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
-nogui
On systems with graphics capability, this option invokes the text-
based, menu driven user interface rather than the graphical user
interface.
-u 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.
DESCRIPTION
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 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 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 .PreUPD 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 .PreUPD 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.
EXAMPLES
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:
FILES
