When to Cold-Install
CAUTION The cold-install process erases software on the root volume before
installing HP-UX 11i v1. 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 overwrites everything on the
target disk.
You can cold-install rather than update to HP-UX 11i v1 when:
• You have a new system.
• You are managing several systems with similar OS configurations.
• 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 v1” on page 51.
You can cold-install from any supported configuration. See “Supported
Servers and Workstations” on page 36.
See Chapter 4, “Preparing to Install or Update to HP-UX 11i v1,” on
page 63 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 v1,” on page 75.
