Installing, Uninstalling, and Upgrading Dell OpenManage ITAssistant 79
Upgrading IT Assistant After Migrating to Windows Server 2003
If a system with IT Assistant installed is migrated to Windows Server 2003
and then upgraded to a recent version of IT Assistant, systems configured
with the CIM protocol may no longer be discovered. This may occur due to
encryption differences between Windows Server 2003 and earlier versions of
Windows. To solve this, reset the password for the CIM user. In the IT
Assistant user interface, go to Discovery and Monitoring, select Ranges and
right-click Include Ranges. Click New Include Range to run the New
Discovery Wizard, where you can specify the new CIM user name in the CIM
Configuration window.
System Recovery on Failed Installation
If IT Assistant installation encounters a fatal error during setup, your system
may become unstable. To address this problem, Dell IT Assistant installer
provide the ability to roll back or return the system to its fully-working
condition prior to the failed installation.
The Windows Installer service provides Dell IT Assistant installer the ability
to roll back by maintaining an undo operation for every operation that it
performs during an installation, uninstallation, or any other configuration
change. If some aspect of the installation fails during an installation session,
the Windows Installer service can precisely return the system to its previous
stable state. This feature includes restoration of deleted or overwritten files,
registry keys, and other resources. Files that are deleted or overwritten during
the course of an installation or removal are temporarily saved to a backup
location, so they can be restored if necessary. After an installation finishes
successfully, all temporary backup files are deleted.
An installation cannot be rolled back once it has successfully completed. A
transacted installation is intended as a safety net that protects the system
during a given installation session. If you want to remove an installed
application, for example, you should uninstall that application.
When upgrading a previous version of Dell IT Assistant to the current
version, an error during upgrade will rollback the system to its previous state.
NOTE: Installations, uninstallations, and upgrades canceled by the administrator
during installer cleanup or after the installation transaction is completed will not be
rolled back.
