Data Mover provides the dsa_configfabric script as part of the installation package to make the fabric configuration process faster and easier. The script generates two XML files that contain the source and target system fabric definitions. The script uses DSC commands to extract information about the source and target media servers and nodes. It then generates the following two fabric files:
  • One file defines the connection from source nodes to target media servers and source nodes to source media servers
  • The other file defines the connection from the target nodes to source media servers and target nodes to target media servers
  1. Before running the configuration script, make sure that all interfaces that will be part of the fabric are available in the DSC media server configuration.
  2. [Optional] Use one of the following two methods if interfaces are missing from the DSC configuration:
    Method Description
    Manually export, add interfaces, and reconfigure each media server
    1. Export the media server configuration:

      dsc export_config -t MEDIA_SERVER -n media_server_name -f media_server_XML_config_filename

    2. Edit the media_server_XML_config_filename and add the missing interfaces.
    3. Save the changes:

      dsc config_media_servers -f media_server_XML_config_filename

    Reset all the media server settings registered with DSC Run the following command:

    dsc config_media_servers -f media_server_XML_config_filename

    Using the hardware upgrade script resets the settings for all the DSCs using that media server. Use with caution.
    The media server configuration should look similar to the example below after the hardware resets.
    Media Server Name   Port    Pool Shared Pipes   IP Address(es)   NetMask(s)     
    server1_ms         15401   100                 10.0.***.***  
    server2_ms         15401   100                 10.1.***.***  
  3. Use the following DSC commands to confirm the media servers and system nodes are recognized by DSC:
    • dsc list_components -t system
    • dsc list_components -t media_server
    • dsc list_components -t target_group
  4. Run the script to generate the fabric for the source and target systems.
    Use the following help command output for the list of available script parameters:
    HELP: dsa_configfabric -s [source_system] -t [target_system]
    -s | --source [source_system]		Source system name
    -t | --target [target_system]		Target system name
    -f | --file   [accept_list_file_path]   The file contains one or combination of the following two entries:
    					1. Interface IP address, Node name, and Media Server name defined by DSC separated by tabs
    					2. Interface IP address defined in DSC
    					If the line entry is applicable to the questionnaire, an interface for the connection is selected automatically based on the priorities specified earlier.
    -h | --help                       	Help
    This script requires Python 2.6.9 and must run on the machine where DSC is installed.
  5. Add the generated DSA fabric configuration files to the DSC configuration:
    dsc config_fabrics -f ./output/xml_generated_file_name.xml
