Installing HP-UX
Verifying and Completing the Installation
Removing Unwanted Software/Filesets
If it is necessary to remove software that has been installed on your
system, use the swremove utility. The swremove utility also
unconfigures the software as it removes it.
It is possible to remove your 10.20 ACE or Hardware Extension software,
although the system may have to manually rebooted, as follows:
• Use swremove to remove the appropriate ACE bundle.
• Exit swremove session after the bundle is removed.
• cd /
• /etc/shutdown -r -y 0
After the system has rebooted, the software will have been successfully
removed from the system.
Running freedisk
Another method of removing filesets from your system is to use the
HP-UX freedisk command. The freedisk command invokes an
interactive script that finds and optionally removes filesets that do not
appear to have been used since they were originally installed by
swinstall. This command is best run AFTER your new system has been
in operation for some time. See the manpage on freedisk for more
information. Note, you should be familiar with the swremove command
before you use freedisk.
Creating a Recovery System
You should immediately make a recovery version of your new system
after you have successfully installed it. This will help you recover your
system in case of problems. The Support Media User's Guide provides
instructions on how to use the COPYUTIL disk copy utility to make an
image of your system disk after installation. The manual is included in
the Support Media available through Subscription Services or orderable
from HP. You can also find information on restoring and backing up your
system in the manual HP-UX System Administration Tasks.
