Preparing predefined computer to boot with LinuxPE
If you have provisioned computers before they are added to a network, then Deployment Solution identifies such computers as predefined computers. You can configure the predefined computers to boot in the preboot environment before you install the Linux operating system (OS). The computers boot in the preboot environment with a PXE image.
The PXE image for Linux OS is known as LinuxPE image. For Linux, a PXE image is created using the preboot configuration files, LinuxPE that Deployment Solution supports, the ULM Agent, and the Deployment plug-in for Linux. The Deployment Plug-in is required for the execution of deployment tasks on the client computer.
If you add a predefined computer through the Settings > Deployment > Predefined Computer dialog box of the console, then Deployment Solution boots all unknown computers as potential predefined computer based on a criteria. The criteria is that you have not specified any value for the hardware identifier fields such as MAC address, Serial Number, and UUID, in the dialog box.
The following process addresses how you must configure the settings to boot a predefined Linux computer in the preboot environment. After the computer boots in the preboot environment, the communication with the Notification Server is established and the computer is registered as a managed computer.
You must perform the following steps to boot a predefined computer with the LinuxPE image:
Table: Booting a predefined computer with LinuxPE image
Launch the console
Launch the Symantec Management Console.
You can launch the console either from the Start menu of the Notification Server computer or from any computer of the network. To access the console from a different computer, you must type the following:
http://<IP address of NS>/altiris/console
Install the Network Boot Service on a site server
You must install the Network Boot Service (NBS) on a site server and also enable the policy before you configure the client computer to boot in the preboot environment.
For the predefined computer, you configure the NBS General Settings that lets you select the LinuxPE image to boot the client computer with and also configure the boot menu. Besides, you can also configure the NBS Global Setting that lets you filter computers based on MAC address to which the NBS site server must or must not respond.
(optional) Set up the Re-Deployment (Managed Computer) menu in the Initial Deployment Settings dialog box
In the Initial Deployment Settings dialog box, you can configure the Re-Deployment (Managed Computer) menu to execute jobs or tasks on the predefined computer after the computer boot in the preboot environment.
Add the predefined computer to the network and wait for the computer to boot in the preboot environment
After a predefined computer is added to the network, the computer boots with the LinuxPE image that you configured.
If you have not specified any values for the hardware identifier fields, then after the computer boots to the preboot environment, you have an option to execute the Initial deployment tasks that you configured for the unknown computer. The hardware identifier fields are, MAC address, Serial number, and UUID that you specify in the Add Predefined Computer dialog box.
