Create a System Image | Teradata VantageCloud Enterprise on AWS (DIY) - Creating a System Image - Teradata® VantageCloud Enterprise on AWS

Use this procedure to create a new system image, such as in the restoration process of a node failure or for deploying new instances for scaling out. If this image is not created, the software on the recovered instance will not match and the database cannot start if a node failure occurs. In addition, you must create a new system image after upgrading software or adding the system to Teradata QueryGrid.

When a new system image is created, Vantage re-provisions hot standby nodes based on the new system image.

Creating a system image requires a reboot of the target node used to create the image. On a single-node system, the system image creation process automatically targets the one available node. After the system reboots, monitor the status of the instance using the AWS CloudWatch logs in /var/log. If you do not complete this procedure, Vantage uses the image generated when you deployed the instance.

When the software upgrade script runs as a part of the following procedure, it creates a temporary d2.xlarge instance and a 350 GB EBS volume. This instance and volume is automatically deleted, but you will incur a minimal charge. Software upgrades are stored in an AMI in your account for node failure recovery purposes or if you scale out. Charges for this AMI vary per customer.
