Deciding Which Method to Use

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 or update it.

Cold-install means installing system software on a new (un-installed) or existing system disks by completely rebuilding the volume group (see “Back up Your 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, configuration, 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.




	CAUTION: If the Distributed File System (DFS) is installed and in use on your HP-UX 10.20 system to manage large numbers of files, update-ux will remove it and associated data during the update to HP-UX 11i. If you need to continue using DFS, do not update to HP-UX 11.x or HP-UX 11i.

Depending on your system's current configuration, here are some general guidelines to help you choose the best migration path to HP-UX 11i.

Cold Install When...

We recommend using Ignite-UX to cold-install HP-UX 11i in the following situations:

You are managing several systems with similar OS configurations.
You need fast, predictable deployment.
Your disk space needs reconfiguration. See “Planning Your Disk Space Needs”.
Your 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 Table 3-1 “Supported Systems”.)

The cold-install process using Ignite-UX is described in Chapter 5 “ Cold Installing HP-UX 11i”. “Preparing to Cold-Install Your System” for more information.

Update When...

You can update rather than cold-install HP-UX 11i when you are updating from HP-UX 10.20 or 11.0 as well as the following:

You are only updating a few (1-3) systems to HP-UX 11i.
You are concerned about recovering unique applications and data on your root volume, and do not want to write over non-OS files when installing HP-UX 11i.
Each system has a unique configuration.
Current disk space is sufficient for HP-UX 11i (see “Planning Your Disk Space Needs”).




	NOTE: update-ux removes all HP-UX 10.x patches from the system prior to updating to HP-UX 11i. Any 10.x applications left on the system after the update may not be supportable if they required those patches. After migrating your system, consult the documentation for those remaining applications for HP-UX 11i requirements.

If your system meets these requirements, follow the update procedure in Chapter 6 “Updating to HP-UX 11i”. “Preparing to Update Your Existing System” for more information about preparing to update your system.

Additional Considerations (Cold-install or Update)

Firmware Patches Should Not Be Included Cold-Install or Update Session

If you are migrating from either HP-UX 10.20 or HP-UX 11.0, HP strongly recommends you do not include firmware patches while running a cold-install or update session.

How Do You Know If This Affects You?

The following systems are affected:

A-Class
L-Class
N-Class

Many of the HP-UX 11i firmware patches rely on HP-UX 11i tools and system calls. The cold-install or update process uses a subset of existing commands and system calls. The firmware installation fails because of system call differences between the HP-UX 11i operating system and the install session version.

What To Do:

HP strongly recommends that you install any firmware patches after you have completed the cold-install or update process and your system is running HP-UX 11i. Specific HP-UX 11i firmware patches are available at the following website:

http://itresourcecenter.hp.com

MLIB Temporarily Removed from TCOE Operating Environment

With the December 2002 release of HP-UX 11i, MLIB was temporarily removed from the OE media. A supplemental CD-ROM has been provided and instructions for installing or updating MLIB can be found in “Installing MLIB (TCOE Customers)”

Updating Network Drivers

Installing or updating to HP-UX 11i will install a minimum set of default networking drivers that apply to the system (see Table 4-1 “HP-UX 11i Software Bundles and Descriptions ”). You may need to select or specify other available networking drivers to enable other cards on your system (see Table 4-2 “HP-UX 11i Selectable Drivers ”). This can easily be done during install or update by following the instructions for your selected migration path.

Installing or updating HP Apache-based web server

If your system already is running any version of the HP Apache-based Web Server, installing or updating to an HP-UX 11i Operating Environment will not install the version of Apache included with the HP-UX 11i OE. If you wish to install the version of Apache provided with HP-UX 11i, you should swinstall it after migrating your system to HP-UX 11i. See Chapter 8 “Updating Applications” for example uses of the swinstall command.

