Selecting the Path to HP-UX 11i

Now that you have evaluated your system and ordered any additional
needed hardware, you need to decide whether to cold-install HP-UX 11i
on your system (overwrite everything on the root disk) or update it
(replace the OS, patches and add an OE, while leaving other applications
intact).
Cold-install means installing system software on a new (un-installed)
or existing system disk by completely rebuilding the root file system,
erasing the existing operating system and data on that volume and
installing the new operating system and specified software and data. An
advantage of cold-install is that supported software can be installed
without regard for the software currently on the system, or concern for
cleaning up old software.
Update means using the update-ux command and Software Distributor
(SD) tools to selectively overwrite the operating system and application
software from a media or network source depot. An advantage of
performing an update is that it leaves user data, configurations and
applications in place. Updating to HP-UX 11i requires that the system be
running at 10.20 or 11.0, with or without extension or Additional Core
Enhancement (ACE) packs installed.
Here are some general guidelines:
We recommend using Ignite-UX to cold-install HP-UX 11i when:
• You are managing several systems with similar OS configurations.
• You need fast, predictable deployment.
• Disk space needs reconfiguration. See "Needing More Disk Space?" on
page 26.
• Systems are organized with clean separation of the OS from user,
application and data files.
You can cold-install from any supported HP-UX OS. See the table on
page 17.
The cold-install process using Ignite-UX is described in Chapter 2.
