Initializing a DSC VM

After deploying a DSC VM, you must log on to the VM and initialize the DSC.
  1. From the Azure portal, note the following of the Viewpoint VM:
    • The Private IP address.
    • If applicable, either the Public IP or Public DNS.
  2. From the SSH client console, connect to the VM by logging on to the DSC VM using the same authentication type you chose when you deployed the VM using the Teradata ecosystem solution template or the single VM from an image.
    Authentication type Action
    SSH public key Enter the following:
    # ssh -i ssh-private-key.pem azureuser@VM-public-IP-address or VM-public-DNS-address
    where:
    • The ssh-private-key is the private key file (.pem) specified when you deployed the VM.
    • The azureuser is the user name specified when you deployed the VM.
    • The VM-public-IP-address or VM-public-DNS-address is the DNS host name or public IP address of the DSC VM.
    Password Enter the following:
    # ssh azureuser@VM-public-IP-address or VM-public-DNS-address
    Password: password
    where:
    • The azureuser is the user name specified when you deployed the VM.
    • The VM-public-IP-address or VM-public-DNS-address is the DNS host name or public IP address of the VM.
    • The password is the password specified when you deployed the VM.
  3. Switch to the root user environment.
    # sudo su -
  4. Initialize DSC on the VM, either interactively or non-interactively.
    Note:
    For either of the following options change the DSC repository password to the Azure VM ID.
    Option Description
    Interactively
    1. Run dsu-init without an argument
      .# /opt/teradata/client/version/dsa/commandline/dsu-init
      where version is the version of DSC you are initializing.
    2. Enter the private-DNS of the Viewpoint VM to be used with DSC at the prompt to provide information for an internal Teradata Database repository that DSC uses to store its metadata.
    Non-interactively
    1. Run dsu-init with any of the optional arguments.
      # /opt/teradata/client/version/dsa/commandline/dsu-init -v vp private-DNS
      where:
      • version is the version of DSC you are initializing.
      • vp private-DNC is the private-DNS of the Viewpoint VM to be used with DSC.

      Automated scripts initialize DSC on the VM without further input from you.

  5. Obtain the DBC and DSUADMIN passwords.
    The default setting of these passwords is only alphanumerics of this vmID.
    1. Run vmuid.py.
      # python /opt/teradata/client/version/dsa/commandline/vmuid.py
      where version is the version of the DSC you are initializing.
    2. Remove the dashes that resulted from running the script.
DSC is ready to use. The script sets the repository target group. The repository backup will be stored on the local machine at /var/opt/teradata/dsc/pathRepo. For information on how to configure systems, storage backup applications, and target groups for premium storage to run operational jobs, see Data Stream Utility Installation, Configuration, and Upgrade Guide for Customers and Teradata Data Stream Architecture User Guide.

If you plan to use the BAR portlets in Teradata Viewpoint, see Configuring a Teradata Viewpoint VM for DSC.
