installupdate - Invokes the Update Installation procedure
/sbin/installupdate [-nogui] [-u] {ris_server:}
/sbin/installupdate [-nogui] [-u] {[cdrom_device]
[cdrom_mount_point]}
On systems with graphics capability, this option invokes
the text-based, menu driven user interface rather than the
graphical user interface. Invokes an unattended Update
Installation. Unattended means that barring any problems
during the Update Installation (such as file type conflicts,
insufficient disk space, and blocking layered
products), there is no user interaction required. This
option builds a kernel with all kernel components and does
not provide the opportunity to archive obsolete files
before the Update Installation process deletes them.
If the analysis phase of the update discovers file
type conflicts, insufficient disk space, or blocking
layered products, the update process stops and
prompts you to correct the problem or problems
before the update resumes.
An Update Installation updates the base operating system
software and the worldwide language support (WLS) software
to the next released version of the operating system on a
single 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.
Cluster software is updated by a process called a rolling
upgrade. An Update Installation is one of several stages
in a cluster rolling upgrade. The cluster rolling upgrade
process is documented in the TruCluster Server Cluster
Installation manual and in clu_upgrade(8).
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 during 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 singleuser
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 command line.
The functions performed during the Update Installation
process include: Detecting and deleting obsolete system
files, files that were previously 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 version of the operating system. Certain
file type conflicts prevent the Update Installation from
continuing, and you must resolve these conflicts 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. Checking for installed layered
products that may not be compatible with the new version
of the operating system. The product or products may need
to be reinstalled later. 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 analysis
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.
The following examples assume you have performed all
required preinstallation tasks, have shut down the system
to single user mode, and have mounted the local file systems
with the <filename> /sbin/bcheckrc</filename> command.
See the Installation Guide for more information
about these steps.
To start an unattended Update Installation from a CD-ROM
device: # /sbin/installupdate -u /dev/disk/cdrom0c
To start the Update Installation using the text-based
interface from a CD-ROM device that is mounted on the /mnt
mount point: # /sbin/installupdate -nogui /mnt
To start the Update Installation from a RIS server named
server1: # /sbin/installupdate server1:
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.
