The
img session
command can take other parameters that allow you to designate the
master device and the imaging start time beforehand. See “ZENworks Imaging Engine
Commands” on page 617 for details.
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 425 .
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.
Using the ZENworks Imaging Engine Menu to Perform the Multicast Session
1
(Optional) Install the Novell ZENworks Linux Management Imaging Agent ( novell-zislnx ) on
each of the participating devices.
If you do not install the Imaging Agent on each participating device, the devices have duplicate
network identities. For more information, see
“Limitations of Multicasting Images” on
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
Section 29.2, “Setting Up the Preboot Services
Methods,” on page 346 .
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.
4 Enter
manual
at the bash prompt.
or
Select
Start ZENworks Imaging Maintenance from the Preboot Services Menu.
5 To identify each participating device in the multicast session, type
img
at the bash prompt to
display the ZENworks Imaging Engine screen.
6 Click Imaging , then click Multicast session (or on the task bar, click F7 Multicast ) to start the
Multicast Wizard.
7 Enter a session name.
