Understanding Preboot Services in ZENworks Linux Management 339novdocx (en) 11 July 2008If you are not using Preboot Services, boot the device with the imaging boot CD or DVD andconsider installing the ZENworks partition to enable auto-imaging without needing to supply theCD or DVD. For more information, see Step 3 on page 355 of Section 29.7.2, “Enabling a Devicefor Imaging Operations,” on page 394. After you have installed the partition, reboot the device fromthe ZENworks partition.28.5.3 Reimaging Corrupted DevicesWithout data loss or undue disruption to users, you can fix devices that have become misconfiguredor corrupted.1. When a device needs to be fixed, have the user back up any files to the network that he or shewants 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 devicefrom the ZENworks partition or the Preboot Services imaging server (via PXE) to find andexecute the assigned bundle. If you are using PXE, make sure that Preboot Services is installedon your imaging server. For more information, see Chapter 30, “Using Preboot Services,” onpage 397.orIf the device does not have a ZENworks partition and is not PXE-enabled, the user should bootthe 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 StateYou can restore devices to a clean state, removing any changes or additions made since the last timeyou 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 Managementimaging server. For more information, see “Manually Taking an Image of a Device” onpage 405.2. If you are using Preboot Services, make sure that ZENworks Linux Management is installed onyour imaging server. For more information, see Section 29.1, “Preparing a Preboot ServicesServer,” on page 345.3. If you are using Preboot Services and the devices are PXE capable, make sure that PXE isenabled. For more information, see Section 29.6, “Enabling PXE on Devices,” on page 392.orIf you are not using Preboot Services or the Linux partition, create an imaging boot CD orDVD that points to the ZENworks Linux Management imaging server where the clean image isstored. For more information, see Section 29.2, “Setting Up the Preboot Services Methods,” onpage 346.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.
