If you receive licensing errors during or after deployment, access the AWS CloudWatch logs (look for log group Teradata/DBS/stack-name and log stream telm_stack-name).
If a problem occurs during deployment, the stack is rolled back and activated licenses are automatically revoked.
During deployment, activated licenses are automatically revoked if a failure occurs. If activated licenses did not get revoked, you can revoke them manually. After revoking the licenses from the instances, you can delete the AWS CloudFormation Stack.
Following are examples of errors and possible remedies:
| Errors | Remedies |
|---|---|
| License doesn't have requested tier or term | Make sure the term you selected when you deployed matches the email confirmation. The Vantage license tier is determined when you select the AMI. |
| Not enough tcores available | If additional TCores are needed, contact your Teradata Account Team. |
| DBValidateLicense | In AWS CloudWatch logs, look for the log group: /aws/lambda/stack-name-DBCheckLicenseFunction |
| Not all nodes activated successfully | Contact Teradata Services. |
