B.5 Configuring Workstation Imaging

This section contains the following information:

B.5.1 Configuring Workstation Imaging for a Novell Cluster Services Environment

The following steps provide the configuration information you need to configure Workstation Imaging to work in the clustering environment after installation.

  1. Modify the Virtual Server object in the unload script.

    1. In ConsoleOne, open the Cluster object, right-click the NWCS volume resource, then click Properties.

    2. On the Unload page, type unload imgserv <<y in the Script text box, then click Apply.

    3. On the Cluster State page, select the resource volume you want to offline, click Offline, reselect the same resource volume, then click Online.

      This step restarts the imaging server from scratch.

  2. Edit the zfdstop.ncf file in shared_cluster_volume:\system, then comment the following line: 

    Unload imgserv

B.5.2 Multicast Issue in a Novell Cluster Services Environment

Imaging multicast sessions that you set manually at the Image Server console (imgserv.nlm) are lost when the virtual server hosting imgserv.nlm fails over. The only workaround is to re-create those multicast sessions and restart the process manually.

B.5.3 Configuring Workstation Imaging Preboot Services for a Novell Cluster Services Environment

Previously, ZENworks Desktop Management did not fully support the Workstation Imaging component in Novell Cluster Services (NCS) environment, particularly if used in conjunction with ZENworks Preboot Services (PXE). With the release of ZENworks 7 Desktop Management, however, using Preboot Services for Workstation Imaging is now supported in a Novell Cluster Services 1.7.2 (or later) environment

Use the following steps to install and use ZENworks 7 Workstation Imaging with PXE in a Novell Cluster Service 1.7.2 (or later) environment:

  1. Make sure that you have met all of the prerequisites for installing ZENworks 7. For more information, see Section II, Preparation.

  2. Install ZENworks 7 Desktop Management in the Novell Cluster Services environment. In an upgrade situation (ZENworks 6.5 upgrading to ZENworks 7), the ZENworks 7 Desktop Management installation program allows the selection and installation of new components that were not previously installed.

  3. Install ZENworks 7 Desktop Management in the same servers where you installed the original version of ZENworks 7 Desktop Management.

  4. In the virtual server system directory, locate the dts.ini file. For example: cvol:system/dts.ini.

  5. Open dts.ini in a file editor, then change the IP setting in the following line: 

    TransactionServerClusterIP=IP_Address

    The IP address must point to the IP Address of the virtual server in the cluster. If this line is not present in the file, you need to add it.

  6. Save the edited dts.ini file.

  7. Locate the tftp.ini file located in the same system directory.

  8. Open tftp.ini in a file editor, then change the IP setting in the following line:

    IPADDRESS=IP_Address

    The IP address must point to the IP Address of the virtual server in the cluster.

  9. Save the edited tftp.ini file.

  10. Locate the pdhcp.ini file located in the same system directory.

  11. Open the pdhcp.ini file in a file editor, then change the IP setting in the following lines:

    TRANSACTION_SERVER_IP=IP_Address
PDHCP_Server_IP=IP_Address

    The IP address in both lines must point to the IP Address of the virtual server in the cluster.

    In Novell Cluster Services 1.7.2, the following line is also included in the pdhcp.ini file:

    TFTP_SERVER_IP=IP_Address

    This IP variable must also point to the IP Address of the virtual server in the cluster.

  12. Save the edited pdhcp.ini file.

  13. Copy dts.ini, tftp.ini, and pdhcp.ini to /sys:system in each of the nodes (that is, servers) in the cluster.

  14. Take the resource offline, then bring it back online to reload ZENworks services.
