You may want to build customized install media if:
You have a large number of systems
that are basically identical, and:
The systems do not have network boot
capability, or...
The networking will not allow easy or fast access
to an Ignite-UX server, or...
The systems are geographically widespread.
You have HP servers that lack network boot, and
so a boot medium is required to contact the Ignite-UX server.
You want to deliver media to a technician or operator
and have the entire install process automated without human intervention
or interaction.
You want a single media that contains all the desired
parts of the operating system (HP-UX, applications, patches, diagnostics
and local customizations).
Using customized install media also provides both system standardiza- tion
and customization simultaneously. The standardization comes from using
golden system images which contain a base operating system, applications,
patches, third-party software and local customizations, already
packaged into an archive. The entire system has been tested, verified
and tuned before creating the image. This image can be the starting
point for all installs to ensure standardization.
The customization comes from using config files to load additional software,
change kernel parameters, and run scripts. Software bundles can
be:
Pre-selected, unconditionally or conditionally.
There are also parameters that control the environment in
which Ignite-UX operates. The most important parameters are run_ui and control_from_server. When run_ui is false, no interaction will occur and the load
will proceed according to all the configuration information provided
to Ignite-UX. When control_from_server is true, an attempt will be made to contact the
Ignite-UX server as defined in the configuration information. These
modifications are explained in the procedures in this chapter.
Using a custom install media allows you to chose how things
work, what you will leave up to the end user, what will happen automatically,
and so forth.
Building
Example Install Media |

The remainder of this chapter describes building custom install
media that meets these requirements:
It will be shipped worldwide so that
systems can be installed with a golden image.
Both a Series 700 workstation and a Series 800 server
golden images will be built with the make_sys_image command.
There is a set of applications that are to be chosen
interactively by the end user.
All software will come from the media, and there
will be no contact with nor need for an Ignite-UX server during
installation. However, you do need an Ignite-UX server to create
the media and execute Ignite-UX commands.
