System Administration Guide: Devices and File Systems

About This Book

System Administration Guide: Devices and File Systems is part of a set that includes a significant part of the Solaris^TM system administration information. This guide contains information for both SPARC® based and x86 based systems.

This book assumes you have completed the following tasks:

Installed the SunOS 5.11 Operating System
Set up all the networking software that you plan to use

For the Solaris Express releases, new features of interest to system administrators are covered in sections called What's New in ... ? in the appropriate chapters.

Note –

This Solaris release supports systems that use the SPARC and x86 families of processor architectures: UltraSPARC®, SPARC64, AMD64, Pentium, and Xeon EM64T. The supported systems appear in the Solaris 10 Hardware Compatibility List at http://www.sun.com/bigadmin/hcl. This document cites any implementation differences between the platform types.

In this document these x86 terms mean the following:

“x86” refers to the larger family of 64-bit and 32-bit x86 compatible products.
“x64” points out specific 64-bit information about AMD64 or EM64T systems.
“32-bit x86” points out specific 32-bit information about x86 based systems.

For supported systems, see the Solaris 10 Hardware Compatibility List.

What Typographic Conventions Mean

The following table describes the typographic conventions used in this book.

Table P–1 Typographic Conventions


Typeface or Symbol	Meaning	Example
`AaBbCc123`	The names of commands, files, and directories; on screen computer output	Edit your `.login` file. Use `ls` `-a` to list all files. `machine_name% you have mail.`
`AaBbCc123`	What you type, contrasted with on screen computer output	`machine_name%` `su` `Password:`
`AaBbCc123`	Command-line placeholder: replace with a real name or value	To delete a file, type `rm` `filename`.
AaBbCc123	Book titles, new words or terms, or words to be emphasized	Read Chapter 6 in User's Guide. These are called class options. Do not save changes yet.

Shell Prompts in Command Examples

The following table shows the default system prompt and superuser prompt for the C shell, Bourne shell, and Korn shell.

Table P–2 Shell Prompts


Shell	Prompt
C shell prompt	`machine_name%`
C shell superuser prompt	`machine_name#`
Bourne shell and Korn shell prompt	`$`
Bourne shell and Korn shell superuser prompt	`#`

General Conventions

Be aware of the following conventions used in this book:

When following steps or using examples, be sure to type double-quotes ("), left single-quotes (`), and right single-quotes (') exactly as shown.
The key referred to as Return is labeled Enter on some keyboards.
The root path usually includes the /sbin, /usr/sbin, /usr/bin, and /etc directories. So, the steps in this book show the commands in these directories without absolute path names. Steps that use commands in other, less common, directories show the absolute paths in the examples.
The examples in this book are for a basic SunOS software installation without the Binary Compatibility Package installed and without /usr/ucb in the path.

Caution –
If /usr/ucb is included in a search path, it should always be at the end of the search path. Commands such as ps or df are duplicated in /usr/ucb with different formats and options from the SunOS commands.
