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 the new installation tool from HP which has replaced
the old "cold install" toolset for installations, both for single
systems and for large replicated sites consisting of many networked
systems.
A number of installations tasks are possible, using Ignite-UX:
"Pull" or "push"
install from Ignite-UX server via network.
"Push" re-install to many replicated
systems from server.
Re-install/Recovery of a damaged system.
Recovery of a corrupt root disk.
Ignite-UX provides several advantages over the previous Cold
Install product:
At large sites, where speed of installation
is crucial, Ignite-UX can install one system whose configuration
can then act as a model for all later installations.
The user interface employs tabbed dialogs to allow
more configuration capabilities. In addition, a wizard mode is available
for additional guidance.
Loads can occur from multiple software sources
in a single install session. For example, you can install a base
operating system from one SD depot, a set of patches from another
depot, and applications from a third depot, all in one session.
Ignite-UX can be set up so that new systems, when cold- booted
from the Ignite-UX server, can install a predefined default configuration
("golden disk") without further user intervention.
Moreover, for a system being re-installed with Ignite-UX,
the install process can be initiated from the server with no local
intervention at the client system.
The System Administrator can also set up configuration files
ahead of time 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.
Install Scenarios
This manual presents a number of scenarios which will help
you to follow the following procedures:
Updating your current OS and applications.
This involves using the SD-UX tools to install SD-packaged products
and bundles onto your existing system. It can serve to either update
the OS or other software, while leaving data files untouched. If
you need to upgrade from 9.0x, please
see the manual Upgrading from HP-UX 9.x to 10.01.
Installing a system from media. This is usually
done with single or few standalone systems, using a CD-ROM source.
Installing a system from a network ("pull" from
a client). This is done with a small networked site (fewer than
50 clients and few servers), and may or may not use a standard system
image.
Installing a number of systems from a network ("push"
from a server). This is done where there are many client systems
and they all generally require a similar installation. This may
use a standard system image, or "golden disk".
Re-installing a number of systems from a network
server. This is done where the client systems are to be "updated"
and their data is kept on separate servers, so that only the OS
and minimal system information need to be re-installed. This may
also use a standard system image, or "golden disk".
Building a recovery system for the target. This
can be done while you are in an install session.
Other "mixed scenarios" are also possible. For information
on upgrading a system from HP-UX 9.x, see the manualUpgrading from HP-UX 9.x to 10.x (HP Part No. B3782-90073).
The following Task-Information Roadmap will help you find
information on the main installation tasks you are likely to encounter.
