Un-installing HP-UX 11i v1
If you cannot resolve problems after installing or updating to HP-UX 11i
v1, you may wish to un-install 11i. The process depends upon the install
or update process you followed:
Assuming that you have made a make_tape_recovery or
make_net_recovery tape using Ignite-UX, boot the system from that
media to return the OS and any archived applications to the previous
release. This is covered in the Ignite-UX Administration Guide,
available on the HP-UX 11i v1 Instant Information CD and on this
web page:
http://docs.hp.com/
If you don’t use Ignite-UX or do not have a current
make_tape_recovery tape, read on....
If your applications and data are on a separate disk from the OS,
cold-install the previous OS over 11i. This ensures a clean OS
installation, removing all previous upgrade and patch information.
If applications and/or data 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 what 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. See the Software Distributor Admin-
istration Guide for details.
