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 VM 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 Azure.

  1. Download the latest CMIC image to which you want to back down from Teradata Support.
    New and existing Teradata customers with on-premises Teradata systems can use Teradata Support to download the CMIC image.
  2. From the Azure portal, note the private IP and public IP of the CMIC VM.
  3. From the SSH client console, connect to the VM by logging on to the Server Management VM using the same authentication type you chose when you deployed the VM.
    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 Server Management 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.
  4. Run the configuration utility.
    ./cmicimageupdate --cmic  private-CMIC-IP --sshuser username --identity  private-key-file 
    --image  CMIC image.cif
    where:
    • The public-IP is public IP address of the CMIC VM. Although a public IP address can be used a private IP address is preferred.
    • The private-key-file is the private key file (.pem) of the key pair specified when deploying the VM.
    • 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.
