Introduction
The first part of this chapter covers concepts and terms related to system
installation, the installation phases, and a summary of the types of software
configuration that can be installed. The second part of this chapter covers
the concepts and components of an over-the-network installation environ-
ment. The third part covers automating over-the-network installation using
the JumpStart feature. The last part describes using Flash Archives to speed
up the installation of a large number of identical systems.
Server Installation
This section includes the phases of an installation, the software configura-
tions that can be installed on a system, and over-the-network installation.
Installation Phases
Installation consists of three phases:
The
system configuration phase
identifies the necessary system information
➤
The
system installation phase
copies the software onto the system
➤
The
post-installation phase
updates and configures system software as
required
➤
Each of these is discussed in the following sections.
System Configuration Phase
During the system configuration phase, basic information about the system,
such as hostname and domain, is identified. This information can optionally
be set up ahead of time, or
preconfigured
. There are two methods to precon-
figure system information. The first involves using the
sysidcfg
file, and the
second involves using a
name service
.
If a system is not preconfigured, the
sysidtool(1M)
command is executed during
installation to prompt for the information. The
sysidtool
command consists of five
programs:
sysidnet
,
sysidnis
,
sysidsys
,
sysidroot
, and
sysidpm
.
