Planning Your New Installation

New features, component software, and recent changes for your new system are described in the Release Notes for your new system, located in /usr/share/doc. All the media delivery for the release is on CD ROM. The HP-UX Instant Information CD in your media kit contains all the system administration and user documents which you will need.

Media for the Release

Only the Install/Core OS Software: Hardware Extensions CD is required for the OS installation, but the IPR/Diagnostic Media CD is also recommended, as it contains the Quality Pack bundle, which also has the Y2K patch bundle:

CD-ROMs Used in Installation:

Install/Core 10.20 HWE 3.0.
IPR/Diagnostic Media 4/99.Contains Hardware Enable / Critical Patch Bundle, with the Y2K patch bundle as of 4/99.
HP-UX Application Software. (4 CDs)
10.x/11.0 Extension Media ("Extension Pack").
HP-UX Instant Information.

Note that the most recent Y2K patch bundles can be obtained from the HP Y2K web site accessible from: www.software.hp.com.

Installation Tasks

During the HP-UX 10.20 installation process, you will need to do the following:

Connect and test devices.
Boot a minimal operating system from media (or a network).
Install software products from tape, CD-ROM, or network.
Execute HP-UX commands.

Some of these tasks may require previous experience or the availability of a system administrator.

Before you begin the install process, you should be prepared to enter some information as part of the process (especially if you are installing any part of the OS and applications from a network source). The process may ask for such information as the following:

The hostname of the (new) system on which you are installing HP-UX.
The local host's Internet Protocol (IP) address.
Default routing Internet Protocol (IP) address.
The subnet mask (for example, 255.255.248.0 or 0xfffff800).
The IP address of an install server (if used).

If you have a DHCP server available, the network information can be provided automatically. See Appendix B “Configuring for a DHCP Server ”

After you have installed the 10.20 operating system, you will use other HP-UX tools, utilities and scripts to set up windowing, networking, printing, mail, etc. This document does not cover these post-installation activities. For further information on these tasks, see the manual System Administration Tasks (HP Part No. B2355-90079).

What is a Cold Install?

A cold install is performed when your new system does not come with a pre-loaded operating system, or when a system is corrupted and you want to start over with a new HP-UX 10.x system.

If you purchased your system with the HP-UX Instant Ignition option, a version of HP-UX has already been installed, according to the specification in your order. You do not need to reinstall it unless you want to make changes in the disk layout.

The Installation Process

This HP-UX installation procedure is similar to that used for previous versions of HP-UX 10.x. During the cold install process, an install kernel is booted from the HP-UX Install Media (see below) or from a server on the network (Workstations (Series 700) and certain Servers (Series 800) only). Your system disk is then initialized and the new system configured using a set of default configurations supplied on the Install Media. You can either use one of these default configurations or create your own custom configuration. Once the configuration and initialization is complete, a new full-functioned HP-UX operating system and applications are loaded from the HP-UX 10.20 media (or from the network) onto your system disk.




	CAUTION: A cold install will erase all existing data on the target disk(s) during the process.

The HP-UX 10.20 cold install process is similar for all current HP 9000 computer platforms. See the flow chart Figure 1-1 “The Cold Install Process” which outlines the process.

Figure 1-1 The Cold Install Process

Each of the steps in the diagram is explained in Chapter 2. See also the Quick Guide to Installing HP-UX 10.20, which came with your HP-UX media.

The HP-UX 10.20 Install Media

The Install program software is a single, self-contained volume on CD-ROM (combined with the HP-UX core) which contains the following Install items:

Lif File Purpose

ISL: The initial system loader.
HPUX: A secondary loader.
AUTO: The auto-boot file.
CONFIG: The file that describes the default system configurations which you can specify.
INSTALL: The install kernel.
INSTALLFS: Install RAM File System.
INSTCMDS: A compressed tar-archive containing the commands used during the install process in the RAM-FS.
SYSCMDS: A compressed tar-archive containing the mini-system that is extracted prior to running the SD-UX software management commands.

The following Lif files relate to system recovery: ERECOVERY, ERECOVERFS, RECCMDS, and LOADCMDS. See the Release Notes on your system (/usr/share/doc) for the list of other patches and components on your Install and Core CD.

There are separate CD-ROMs for HP Workstation (Series 700) and Server (Series 800) hardware. For both, the delivery medium is CD-ROM, except for certain custom deliveries. (Series 700 can also generally boot over a network).




	NOTE: The ability to load the 10.20 install kernel from a network source is not available on HP Server (Series 800) computers. For these computers, you must load the install kernel from the physical media. You can, however, then install server OS and application products from a network SD-UX server, once the install kernel has been loaded from local media.

The HP-UX Product Media

The product media for the "Install and Core" HP-UX product consists of a CD-ROM containing both the Install program and the Core HP-UX product. The CD contain all the bundles, products and filesets, both required and optional, for a fully functional system. See “Using Software Bundles ” in this chapter for more information on this software. If you are using optional networking products on additional media, please see also “Networking Products on Additional Media”, in Chapter 3 “Updating from HP-UX 10.x to 10.20” in this manual.

A display listing of 10.20 bundles, products, and contents can be obtained by running swlist on your source depot (disk, CD-ROM, tape, or network). See Chapter 3 “Updating from HP-UX 10.x to 10.20” for instructions on using swgettools to update the SD-UX tools first, if the source is a new version of HP-UX.
