[. . . ] Physically connect the device to the lab network. If you are using Preboot Services, boot the device from the Preboot Services imaging server. Understanding Preboot Services in ZENworks Linux Management 339 novdocx (en) 11 July 2008 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 Step 3 on page 355 of Section 29. 7. 2, "Enabling a Device for Imaging Operations, " on page 394. After you have installed the partition, reboot the device from the ZENworks partition. At the end of each lab session, assign the Preboot bundle to the lab devices. Reboot each device and let it be auto-imaged by its assignment to a ZENworks Preboot bundle. 28. 5. 5 Setting Up Devices for Future Reimaging With minimal disruption to users, you can enable existing devices for possible future reimaging. This process might need to be phased in by local administrators. Each administrator can do the following: 1. Install the Novell ZENworks Linux Management Imaging Agent (novell-zislnx) on each device. If the devices are PXE capable, make sure PXE is enabled (see Section 29. 6, "Enabling PXE on Devices, " on page 392) and make sure that ZENworks Linux Management is installed on your imaging server (see Section 29. 1, "Preparing a Preboot Services Server, " on page 345). or Prepare a few sets of imaging CDs or DVDs that users can use when they run into trouble (see Section 29. 2, "Setting Up the Preboot Services Methods, " on page 346). These devices should point to an imaging server that contains the same clean images used for new devices. If a user runs into trouble, use the strategy for reimaging corrupted devices. For more information, see Section 28. 5. 3, "Reimaging Corrupted Devices, " on page 339. 28. 5. 6 Multicasting Device Images The following sections explain the multicasting images feature: "Understanding Multicasting" on page 340 "Practical Uses For Multicasting" on page 341 "Automatic Multicasting Example" on page 342 For instructions on using multicasting, see Section 30. 2, "Multicasting Images, " on page 419. Understanding Multicasting Multicasting is a way to send the same image to multiple devices without sending that image multiple times across the network. It is done by inviting participants to join a multicast session. Multicasting is similar to broadcasting on the network, because you send the image once to the network and only those devices belonging to the multicast session can see and receive it. For example, if you have 10 devices in the multicast session and the image is 3 GB in size, your network experiences only 3 GB of network traffic to image all 10 devices. Without multicasting, the network experiences 30 GB of network traffic to image all 10 devices individually. 340 Novell ZENworks 7. 2 Linux Management Administration Guide novdocx (en) 11 July 2008 The devices to be imaged must be physically connected to the network. They can be devices with existing operating systems of any kind, or they can be new devices with no operating system installed. IMPORTANT: For multicasting to work properly, all routers and switches on the network must have their multicast features configured. Otherwise, multicast packets might not be routed properly.
