The img session command can take other parameters that allow you to designate the
master device and the imaging start time beforehand. See
Commands" on page 617
6 (Conditional) If you have not already done so, start the multicast session from the master
device or from the imaging server.
Master device: To start the multicast session from the master device, after all of the other
devices have registered as participants, click Start session.
If you start the session from the master device, the session master must be a device. If you start
the session from the imaging server, the session master must be an imaging server using a
previously saved image file.
The ZENworks Imaging Engine begins creating the image of the master device and the image
is sent to and put down on each participating device. Any problems are reported and displayed
on the master device.
Imaging server: To start the multicast session from the imaging server, follow the steps under
"Initiating a Multicast Session from the ZENworks Imaging Server" on page
7 At each participating device, when the imaging is done, do the following to boot the device
with the new operating system:
7a At the Linux prompt, type lilo.s, then press Enter.
7b Press Ctrl+Alt+Delete.
If the device doesn't boot to the new operating system (that is, if the Linux prompt is
displayed), enter lilo.s again and reboot the device a second time.

network identities. For more information, see
page 342.
2 Create an imaging boot CD or DVD for each person who will assist with the multicast session,
or enable PXE on the participating devices.
If you don't know how to do this, see
Methods," on page
3 At each device, including the master device (unless you are starting the multicast session from
the imaging server), access a Linux prompt by using the imaging boot CD or DVD, or if it is
PXE-enabled, boot it.
