HP-UX 11i v2 Installation and Update Guide, December 2007

Choosing an Installation Method
Deciding Which Method to Use
Chapter 350
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. Additional information on Ignite-UX and newer
versions are available at: http://docs.hp.com/en/IUX/
See Chapter 4, “Preparing to Cold-Install or Update to HP-UX 11i v2,” on
page 69 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 Using Media,” on page 85.
When to Update
You can update rather than cold-install HP-UX 11i v2 when:
• You are updating from a supported HP-UX 11i v1 or HP-UX 11i v2
system. See “Supported Update Paths to HP-UX 11i v2” on page 45
for specific details.
• You are concerned about recovering unique applications and data on
your root volume, and do not want to write over non-OS files, which
occurs when cold-installing HP-UX 11i v2.
• Each system has a unique configuration.
• Current disk space is sufficient for HP-UX 11i v2. See “How to Plan
Your Disk Space Needs” on page 33.
This installation method uses the update-ux command and Software
Distributor (SD) tools to selectively overwrite the operating system and
application software from media or a network source depot. An
advantage of performing an update is that it leaves user data,
configuration, and applications in place. Updating to HP-UX 11i v2 is
limited to the supported paths listed in “Supported Update Paths to
HP-UX 11i v2” on page 45.
See Chapter 4, “Preparing to Cold-Install or Update to HP-UX 11i v2,” on
page 69 for details on how to prepare your system to update to HP-UX
11i v2. The update process is described in Chapter 6, “Updating to
HP-UX 11i v2,” on page 103.
