Update Retriever to edit an existing package or create a new package in the
repository folder. Update Retriever uses an XML Descriptor file to define when an
update package is relevant and how to install the update package. For example,
you can create an XML Descriptor file that enables a specific update to be
downloaded and installed on a client system depending on the version of the
software already installed or existing hardware devices found on the system. After
using Update Retriever to customize update packages to fit the needs of your
enterprise, import the update packages into the network share repository folder
with Update Retriever.
On client systems, use System Update to search the network share repository
folder for update packages. System Update can then download and install relevant
packages from the network share repository folder to client systems. The following
illustration shows the relationship between the Lenovo Help Center, System
Update and Update Retriever when using Update Retriever to manage the update
process:
Non-Lenovo
By design, System Update and Update Retriever can be leveraged with
non-Lenovo systems. Non-Lenovo systems are not configured to utilize the Lenovo
Help Center Web site to download and install packages. If you are using a
non-Lenovo system with System Update, use Update Retriever to download
update packages to your network share repository or local system repository and
then use System Update to search for packages on your network.
