Choosing an Installation Method
Deciding Which Method to Use
Chapter 3 53
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.
When to Update
You can update rather than cold-install HP-UX 11i v2 when:
• You are updating from a supported HP-UX 11i v1.0, HP-UX 11i v1.6,
and HP-UX 11i v2 system. See “Supported Update Paths to HP-UX
11i v2” on page 47 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 35.
NOTE Update is not supported on HP 9000 PA-RISC Workstations.
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 47.
See Chapter 4, “Preparing to Install or Update to HP-UX 11i v2,” on
page 71 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.
