determines if the device belongs to the same zone as the server. If it does not, the server refers the
request to each server in its referral list until it finds the device’s home zone. The device is then
instructed to send all future requests to the correct daemon.
After you have specified all of the necessary servers in the referral list, you must place certain files
in the
\tftp
directories of each server in the list. Which files are copied and modified depends on
the version of ZENworks running on that server.
Note that the Preboot Referral Lists are only used by PXE devices, and only one ZENworks
Management Zone needs to have an active Proxy DHCP server and Preboot Referral List.
For the procedures in configuring referral lists, see Section 29.4.5, “Configuring the Server Referral
List,” on page 393 .
28.3.7 Intel Active Management Technology (AMT)
Review the following to understand how the Intel AMT functionality is used by ZENworks Linux
Management:
Š “Using AMT in ZENworks Linux Management” on page 337
Š
“Understanding AMT Provisioning” on page 338
Š “Accessing AMT Resources” on page 338
For more information on Intel AMT, see the Intel Web site (http://www.intel.com/technology/

Using AMT in ZENworks Linux Management
The Intel AMT functionality allows you to accurately identify devices, even if they have had
physical drive replacements. This provides ZENworks Preboot Services with persistent device
identification by providing ZENworks with nonvolatile memory for storing the unique device
identity.
With AMT and Preboot Services, if a device has a new, unformatted hard drive, ZENworks Linux
Management can instantly and accurately identify the device and apply the appropriate Preboot
bundle. If a device’s hard drive is inactive or its drive is replaced, ZENworks can automatically
identify the device in a preboot environment and provide the appropriate ZENworks Linux
Management-created image during a system rebuild.
AMT with ZENworks also provides easier hardware upgrading capability. For example, to upgrade
applications, some of your device hardware might not meet the minimum requirements. With AMT
and Preboot Services, as soon as the hard drives are replaced and before any agents or operating
systems are installed, you can continue to assign Preboot bundles using the device’s ZENworks
identity without having to re-register the device.
If you are using Intel AMT, support for it should be enabled in the
novell-
zmgprebootpolicy.conf
file.