Installing or Updating Netscape Directory Server

Although the Netscape Directory Server (NDS) Version 6.02 is included in HP-UX 11i OEs, you must explicitly select NDS during the install or update process. If you do not select NDS, it will not be installed with HP-UX 11i. For more on this, see “Updating Netscape Directory Server”.




	CAUTION: If you have NDS version B.02.00.05 and are updating to HP-UX 11i, be sure to either select the new version of NDS during the update or remove the old version from your system. If you run NDS version B.02.00.05 with HP-UX 11i, the server will cease to work and all client systems may lose the ability to have anyone log in.




	NOTE: Currently, Netscape Directory Server Version 6.02 is included with the HP-UX 11i Operating Environments. If you wish to have the iPlanet 5.0 product, order the AR1202 CD or DVD for this product separately.

After NDS is installed or updated with HP-UX 11i, additional configuration steps are required to initiate NDS. See the NDS release notes available on the HP-UX 11i Instant Information CD for instructions.

HP 3D Graphics No Longer Supported pre-PA-RISC 2.0 Systems

As of the September 2002 HP-UX 11i release, HP 3D Graphics are no longer supported on PA-RISC systems older than version 2.0. If you have an older PA-RISC workstation and need 3D Graphics, HP recommends that you do not install or update to the this release of the Technical Computing (TCOE) or Minimal Computing Operating Environments (MCOE).

Previous releases of HP-UX 11i still support PA-RISC 2.0 and older systems. If you have any questions about your particular situation, please contact your local HP Country Response Center.

How to Determine Your PA-RISC Version . With the System Administration Manager (SAM), select: Performance Monitors > System Properties. Your PA-RISC version will appear next to the CPU Version line.

Update Considerations

The following sections provide additional information to assist you in your decision to update to HP-UX 11i:

Updating from an HP-UX 11i TCOE With MLIB

Due the the temporary removal of MLIB software from the the TCOE operating environment media, if you are updating your system from a previous or current version of the HP-UX 11i TCOE operating environment, you will need to remove MLIB prior to installing MLIB from the HP Math Library (MLIB) supplemental CD. For more information, please review the update procedures in Chapter 6 “Updating to HP-UX 11i” and “Installing MLIB (TCOE Customers)”.

VxVM Rootability Not Enabled with update-ux

With the September 2002 release of HP-UX 11i, you can not enable VxVM rootability through the update process using update-ux. If you wish to manage your root volume with VxVM, you can choose to either enable rootability by:

cold-installing HP-UX 11i, see “Using VxVM Rootability”
using the VxVM conversion tools provided in the Base-VXVM and FEATURE11-11 bundles that are installed with HP-UX 11i (for more information about HP-UX 11i software bundles, see “What is Installed with HP-UX 11i?”). For more information, see the VERITAS Volume Manager 3.5 Release Notes and VERITAS Volume Manager 3.5 Administrator's Guide on the Instant Information CD

Updating to 64-bit OS

update-ux defaults to the OS word-width that your system is currently running. For example, if the target system is running 32-bit OS, this will be the default for the new OS to be installed.




	NOTE: Changing an existing 64-bit OS to 32-bit is not supported. To return a 64-bit OS to 32-bit, use the Ignite-UX make_tape_recovery or make_net_recovery command to restore the 32-bit OS.

Updating considerations and workarounds

You can update a system from 32-bit OS to 64-bit OS while updating to HP-UX 11i, provided that you consider these hardware and firmware issues:

