At the command prompt of the managed device that has the ZDM 7.x agent and the ZENworks Agent with Asset Management installed, run the following command:
zac fsg –d
This takes a backup of DeviceGUID and DeviceID files, and subsequently deletes the files. The .sav file is created in zenworks_installation_directory/novell/zenworks.
Launch ConsoleOne on the ZDM 7.x server, and create a task to take an image of the managed device.
Reboot the managed device in the PXE mode.
An image of the device is taken and it is saved in the location that you specified while creating the task to take an image in Step 2.
