Section 1.3, “System Administration,” on page 16
Section 1.4, “ZENworks Terms,” on page 17
1.1 Management Capabilities
The ZENworks Linux Management capabilities are divided as follows:
Section 1.1.1, “Software Package Management,” on page 13
Section 1.1.2, “Policy-Based Device Management,” on page 13
Section 1.1.3, “Automated Install and Imaging,” on page 14
Section 1.1.4, “Remote Management,” on page 14
Section 1.1.5, “Inventory Collection,” on page 14
Section 1.1.6, “ZENworks Linux Management Features Specific to Dell PowerEdge Servers,”
on page 14
1.1.1 Software Package Management
ZENworks Linux Management lets you install, remove, and roll back software on your Linux
devices. This is done through the use of bundles, which are collections of one or more software
(RPM) packages. ZENworks automatically resolves dependencies for any software packages it is
installing.
When you assign a bundle to a device, it is automatically installed on the device. If you want to give
the device’s user the choice of whether or not to install a software package, you can use catalogs. A
catalog is simply a group of bundles that appears in the ZENworks Linux Management Software
Updater client on the device; the user must initiate installation of any of the bundles in the catalog.
1.1.2 Policy-Based Device Management
ZENworks Linux Management provides a number of policies to help you manage the Novell Linux
Desktop, EvolutionTM e-mail client, Epiphany Web browser, and several other software applications.
Policies enable you to provide consistent operating system and application configuration settings for
your devices. You can lock the configuration settings so that users cannot change them.

14 Novell ZENworks 7.3 Linux Management Installation Guide
novdocx (en) 7 January 2010
1.1.3 Automated Install and Imaging
ZENworks Linux Management includes a service called Preboot Services that enables you to
perform tasks on devices before their operating systems boot up. Using Preboot Services, you can
automatically or manually do the following to a Linux device when it boots up:
Run scripted installations on the device, such as AutoYaST and kickstart.
Run ZENworks imaging scripts on the device.
Make an image of the device’s hard drives and other storage devices.
Restore an image to the device.
Apply an existing image to multiple devices.
Update the device’s BIOS.
To accomplish these tasks automatically, you simply need to have PXE (Preboot Execution
Environment) enabled on your devices, and have prebootable tasks configured and assigned to the
devices (configuration is done in the ZENworks Control Center, discussed later). Then, the devices
can automatically implement these tasks when they boot. Or, to manually implement the tasks, you
can configure devices to require user intervention during bootup.
1.1.4 Remote Management
ZENworks Linux Management provides the ability to use ZENworks Control Center (ZCC) to
remotely manage devices by using a graphical Web interface.
1.1.5 Inventory Collection
ZENworks Linux Management can gather extensive software and hardware inventory for all
managed devices, and it also enables you to create and export custom reports.
1.1.6 ZENworks Linux Management Features Specific to Dell
PowerEdge Servers
By combining ZENworks Linux Management capabilities with the Dell OpenManage toolkit
capabilities, you can manage your Dell PowerEdge servers from out of the box through the entire
server life cycle. ZENworks Linux Management provides the following features to help you deploy
and manage Dell PowerEdge servers in your ZENworks system:
Dell Configuration bundles: Let you configure the BIOS, BMC, RAID, and DRAC settings
on Dell PowerEdge servers and create a Dell utility partition. You can also select to run another
Preboot Services bundle after these configurations are complete. Dell Configuration bundles let
you configure a bare-metal PowerEdge server and quickly and easily put the server into
production.
Dell Update Package bundles: Let you update and configure hardware and system settings
(including BIOS, DRAC, RAID, BMC, and FRMW configurations) on Dell PowerEdge
servers. After you obtain Dell Update Packages from Dell by using the mirroring capabilities of
ZENworks Linux Management, you can easily assign the Dell Update Package bundles that are
automatically created to PowerEdge servers in your ZENworks system. It is easy for you to
determine if an updated Dell Update Package is available for PowerEdge servers in your
system and deliver the update.

About ZENworks Linux Management 15
novdocx (en) 7 January 2010
Advanced Dell inventory information: Lets you display inventory information specific to
Dell PowerEdge servers. This advanced inventory information helps you determine when
PowerEdge configuration settings need to be updated.
Advanced Dell reports: Let you run reports specific to Dell PowerEdge servers to find
devices that do not have valid Dell Update Packages installed or to show devices with Dell
applications installed (per device or per device model).
1.2 System Architecture
The ZENworks system architecture consists of two main components, ZENworks Servers and
managed devices. These components, organized into management domains, are referred to as
ZENworks Management Zones.
Figure 1-1 ZENworks Management Zone with a Primary Server, a Secondary Server, and Several Managed Devices
ZENworks Server
The ZENworks Server is the backbone of the ZENworks system. The first ZENworks Server
installed is called the ZENworks Primary Server. The Primary Server contains the following
ZENworks components:
ZENworks services: The ZENworks software that provides package management, policy
enforcement, inventory collection, imaging, and so forth. The main services are ZENworks
Server, ZENworks Loader, ZENworks Imaging Service, ZENworks Preboot Policy Daemon,
ZENworks Server Management, and ZENworks Management Daemon.
ZENworks Object Store: The Object Store is the information repository for devices, groups,
policies, bundles, and other ZENworks objects defined within the system. The Object Store,
which is version 8.8.3 of Novell eDirectoryTM, is set up and configured during installation. The
information in the Object Store is managed through the ZENworks Control Center.
Package repository: The package repository contains the RPM packages that are available for
delivery to managed devices within the system.
ZENworks Data Store: The Data Store contains information about the software packages
available for delivery, the hardware and software inventory lists collected from devices, and the
actions scheduled to take place within the system.

