The following tools can be used for installing and updating HP-UX. For complete details on this topic, see the latest version of the HP-UX 11i v3 Installation and Update Guide.

Cold Installs

The term cold install means installing system software on a new (does not currently contain an image of HP-UX) or existing (contains an instance of HP-UX that you are willing to completely overwrite) system by completely rebuilding the root volume group, erasing the existing operating system and data on that volume, and installing the new operating system and specified software and data.

You can choose two different methods to cold-install HP-UX 11i v3 on a supported system:

  • By direct installation from the DVD media

  • By creating depots on servers using SD-UX or Ignite-UX and installing it over the network.

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.


Ignite-UX addresses the need for HP-UX system administrators to perform system installations and deployment, often on a large scale. It provides the means for creating and reusing standard system configurations. It provides the ability to archive a standard system configuration, and to use that archive to replicate systems, with the added benefit of speeding up the process. It also permits post-installation customizations, and is capable of both interactive and unattended operating modes.

  • Ignite/UX install sessions for multiple targets can be controlled from a single server in a true client/server model.

  • Installations can occur from multiple software sources in a single install session.

  • It is easy to create a system that is ready to go as soon as the install session completes.

For details on Ignite-UX, see http://docs.hp.com/en/IUX.


The update-ux command is the tool to use to update one version of HP-UX to a newer version (provided that you are using a supported upgrade path). For details on supported upgrade paths and general update procedures, see the latest version of the HP-UX 11i v3 Installation and Update Guide. For details on the update-uxcommand and its options, see the update-ux(1M) manpage.
