Information captured from the ZENworks ISD service is deleted after ZENworks is upgraded to 11.2.3a

Source: ZENworks 11; Preboot Services and Imaging.
Explanation: In ZENworks 11.2.3a and higher versions, the Imaging agents support devices with GPT disks that reserve sectors from 0 to 33. The agents use sectors 34 to 61 to write any ISD information and so these sectors need to be kept free.
Action: To clear any data from sectors 34 to 61 run the following command:

#dd if=dev/zero of=/dev/sda bs=512 seek=34 count=28

NOTE:Do not clear any sectors below 34 as this would remove the boot loader code of the operating system.

File name not displayed when an Imaging operation fails

Source: ZENworks 11; Preboot Services and Imaging.
Explanation: Changes have been made in the Imaging Engine interface to reduce the number of screen refreshes that occur during Imaging operations with the Tuxera driver. One such change is not to show the full filenames during Take Image and Restore Image operations. As a result, for some particular failures, the filename of the current file being backed up or restored may not be displayed on the GUI.
Action: You need to verify the imglog file to detect where the failure occurs during the Take Image or Restore Image operations. Do the following:

  1. Enable the developer logs by running the export DEVELOPER_LOG=a command in the Imaging distro mode.

    The logs are stored in the /imglog file.

  2. Search for the following strings to find the file on which the failure occurs as follows:

    For Take Image operation: The last occurrence of the lnxfsTuxeraBaseImageToArchive string. This line and the next line contains the path to the file that has failed.

    For Restore Image operation: The last occurrence of the ntfsTuxeraWriteFileFromArchive string. This line contains the path to the file that has failed.

Product.Version for WADK32: 6,2,0,0

Unable to upload 32-bit and 64-bit ImageX files at the same instance

Source: ZENworks 11; Preboot Services and Imaging.
Explanation: In the Third-Party Imaging Settings panel in ZENworks Control Center, you cannot upload 32-bit and 64-bit ImageX files in the same instance. Since the binary files for both the ImageX files have the same name (imagex.exe), the last uploaded file gets overwritten by the new file.
Action: The 32-bit and 64-bit ImageX binary files have to be uploaded with separate upload instances.

On restarting the server, the pbserv or the novell-zmgprebootpolicy Imaging services are dead

Source: ZENworks 11; Preboot Services and Imaging.
Explanation: During the device startup, the Server IP address is being viewed as a non-local IP and is causing the services to be in the unused state. This occurs when Network Manager is enabled on Linux Servers.
Action: Do the following for the services to run correctly:

  1. Add the following line in the /etc/sysct1.conf file:

    # allow processes to bind to the non-local address net.ipv4.ip_nonlocal_bind =1

  2. Reload the /etc/sysct1.conf file by running the $ sysct1 -p /etc/sysct1.conf command.

ZENworks WADK Imaging works only on hardwares that are supported on Windows 8

Source: ZENworks 11; Preboot Services and Imaging.
Explanation: WADK has WINPE 4.0 which is based on Windows 8 kernel. So, you need to validate if your system hardware meets the ZENworks WADK Imaging requirements to perform Imaging operations.
Action: To be able to perform Imaging operations, validate your system as follows:

  1. Download the coreinfo.exe file from Windows Sysinternal (Download and Usage Information).

  2. Run the tool to determine if the system has support for NX, PAE, and SSE2.

  3. If your system is reported to support NX, PAE, and SSE2, you can use WADK to image the device. Else, use the compatible WIM mode based on WINPE 3.x.

IMPORTANT:In some 64-bit processors like Intel Xeon, there are two boot modes - Enabled and Capable. In both modes SMBIOS indicates that the processor is a 64-bit processor. However, if the mode is set to Capable, the system works as a 32-bit processor, and the 64-bit WADK does not boot. To use ZENworks Imaging on these 64-bit processors, the 64-bit mode should be set to Enabled in BIOS for 64-bit WADK to boot correctly. For more information, see System Management BIOS (SMBIOS) Reference.

NOTE:For VMware Virtual machines, only 32-bit WAIK or 32-bit WADK boot is applicable.

For more information, see TID 7013318.
