasingly in complex data center environments today, due to its significant benefits over the traditional method of booting from local disks. SAN Boot enables organizations to maximize consolidation of their IT resources, minimize their equipment costs, and realize the considerable management benefits of centralizing the boot process. In SAN Boot, you can deploy diskless servers in an environment where the boot disk is located on (often RAID-capable) storage connected to the SAN. The server (initiator) communicates with the storage device (target) through the SAN using the Fibre Channel host bus adapter (HBA). The system downtime is greatly minimized in case a critical component such as a processor, memory, or host bus adapter fails and needs to be replaced. The system administrator needs to swap only the hardware and reconfigure the HBA's BIOS, switch zoning, and host-port definitions on the storage server. The system image still exists on the logical drive, therefore the server is fully operational after the hardware swap and configuration change is completed. This IBM® Redbooks® publication can help you with the SAN Boot implementation. We present various SAN Boot scenarios using IBM System Storage® products that include DS5000, DS8000®, XIV®, and SVC. The operating systems that are covered include Windows 2008, Red Hat Linux, SUSE Linux, and VMware.
