Backing Down Server Management

You cannot back down to a previous version of Server Management with PUT. You must use the cmicimageupdate utility from another EC2 instance managed by the CMIC. The steps below use Viewpoint as the example.

You cannot back down to a version earlier than the minimum version allowed on Teradata Database on AWS.

  1. Download the latest CMIC image to which you want to back down from TaYS.
    New and existing Teradata customers with on-premises Teradata systems can use TaYS to download the CMIC image.
  2. From the AWS Web Console, note the Private IP and Public IP of the CMIC instance.
    For information, see Connection Considerations.
  3. From your SSH client console, log onto the Viewpoint instance as ec2-user using the applicable AWS key pair.
    ssh -i  private key file  ec2-user@Viewpoint private-IP
    where:
    • The private key file is the private key file (.pem) of the AWS key pair specified when launching the instance.
    • The CMIC private-IP is private IP address of the CMIC instance.
  4. Run the configuration utility.
    ./cmicimageupdate --cmic  public-IP  --identity  private-key-file 
    --image  CMIC image.cif
    where:
    • The public-IP is public IP address of the CMIC instance.
    • The private-key-file is the private key file (.pem) of the AWS key pair specified when launching the instance.
    • The CMIC image is the name of the downloaded CMIC .cif file.
  5. When prompted, type yes to continue.
    The utility updates the CMIC version.
