installupdate(8) System Manager's Manual installupdate(8)
NAME
installupdate - Invokes the Update Installation procedure
SYNOPSIS
/sbin/installupdate [-nogui] [-u] {ris_server:}
/sbin/installupdate [-nogui] [-u] {[cdrom_device], [cdrom_mount_point]}
OPTIONS
On systems with graphics capability, this option invokes the text-based, menu driven user interface rather than the graphical user inter-
face. Invokes an unattended Update Installation. Unattended means that barring any problems during the Update Installation, there is no
user interaction required. This option builds a kernel with all kernel components, automatically removes blocking software, and does not
provide the option to archive obsolete files before the Update Installation process deletes them.
DESCRIPTION
The installupdate command invokes the Update Installation. An Update Installation updates the base operating system software to the next
released version of the operating system. The Update Installation preserves user files, data files, print and network configurations, user
accounts, and any other system setup and customization you may have done.
An Update Installation does not update layered products, but you can still perform an Update Installation if your system is installed with
layered products. Some layered products operate properly with the new version of the operating system and others must be reinstalled with
a version that is compatible with the new version of the operating system. You are notified accordingly. You can delete these products dur-
ing the Update Installation process and then reinstall them on the updated system.
There are two distribution methods for an Update Installation: From the operating system CD-ROM (from a mount point or CD-ROM device) Over
a network connection to a Remote Installation Services (RIS) server that is serving the most recent version of the operating system
The Update Installation is performed from single-user mode. You must be superuser or the user root to bring a system down to single-user
mode. Do not boot to single-user mode to perform an Update Installation.
Whether you are using CD-ROM or RIS, the Update Installation process is started by entering the /sbin/installupdate command from the com-
mand line.
The functions performed during the Update Installation process include: Detecting and deleting obsolete system files, files that were pre-
viously shipped with the older version of the operating system but are not in the new release. You have the option to archive these files
to a file name of your choice before they are removed from the system. Checking for file types that you have changed since the last ver-
sion of the operating system. Certain file type conflicts prevent the Update Installation from continuing, and you must resolve these con-
flicts before you can restart the Update. This feature preserves the integrity of the new operating system about to be installed. Checking
for adequate free disk space to ensure the Update Installation has enough room for temporary processing and there is enough disk space for
the new software subsets that were introduced in the new version of the operating system. Saving unprotected customized files to files
with extensions to preserve customizations that were made to unprotected system files. These files are not expected to be modified and are
not merge protected from the Update Installation, therefore they are saved with the extension. Performing merges of protected system
files. These are files that are shipped as part of the operating system that are expected to be customized (for example, the /etc/hosts
file). These files are merge protected, which means that user customizations are preserved and newly introduced functionality is merged
into the already customized file. Using the setld command to load new software subsets. Subsets previously installed are updated as well
as any new mandatory subsets that were introduced in the new version of the operating system. Base operating system subsets and Worldwide
Language Support (WLS) subsets are updated. Building a custom kernel and rebooting the system with that kernel. Executing user-supplied
update_preinstall and update_postload files, if they exist, to perform customizations on the updated system.
An Update Installation completes in 45 to 120 minutes. Actual time varies depending on your processor type, the number of software subsets
that have to be updated, network traffic, and the speed of the CD-ROM device. You need to respond to prompts only during the initial analy-
sis phase of the Update Installation
Postinstallation tasks may include manually merging file customizations into those files that were not done automatically and rebuilding
the kernel with layered product kernel components. It is recommended that you review the Update Installation log files located in the
/var/adm/smlogs directory when the Update Installation is complete.
FILES
Contains a log of the output that was displayed to the screen during the Update Installation. Contains a list of the files that were saved
to a extension. Contains a list of the files that were saved to a extension. Contains a list of the protected system files that failed to
automatically merge during the Update Installation.
