Deciding Which Method to Use

Now that you have evaluated your system and ordered any additionally needed hardware, you need to decide whether to cold-install or update to HP-UX 11i v2 on your system.

Cold-installing using Ignite-UX — This method overwrites everything on the target disk. Use cold-install for new systems and on existing systems when overwriting the root (/) volume will not cause loss of applications or data. The process described in this guide cold-installs a single system from local media. If you plan to install many systems simultaneously, you should plan on using an Ignite-UX server. Ignite-UX is available on the HP-UX 11i v2 DVD. Additional information on Ignite-UX and newer versions are available on this web site:

http://software.hp.com/products/IUX

Updating using Update-UX — This 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 Table 2-1 “OE Update Migration Paths to HP-UX 11i v2”.

Depending on your system’s current configuration, here are some general guidelines to help you choose the best migration path to HP-UX 11i v2.

When to Cold-Install

We recommend using Ignite-UX to cold-install HP-UX 11i v2 in the following situations:

You are managing several systems with similar OS configurations.
You need fast, predictable deployment.
Your disk space needs reconfiguration. See “How to Plan Your Disk Space Needs” on page 55.
Your systems are organized with clean separation of the OS from user, application, and data files.
Your system configuration is not listed as a supported update path (see Table 2-1, “OE Update Migration Paths to HP-UX 11i v2,” on page 34).
You are migrating an HP Workstation to HP-UX 11i v2.

You can cold-install from any supported configuration (see “Supported Servers and Workstations”).

See Chapter 4 “Preparing to Migrate to HP-UX 11i v2” for more information about preparing your system for cold-install. Then the cold-install process using Ignite-UX is described in Chapter 5 “Cold-Installing HP-UX 11i v2”.

When to Update

You can update rather than cold-install HP-UX 11i v2 when you are updating from supported HP-UX 11i v1.6 systems or from HP-UX 11i v2 (see Table 2-1 “OE Update Migration Paths to HP-UX 11i v2” for specific details). Other scenarios include:

You are concerned about recovering unique applications and data on your root volume, and do not want to write over non-OS files 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 55).




	NOTE: Update is not supported on HP Workstations.

See Chapter 4 “Preparing to Migrate to HP-UX 11i v2” for details on how to prepare your system to update to HP-UX 11i v2. Then the update process is described in Chapter 6 “Updating to HP-UX 11i v2”.

Installing Network Drivers

Installing HP-UX 11i v2 will install a minimum set of default networking drivers that apply to the system (see Table D-4 “HP-UX 11i v2 Always-Installed Network Drivers”).

You may need to select or specify other available networking drivers to enable other cards on your system (see “HP-UX 11i v2 Always-Installed Network & Mass Storage Drivers”). This can easily be done during the cold-install or update by following the instructions in “Cold-installing HP-UX 11i v2”.

Cold-Install Considerations

The following sections provide additional information to assist you in your decision to cold-install HP-UX 11i v2.

HP Service Partition

During cold-install or recovery, Ignite-UX will change the boot disk partition layout to create a new HP Service Partition (HPSP). This 400MB partition created at the end of the boot disk is used by Online and Offline Diagnostics to hold tools and system data.

The order of the partitions on the boot disk will be:

EFI OS Boot Partition (ESP)
HP-UX File System (HPUX)
HP Service Partition (HPSP)

During back-up and recovery operations, Ignite-UX will not save or restore any changes you make to the HPSP.

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. See Chapter 8 “Installing Patches and Applications”.

Alternate Cold-Install Methods

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

Install 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.
Install 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.




	IMPORTANT: Please note that if you are running an Ignite-UX server on HP-UX 11i v2 and have HP-UX Bastille enabled, then cold-installing a golden image onto another system will require additional steps.

Using the HP-UX 11iv2 DVDs on an HP-UX 11iv1 (B.11.11) System

If you plan to read the HP-UX 11iv2 DVDs on an HP-UX 11iv1 system, or cold-install HP-UX 11iv2 from a depot on an HP-UX 11iv1 system, then you need to install the PHKL_28025 patch in order to read the DVDs.

The PHKL_28025 patch is in the GOLDBASE11i bundle as of June 2003, which you can find on the Support Plus media for HP-UX 11iv1 or at the following web site:

http://itrc.hp.com

PHKL_28025 supersedes PHKL_25760.

Update Considerations

HP Service Partition Is Not Created During Update

If you are updating from a supported update path (see “Supported Update Paths to HP-UX 11i v2”), HP Service Partition will not be created or modified. OnlineDiag will continue to work properly. Offline Diagnostics, however, will work with reduced functionality.

In order to have full Offline Diagnostics functionality, you must:

Update your system.
Back up your system with either make_net_recovery or make_tape_recovery.
Re-configure your boot disk partition layout to include the HP Service Partition.
Restore your system with either make_net_recovery or make_tape_recovery. Consult the Ignite-UX Administration Guide for more details about make_net_recovery and make_tape_recovery.
Update the Offline Diagnostics with the latest version of the HP Itanium-Processor Family Offline Diagnostics and Utilities CD. See “About Offline Diagnostics” on page 71.

How to Determine If You Have an HP Service Partition. To determine if an HP Service partition exists on your system, enter the following command on your physical disk volume (here named /dev/rdsk/c2t1d0):

idisk -p /dev/rdsk/c2t1d0

Example 2-1 idisk Output from Disk without HP Service Partition

idisk version: 1.31

        HeaderSize                = 0x5c
        HeaderCRC32               = 0x20e10a24
        MyLbaLo                   = 0x1
        AlternateLbaLo            = 0x43d671f

        PartitionEntryLbaLo       = 0x2
        NumberOfPartitionEntries  = 0xc
        SizeOfPartitionEntry      = 0x80
        PartitionEntryArrayCRC32  = 0xc0a93cc2
 
Primary Partition Table (in 512 byte blocks):

        Unique Partition GUID     = 5960a1be-c295-11d7-8002-d6217b60e588
        Starting Lba              = 0x22
        Ending Lba                = 0xfa021
    Partition 2 (HP-UX):
        Partition Type GUID       = 75894c1e-3aeb-11d3-b7c1-7b03a0000000
        Unique Partition GUID     = 5960a1fa-c295-11d7-8003-d6217b60e588
        Starting Lba              = 0xfa022
        Ending Lba                = 0x430e02

You should notice that under the “Primary Partition Table (in 512 byte blocks)” heading, only two partitions exist on the system: the EFI boot partition, and the HP-UX partition. This example shows that you will need to create the HP Service Partition after updating to HP-UX 11i v2.

Default-Installed Bundles Cannot Be Deselected

There is currently no support for deselecting default-installed bundles (see Appendix D “Software Distribution Media”) from Update-UX. Consequently, all default-installed bundles will be installed with the Operating Environment.