The Data Store can reside on the ZENworks Primary Server or it can reside on a remote server.
All ZENworks Servers require access to the Data Store. For accessibility and reliability
purposes, you might want to consider locating the Data Store on a server cluster.
The Data Store must be either a PostgreSQL or Oracle* database. You can install the
PostgreSQL database that is included with ZENworks Linux Management or you can use an
existing Oracle 9i database or PostgreSQL database.
Depending on the number and location of the devices you want to manage with ZENworks, you
might need additional ZENworks Servers, referred to as ZENworks Secondary Servers. Secondary
Servers contain the services, package repository, and Object Store, but not the Data Store. Basically,
Secondary Servers are mirrors of the Primary Server.
The ZENworks services and Object Store are added to a Secondary Server during installation and
configuration of the ZENworks software. Packages are automatically replicated from the ZENworks
Primary Server to all Secondary Servers based upon a schedule you can control (see “Replicating
Content in the ZENworks Management Zone” in the Novell ZENworks 7.3 Linux Management
Administration Guide). Like the Primary Server, a Secondary Server must have access to the Data
Store, whether the Data Store is located on the Primary Server or on another server.
Managed Device
A managed device is a server or workstation that you want to manage using ZENworks. The
ZENworks Agent must be installed on each device. The ZENworks Agent communicates with the
ZENworks Server to enable delivery of software packages, enforcement of configuration policies,
inventorying of hardware and software, and remote management of the device.
ZENworks Management Zone
A ZENworks Management Zone consists of one ZENworks Primary Server and one or more
managed devices. In addition, the Management Zone can include one or more ZENworks Secondary
Servers if required. The ZENworks Servers in the zone work together to manage the devices in the
zone.
If necessary, you can have more than one ZENworks Management Zone. There are two main
reasons for having multiple zones: 1) you have managed devices that are separated from your
ZENworks Servers by a slow WAN link, or 2) you need to have autonomous zones for
administrative purposes. These reasons are discussed in more detail in Section 6, “Installing a
ZENworks Secondary Server,” on page 47.
Information is not automatically shared between ZENworks Management Zones. However, you can
use the zlmmirror utility to copy software catalogs, bundles, or packages from one Zone’s Primary
Server to another zone’s Primary Server. The zlmmirror utility can also be used to pull catalogs,
bundles, and packages from the following servers: Dell FTP, YaST Online Updates, Red Hat
Network, Red Carpet®EnterpriseTM, ZENworks 6.x Linux Management, or Novell Updates. For
more information, see “Mirroring Software” in the Novell ZENworks 7.3 Linux Management
Administration Guide.
1.3 System Administration
The ZENworks system is administered at the Management Zone level through the ZENworks
Control Center, a task-based Web browser console.

About ZENworks Linux Management 17
novdocx (en) 7 January 2010
Figure 1-2 ZENworks Control Center
The ZENworks Control Center is installed on all ZENworks Servers in the Management Zone. You
can perform all management tasks on the Primary Server and most management tasks on the
Secondary Servers. The one management exception on Secondary Servers is the manipulation
(adding, deleting, modifying) of RPM or Dell Update Packages in a bundle. This task is not
supported because the Primary Server is the source server for packages, meaning that packages are
replicated from the Primary Server to Secondary Servers on a regularly scheduled basis.
Manipulating a package on a Secondary Server rather than on the Primary Server would result in the
modified package being replaced (or removed) the next time the Secondary Server’s packages were
updated from the Primary Server.
If you use Novell iManager to administer other Novell products in your network environment, you
can enable the ZENworks Control Center to be launched from iManager. For details, see
“ZENworks Control Center” in the Novell ZENworks 7.3 Linux Management Administration Guide.
In addition to the ZENworks Control Center, you can use a command line utility, zlman, to manage
the objects in your ZENworks system. For example, you can add packages to bundles, associate
policies with devices, register devices, and assign administrator rights. The main advantage to using
the command line utility is the ability to create scripts for handling repetitive or mass operations.
Like the ZENworks Control Center, the zlman utility is installed on all ZENworks Servers. It has the
same management restriction as the ZENworks Control Center, meaning that you should not use it
to manipulate packages on Secondary Servers. For more information about zlman, see “Command
Line Administration Utilities” in the Novell ZENworks 7.3 Linux Management Administration
Guide.
1.4 ZENworks Terms
