This document is intended to assist customers and systems engineers in understanding and utilizing storage management with AIX Version 4 on the RISC System/6000. The concepts and terminology of AIX storage management are explained first, providing a foundation for a more detailed examination of the elements involved. This will allow less experienced readers to reach the level of understanding necessary to appreciate the new features and functions provided with AIX Version 4. Examples in the use of various storage management commands are provided, as well as an overview of the issues involved in organizing and managing storage with AIX Version 4 on the RISC System/6000. In order to more effectively convey the information, a comprehensive set of detailed scenarios provide step by step practical examples.
The document is organized as follows:
This chapter describes general concepts relating to storage. It is designed
to bring those readers with little or no knowledge of storage management under
AIX to a level sufficient to appreciate the latter parts of this book. This
chapter can be skipped by those readers who already have a good grasp of
general storage management concepts.
This chapter discusses in more detail, the hardware components available for
use by AIX storage management products. Basic operation and functions are
outlined to provide a context for understanding the functions and options
provided by the storage management products. This chapter may be used as
reference to specific hardware types, or skipped by those readers who are
already familiar with the operation of all AIX hardware storage devices.
This chapter describes the operating system software components involved in AIX storage management. Specifically, the following areas are covered:
This chapter can be skipped by readers who are already familiar with these
elements of AIX storage management.
This chapter contains descriptions of all of the new features and functions
that enhance AIX storage management, as included in AIX Version 4. This
information is new, and should be read by anyone who is planning to manage
storage on a RISC System/6000 using AIX Version 4; it may be skipped by those
readers who will not be moving to AIX Version 4 at this time.
This chapter discusses the various issues involved in designing,
configuring, and managing storage under AIX Version 4 on the RISC System/6000.
This information is meant to allow readers to gain an insight into the
considerations involved in creating efficient storage resources and should be
viewed by any reader not familiar with designing efficient storage resource.
This chapter explores more practical aspects of storage management,
investigating the procedures necessary for successfully maintaining the storage
elements of a system. This chapter contains information applicable to Version 3
and Version 4 users, though readers familiar with management at Version 3 need
only look at those sections pertaining to the Version 4 enhancements.
This chapter provides examples of the usage of a variety of AIX commands for
the management of storage. The chapter is split into two sections, pre-Version
4 commands and post-Version 4 commands. Those commands included in the former
section are still relevant under Version 4, while the latter section contains
examples of new commands. Readers already familiar with Version 3 commands may
therefore wish to skip the first section.
This chapter consists of a number of practical examples of storage
management under AIX Version 4. The examples include topics such as reducing
page space utilization, common storage errors/recovery, setting backup/restore
policy, utilization of new Version 4 features, and many more. Each example
contains step by step details and explanations. This chapter should be used by
all readers for reference as required.
This appendix will provide an overview of the various hardware storage
devices available for attachment to the RISC System/6000. The emphasis is on
the basic features provided by the devices, and the mechanisms for attaching
them to the RS/6000.
This appendix contains a brief overview of the higher level storage
management products available. This redbook is primarily intended to cover AIX
Version 4 storage management, and as such this information is included for
reference only.
This appendix will provide several examples of techniques for recovering from disk failures. These examples have not been tested in this project and are presented as is.
The publications listed in this section are considered particularly suitable for a more detailed discussion of the topics covered in this document.