Is your system capable of running 64-bit operation? See Table 3-1 “Supported Systems” in Chapter 3 “Install/Update System Requirements”.
Is your system's firmware recent enough to support 64-bit operation? See “Firmware Requirements” in Chapter 3 “Install/Update System Requirements”.
64-bit binary data cannot be used by 32-bit applications. 64-bit is useful if you need large address space, such as for use with very large databases and large-scale modeling. 64-bit applications can be compiled and linked on 32-bit systems; however, these applications cannot be run on a 32-bit system.
If updating an existing HP-UX 11i system from 32-bit to 64-bit OS, do not include the HP-UX 11i Quality Pack (GOLDQPK11i) bundle in the update-ux command. Doing so may cause a mk_kernel failure. Instead, install the GOLDQPK11i bundle from the Support Plus CD using swinstall after updating to this release.
If updating an HP-UX 10.20 system with the CDE Spanish language keyboard enabled: After updating from HP-UX 10.20 to HP-UX 11i, changing from 32-bit to 64-bit OS and installing the HP-UX 11i Quality Pack (GOLDQPK11i) bundle, you must install patch PHSS_23644 to re-enable the CDE Spanish language keyboard. Obtain this patch from the HP IT Resource Center (http://itrc.hp.com). This problem does not occur with other languages.
If updating an existing HP-UX 11i system having any of the following EISA network drivers installed, you must remove all EISA drivers before updating from 32-bit to 64-bit OS:
- 100BaseT-00 — EISA 100BaseT
- FDDI-03 — EISA FDDI
- TermIO-01 — EISA MUX
- TokenRing-02 — EISA Token Ring
(New drivers installed by default are listed in Table 4-1 “HP-UX 11i Software Bundles and Descriptions ”. Other drivers can be specified in the update-ux command or installed later using swinstall.)
To determine if any EISA drivers are installed on the system, use swlist. For example:
/usr/sbin/swlist -l bundle 100BaseT-00 FDDI-03 \ TermIO-01 TokenRing-02
If any EISA drivers are on the system, remove them. For example, to remove the TermIO-01 EISA MUX driver, as root enter:
/usr/sbin/swremove -x autoreboot=true TermIO-01
The kernel will automatically regenerate and the system will reboot after you remove each driver. After removing all EISA drivers, proceed to update as explained below.

If you're updating from HP-UX version 11.0 or higher, update-ux will determine if your hardware and firmware are compatible with 64-bit operation. If you're updating from HP-UX version 10.20, however, refer to the Software Transition Kit available on the HP-UX Applications media. The STK contains tools and documents to assess applications or libraries that run on HP-UX 10.20 and 11.0 and help transition them to the HP-UX 11i 64-bit operation. The ITRC web site (http://www.itresourcecenter.hp.com/) also has release notes and a FAQ with details about supported systems and necessary firmware updates.

Cold-Install Considerations

The following sections provide additional information to assist you in your decision to cold-install HP-UX 11i:

Using VxVM Rootability

Ignite-UX now provides you the option to install and configure VxVM 3.5 on your root volume. If you plan to configure your root volume with VxVM 3.5, make sure you read the supporting VxVM 3.5 documentation included on the Instant Information CD. For additional information, see “VxVM Rootability”

Cold-Installing on Partitioned Systems

HP-UX must be installed on the boot disk assigned to each partition after the partition has been configured. Configuring the boot disk is explained in the HP System Partitions Guide manual, available on the HP-UX 11i Instant Information CD and on HP's user-documentation web site:

http://docs.hp.com

Once each partition has been configured for installation, follow the cold-installation instruction on the following pages to install HP-UX on each partition's boot disk.

Instant Ignition

For customers ordering new systems with the "Instant Ignition" option (also known as "factory integrated"), the cold-installation process described here has already been performed. Skip this chapter and proceed to install application software.

Alternate Cold-Install Methods

In addition to the procedures described in this chapter, you can cold-install your system using the following methods:

Installing From Software Depots

Use Software Distributor commands to create depots containing OS, OE, and other software bundles, then install from the depot using Ignite-UX. For help with this method, see the swinstall(1M) manpage and Software Distributor Administration Guide and Ignite-UX Administration Guide.

Installing from Golden Images

If you need to install the same OS/OE and applications on many systems in your network, use an Ignite-UX server as explained in the Ignite-UX Administration Guide. With Ignite-UX, you can create a single install image (golden image) containing OS/OE bundles, application bundles and patch bundles, then install the image on multiple systems in your environment.
