Users Guide

When the MSI engine is going through the installation sequence, it ignores all actions that are scheduled as rollback

actions. If a Custom Action, MSI Standard Action, or a installation action fails, then a rollback starts.

You cannot roll back an installation once it is completed; transacted installation is only intended as a safety net that

protects the system during an installation session. If you want to remove an installed application, you should uninstall

that application.

NOTE: Driver installation and removal is not executed as part of the installation transaction and therefore cannot

be rolled back if a fatal error occurs during execution.

NOTE: Installations, uninstallations, and upgrades that you cancel during installer cleanup, or after the installation

transaction is completed, are not rolled back.

Failed Updates

Apply the MSI patches and updates provided by vendors to the original vendor MSI packages provided. If you

intentionally or accidentally repackage an MSI package, or make changes to it directly, patches and updates may fail.

MSI packages must not be repackaged; doing so changes the feature structure and Globally Unique Identifier (GUID),

which break any provided patches or updates. To make any changes to a vendor-provided MSI package, use a .mst

transform file.

NOTE: A GUID is 128-bit long, and the algorithm used to generate a GUID guarantees unique GUID. The product

GUID uniquely identifies the application.

Upgrading Managed System Software

The Systems Management installer provides an Upgrade option for upgrading Server Administrator and other managed

system software.

The setup program runs the prerequisite checker, which uses the system's PCI bus to search for installed hardware,

such as controller cards.

The setup program installs or upgrades all of the managed system software features that are appropriate for the

particular system's hardware configuration.

NOTE: All user settings are preserved during upgrades.

The following procedures show how to upgrade Server Administrator and other managed system software.

Upgrading Guidelines

• You can upgrade to the latest version of Server Administrator from any of the previous three versions. For

example, upgrade to Server Administrator 7.3 is supported only for Server Administrator versions 7.0 and later.

• You can upgrade to the latest version of Server Administrator which includes Linux granular installation. If you

require the Linux granular installation options, you must uninstall the existing version of Server Administrator

and install the latest version of Server Administrator. For more information on Linux granular install options, see

Linux Installer Packages.

• To upgrade from versions earlier than 6.3, uninstall the existing version of Server Administrator and reinstall the

latest version of Server Administrator.

• When upgrading an operating system to a major version, uninstall the existing Systems Management software

and reinstall the latest Systems Management software. When upgrading only to an update level change (for

example, Red Hat Enterprise Linux 5 Update 7 to Red Hat Enterprise Linux 5 Update 8), upgrade to the latest

Systems Management software; all user settings are preserved.

NOTE: Uninstalling Systems Management software deletes its user settings. Reinstall Systems

Management software and apply the user settings.
