2.2 Preparing a Satellite with the Imaging Role

A Satellite is a managed device that can perform certain roles that a ZENworks Primary Server
normally performs. A Satellite can be any managed device (server or workstation). When you
configure a Satellite, you specify which roles it performs (Imaging, Collection, or Content). A
Satellite can also perform roles that might be added by third-party products that are snap-ins to the
ZENworks 10 Configuration Management framework.
The following sections provide detailed information:
Section 2.2.1, "Understanding the Imaging Role," on page 42
Section 2.2.2, "Configuring the Imaging Role to the Satellite," on page 42
Section 2.2.3, "Illustrating the Preboot Services Processes on the Imaging Satellite," on
page 43

2.2.1 Understanding the Imaging Role

The Imaging role installs the Imaging services and adds the Imaging role to the device. The Satellite
with the Imaging role is called Imaging Satellite. The Imaging Satellite requires both Proxy DHCP
and DNS server to be running in the Imaging environment.
The Imaging roles allows you to:
Perform all the Imaging operations on the device by using it as an Imaging server. The
operations includes taking an image and applying an image within as well as across subnets by
using unicast or multicast imaging.
Achieve load balance for the Primary Server.
Replicate add-on images to the Satellite.
The Satellite communicates with the Primary Server for the Imaging operations in the Auto mode
through ZENworks Control Center.
On the managed device, the Imaging module is inactive until you promote the managed device to be
a Satellite with the Imaging role or the Imaging role is added to an existing Satellite. This activates
the Imaging services on the device, and enables you to perform the Imaging operations in auto and
maintenance mode.
The Imaging components installed on the device include Novell ZENworks PXE Client Files,
Novell ZENworks PXE Update Files, and Novell ZENworks Multicast Application (zmgmcast).The
Imaging services installed on the device include Novell TFTP, ZENworks Preboot Policy
(zmgpbpolicy), ZENworks Preboot (pbserv), and Novell Proxy DHCP. All services, except for
proxy DHCP, are automatically started. You can manually start or stop the proxy DHCP service
from ZENworks Control Center.

2.2.2 Configuring the Imaging Role to the Satellite

You can configure the Imaging role to the Satellite by using ZENworks Control Center or the zman
command line utility.
