IMPORTANT: The image is sent to and put down on each participating device only after you
initiate the multicast session from each participating client.
3 To view the status of the multicast session, enter:
Argument Description
session_name (Required) The session name is any string that uniquely identifies this multicast
session from other multicast sessions that might be in progress on the network.
-p path (Required) The path to the image to be multicast, which is located on the
imaging server. This must be the full path.
-i IP_address (Optional) The IP address of the imaging server.
-f file_set_number (Optional) File sets are assigned to the current ZENworks Image bundle using
this information. File sets are defined on the imaging server from the base
image using the
Image Explorer utility, which can be run on a Windows device
from a Linux server running Samba. The Image Explorer utility is located at /
opt/novel/zenworks/zdm/winutils/ImgExp.exe
on the Linux server.
When you define a file set using Image Explorer, you specify files and
directories to be excluded from the image. Thus, a file set is a subset of the
original image that excludes the files you select in Image Explorer. A separate
image file is not created for the file set; instead, a file set contains internal
attributes representing the excluded information. Therefore, even though a file
set does not exist as a separate, physical image file, it is accessed as though it
is, placing the image on the receiving device, minus the excluded files.
For example,
device1image.zmg
is the image file on your imaging server.
You use Image Explorer to determine which data to exclude and assign this to
a file set number, such as 2. When a device assigned to this ZENworks Image
bundle boots, it is imaged with the smaller version (file set 2) of
device1image.zmg
.
File sets provide an advantage because you can create a base image and
modify it slightly for various devices, instead of creating separate, somewhat
different base images for each device. However, because file sets only concern
excluded files, if you add files to the base image using Image Explorer, all file
sets include those additional files. If you don’t want them included in a file set,
you must use Image Explorer to exclude these new files from that file set.
There are a maximum of 10 file sets. Each of the ten file set numbers
represents the original base image, until you use Image Explorer and assign
the results to a file set number.
IMPORTANT: If you create 10 different file sets, then the original image can be
lost. If you want to maintain the original image’s information, do not use Image
Explorer to assign exclusions to file set 1, which is the default file set if you
don’t select a file set when using this wizard.
-t time_wait (Optional) If not enough devices have booted to fulfill the Client Count
requirement, the multicast session begins if a participating device boots and a
certain amount of time passes without another participating device booting.
Specify this amount of time. The default is 5 minutes.
-c client_count (Optional) The number of participating devices you want to have booted before
the multicast session begins. If you do not specify a number, the default is 1.
