HP-UX 11i v3 Installation and Update Guide, September 2010

Uninstalling HP-UX 11i v3
If you cannot resolve problems after installing HP-UX 11i v3, then you might want to uninstall
it. The process depends upon the install process you followed:
• If you previously created an operating system recovery image with either
make_net_recovery or make_tape_recovery using Ignite-UX, boot the system from
that media to return the OS and any archived applications to the previous release. See the
Ignite-UX Administration Guide available on the Instant Information DVD and at http://
www.hp.com/go/ignite-ux-docs.
• If you used a drd clone to create your system recovery image, see “Choosing drd clone”
(page 24).
• If you do not use Ignite-UX or DRD, or do not have a current operating system recovery
image:
— If your applications and data are on a separate disk from the OS, cold-install the previous
OS. Doing this ensures a clean OS installation, removing all previous upgrade and patch
information.
— If applications, data, or both are on the same volume with the OS, boot from the
previously-saved system recovery tape to return to a previous OS. These expert recovery
processes are in the Ignite-UX Administration Guide.
Removing applications and patches
To determine which applications are on the system and where they are located, use swlist. If
you only need to remove applications or patches from the system, use swremove. For details,
see the Software Distributor Administration Guide (http://www.hp.com/go/sd-docs).
Diagnostics
Now that you have installed or updated HP-UX, you can use it to keep your system running.
The diagnostics software for HP servers helps you troubleshoot and fix problems when a hardware
failure occurs.
Online diagnostics
The online diagnostics software, which is always-installed with HP-UX 11i v3, consists of two
product bundles:
• OnlineDiag (Online Diagnostics)
• SysFaultMgmt (System Fault Management [SFM])
These bundles include many tools to help verify, troubleshoot, and monitor PA-RISC and
Itanium-based system hardware such as processors, memory, power supplies, fans, interface
cards, and mass storage devices. For more information about these products, see the
documentation at http://docs.hp.com/en/diag.html.
Offline diagnostics
The Offline Diagnostic Environment (ODE) includes a set of offline support tools that enables
you to troubleshoot a system that is running without an operating system. The ODE tools are
provided on CDs for HP Integrity systems and HP 9000 systems. You can order the CDs at no
charge or you can download the CD image and burn your own CD.
For instructions on how to order the ODE CD (or download the CD image), see the Administrator's
and User's Guide for Offline Diagnostics (http://docs.hp.com/en/diag.html). Other ODE
documentation, including release notes, is available at this site as well.
HP highly recommends that you get the latest CD and update the ODE for improved functionality.
Note that the CD-ROMs are OS independent and ordered separately from each other and of any
operating system media.
