Reimaging Corrupted Devices; Restoring Lab Devices To A Clean State - Novell ZENWORKS LINUX MANAGEMENT 7.3 IR2 - ADMINISTRATION GUIDE 02-12-2010 Administration Manual

28.5.3 Reimaging Corrupted Devices

Without data loss or undue disruption to users, you can fix devices that have become misconfigured
or corrupted.
1. When a device needs to be fixed, have the user back up any files to the network that he or she
wants to keep (if possible).
2. Create and/or assign an appropriate imaging bundle to the device.
3. If it is a device with a ZENworks partition or it is PXE-enabled, the user should boot the device
from the ZENworks partition or the Preboot Services imaging server (via PXE) to find and
execute the assigned bundle. If you are using PXE, make sure that Preboot Services is installed
on your imaging server. For more information, see
page 407.
or
If the device does not have a ZENworks partition and is not PXE-enabled, the user should boot
the device with the imaging boot CD or DVD and restore the appropriate images manually.
4. After the image is laid down, restore any user files that were backed up to the network.

28.5.4 Restoring Lab Devices to a Clean State

You can restore devices to a clean state, removing any changes or additions made since the last time
you restored the image on that device. This is useful for updating lab devices.
The following steps assume that the devices are unregistered.
1. Create an image of a clean model device and store it on a ZENworks Linux Management
imaging server. For more information, see
page 415.
2. If you are using Preboot Services, make sure that ZENworks Linux Management is installed on
your imaging server. For more information, see
Server," on page 353.
3. If you are using Preboot Services and the devices are PXE capable, make sure that PXE is
enabled. For more information, see
or
If you are not using Preboot Services or the Linux partition, create an imaging boot CD or
DVD that points to the ZENworks Linux Management imaging server where the clean image is
stored. For more information, see
page 354.
Deploy each lab device as follows:
1. Physically connect the device to the lab network.
2. If you are using Preboot Services, boot the device from the Preboot Services imaging server.
or
If you are not using Preboot Services, boot the device with the imaging boot CD or DVD and
install the ZENworks partition. For more information, see
Section 29.7.2, "Enabling a Device for Imaging Operations," on page
