Uninstalling HP-UX 11i v2
If you cannot resolve problems after installing HP-UX 11i v2, then you
may want to un-install it. The process depends upon the install process
you followed:
•If you made a make_tape_recovery tape using Ignite-UX, boot the
system from that media to return the OS and any archived
applications to the previous release. Refer to the Ignite-UX
Administration Guide available on the Instant Information DVD and
on the HP Technical Documentation Web site:
http://docs.hp.com
• If you do not use Ignite-UX or do not have a current
make_tape_recovery tape:
— 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.
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. Refer to the Software Distributor
Administration Guide for details.
