When to Cold-Install
CAUTION The cold-install process erases software on all disks selected to
participate in the installation before installing HP-UX 11i v2. If you
want to retain any existing software, make sure to back up that software
before migrating or use update. Cold-installing using Ignite-UX or
media overwrites everything on the target disks.
Use Ignite-UX to cold-install HP-UX 11i v2 in the following situations:
• You have a new system.
• You are managing several systems with similar OS configurations.
• You need fast, predictable deployment.
• Your disk space needs reconfiguration. See “How to Plan Your Disk
Space Needs” on page 33.
• Your systems are organized with clean separation of the OS from
user, application, and data files.
• Overwriting the root(/) volume on existing systems will not cause a
loss of applications or data.
• Your system configuration is not listed as a supported update path.
See “Supported Update Paths to HP-UX 11i v2” on page 45.
• You are migrating an HP Itanium Workstation to HP-UX 11i v2
(PA-RISC workstations not supported.)
You can cold-install from any supported configuration. See “Supported
Servers and Workstations” on page 36.
The process described in this guide cold-installs a single system from
local media. If you plan to install many systems simultaneously, use an
Ignite-UX server. Ignite-UX is available on the HP-UX 11i v2 DVD.
Additional information on Ignite-UX and newer versions are available at
the Software Depot Web site:

See Chapter 4, “Preparing to Install or Update to HP-UX 11i v2,” on
page 71 for more information about preparing your system for
cold-install and then read the cold-install process using Ignite-UX in
Chapter 5, “Cold-Installing HP-UX 11i v2,” on page 87.
