Updating and Installing: 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 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:

• Install from media.

• “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.
