Installing And Updating: Why Do It - HP 9000 Manual

Installing and Updating: Why Do It?

One of the first questions needing to be answered when system hardware
has to be changed is: should the system undergo an update of just the
software concerned, or is it more effective and less error-prone to just
re-install the entire disk. Where the change involves a new file system
layout, as in the transition between HP-UX 9.x and 10.x, there is also the
question of whether to upgrade or re-install.
Background Ignite-UX is HP's new installation tool which has replaced the old "cold
install" toolset for installations, both for single systems and for large
replicated sites consisting of many networked systems.
At large sites, where speed of installation is crucial, Ignite-UX can install
one system whose configuration can then act as a model (with small
changes) for all later installations.
Ignite-UX can be set up so that new systems, when cold booted from the
IUX server, install a predefined default configuration without further
user intervention.
For a system being installed with Ignite-UX, the System Administrator
can execute a command from the Ignite-UX server to begin the install
process. No local intervention is required.
The System Administrator can also set up, ahead of time, config files for
existing systems. Ignite-UX will use these during install instead of the
default configuration. This can ensure that specific existing systems get
unique configurations.
