11.5 Imaging Devices

ZENworks Configuration Management includes a preboot service that enables you to perform tasks on devices before their operating systems boot up. Using Preboot Services, you can automatically or manually do the following to a device when it boots up:

  • Run ZENworks imaging scripts containing any commands that you can issue at the bash prompt

  • Take an image of the device’s hard drives and other storage devices

  • Restore an image to the device

  • Take part in a session where an existing image is applied to multiple devices

  • Take or restore a WIM image by using ImageX

  • Take or restore a Ghost image by using Symantec Ghost

To accomplish some of these tasks automatically, you simply need to have PXE (Preboot Execution Environment) enabled on your devices, then configure prebootable tasks in ZENworks Control Center and assign them to the devices. Then, the devices can automatically implement these tasks when they boot.

To manually implement the tasks, you can configure devices to require user intervention during bootup.

Using ZENworks Control Center, you can also replicate the tftp directory changes from a Primary Server to other Imaging servers (Primary Server or Satellite device with the Imaging role).

11.5.1 Setting Up Preboot Services

To use Preboot Services, you need to complete the tasks in the following sections:

Enabling PXE on a Device

Preboot Services requires PXE (Preboot Execution Environment) to be enabled on any managed device where you want to take or apply an image.

To check if PXE is enabled on a device, restart the device and select the boot option (F12 on most devices). PXE is enabled if there is a network boot option.

If PXE is not enabled on a device, edit the device BIOS to enable it. In order to ensure that the PXE environment is available each time the device starts, you can also change the boot order so that the NIC (Network Interface Card) option is listed before the other boot options.

Setting Up an Imaging Server

The Imaging Server is the PXE server that a device’s PXE engine connects to. To enable a ZENworks Server to function as an Imaging Server, you simply need to start the Novell Proxy DHCP Service on the ZENworks Server. When you start the service, you should also change the startup type from Manual to Automatic so that it starts whenever the server reboots.

Configuring the Third-Party Imaging Settings

If you want to use the third-party imaging solutions, you must configure the Third-Party Imaging Settings in ZENworks Control Center. ZENworks supports the following third-party imaging tools:

  • Microsoft ImageX that uses the WIM image file format and WINPE as the distro

  • Symantec Ghost that uses the Ghost image file format and WINPE as distro

The ZENworks third-party Imaging supports only PXE as the boot mechanism.

To configure the Third-Party Imaging settings:

  1. Ensure that Microsoft Windows Automated Installation Kit 1.0/1.1 (WAIK) is installed on the device running the ZENworks Control Center.

    You can freely download WAIK from the Microsoft Download Center website.

  2. (Conditional) If you want to run ZENworks Control Center on a 64-bit device, append the WAIK_installation_path\Windows AIK\Tools\x86 to the Path Windows system environment variable.

  3. Configure the third-party Imaging settings in ZENworks Control Center.

    1. In ZENworks Control Center, click Configuration tab.

    2. In the Management Zone Settings panel, click Device Management > Preboot Services > the Third-Party Imaging Settings panel.

    3. In the Upload WinPE Base Distribution (Requires Windows Automation Installation Kit) option, click Browse icon to upload the WIM Imaging file. In the Upload WIM Imaging Files dialog box, do the following

      1. Click Browse to browse for and select winpe.wim.

        By default, winpe.wim is installed in \waik\tools\petools\x86.

        NOTE:If you have not installed the Novell File Upload extension on this device, you must do so before you can browse to and upload directories to be installed.

      2. Click OK.

        This downloads the Imaging files from server to the device running ZENworks Control Center and also uploads files from the device to the server. The progress of download and upload of files is displayed in the Status field.

    4. In the Upload ImageX Files to Support WIM Imaging (ImageX.EXE) option, click Browse icon to browse for and select the Microsoft Imaging engine (imagex.exe) installed on the device running ZENworks Control Center. By default, imagex.exe is installed in \waik\tools\x86.

    5. In the Upload Ghost 11.5 or higher files to support Ghost imaging(Ghost32.exe) option, click Browse icon to browse for and select the Symantec Ghost engine (ghost32.exe) installed along with the Ghost solution on any device in your network.

    6. After configuring the third-party Imaging settings, click Apply.

    7. Click Status to view the status of content replication across all Primary Servers in the Management Zone. You must start the Imaging operation only when the status is Available.

      IMPORTANT:You must start the Imaging operation only when the status is Available.

  4. Enable PXE on the device.

  5. Ensure that you have a standard DHCP server, either on your Imaging Server or on another network server.

Configuring Third Party NTFS Driver Settings

You can download the latest high performance NTFS driver and save it on your system.You can view content replication status across all Primary and Satellite Servers with the Imaging role in the management zone. You can start the Imaging operation when the status is Available.
