Lenovo System Update Solution (Deployment Guide) - Manual (Page 46)

Working with update packages
An update package is made by bundling several files together. Updates packages
consist of a self-extracting installer program, an XML Descriptor file that defines
the update, and one or more NLS translated readme files. An update may also
optionally include one or more NLS translated license files and one or more
external detection files. Applicable update packages must match the triplet on the
client system. Triplets are the combination of the machine type, operating system,
and language.
Note: If you have multiple machine type/model numbers selected on the Update
Retriever main window, all packages common to the multiple systems that you
select on the Applicable Updates window will result in a check mark next to each
system. Clearing the check box for one system will clear the check boxes for all of
the systems.
Downloading and installing updates
The following list provides the three different methods you can use to download
and install update packages:
v Lenovo Help Center Web site
v Locally on a client system
v Network shared drive
The following sections define each method in detail, so that you can provide the
best configuration for your organization.
Using the Lenovo Help Center Web site
You can manually initiate a check for new updates using System Update. System
Update notifies you that the following information is communicated to determine
the applicable update packages for your system:
v Machine type
v Operating system
v Language
System Update will then provide a selectable list of updates. You will have the
option to defer updates, so you can download the update package but install it at
a later time, or you can download and install the update packages immediately.
Once you select the updates to download and confirm the selections, the updates
are downloaded and installed your system.
Using a repository on a client system
You can set up your computer to store update packages locally. Do this by creating
a folder on your computer to be used as the repository, and then change the
repository path in the registry that points to that repository on your local
computer.
Using a repository on a network share
You can download and install new updates from a repository that resides on a
network share. System Update will retrieve the end user credentials (user name
and password) needed for authentication from the application properties as
encrypted strings. If a user name and password does not exist, System Update will
still attempt to connect to the network share but will prompt the user to provide a
user name and password.
