Benefits
You can image multiple devices with the least amount of overhead. Devices to be imaged can have a
variety of operating systems installed on them, or even no operating system installed.
Using the multicast capabilities of your network, you minimize network traffic by sending the image
file across the network once for all devices to be imaged, rather than individually per device.
Limitations
Using the same image on multiple devices means they all have the same network identities.
However, you can install the ZENworks Linux Management Imaging Agent (
novell-zislnx ) on these
devices prior to performing the multicast, because this agent saves each device’s network identity
settings and restores them after the multicast image is applied.
ZENworks Script Bundle
Allows you to write a custom Linux bash script that is executed on PXE-enabled Linux devices.
This provides detailed control over ZENworks imaging operations, as well as most Linux-based
preboot tasks.
28.3.2 Preboot Services Menu
Where PXE is enabled on a device, the Preboot Services Menu can be displayed during the boot
process. The following menu choices are displayed on the Preboot Services Menu:
Š
Start ZENworks Imaging: Executes the effective Preboot Services imaging bundle.
Š
Start ZENworks Imaging maintenance: Displays the bash prompt, where you can execute
imaging commands.
Š
Disable ZENworks partition: Prevents an existing ZENworks partition from being used
during booting to execute the assigned Preboot bundles.
Š
Enable ZENworks partition: Allows an existing ZENworks partition to be used during
booting to execute the effective Preboot bundle.
Š Start DELL DTK: Starts the Dell OpenManage Deployment Toolkit (DTK) v2.1 in the
automated mode where assigned work is automatically performed.
Š
Start DELL DTK (Maintenance Mode): Starts the DTK in the maintenance mode, where
you can use the DTK bash prompt to manually configure the scripts and files used by the Dell
Configuration bundle.
Š
Exit: Resumes normal booting of the device.
You can use the ZENworks Control Center to configure whether this menu should be displayed on a
PXE-enabled device by selecting one of the following options:
Š Always Show Preboot Menu
Š
Never Show Preboot Menu
Š Show Preboot Menu if CTRL+ALT is Pressed
