Appendix B: Troubleshooting - Scale-Out Computing on AWS

Appendix B: Troubleshooting

If the Scale-Out Computing on AWS solution stack fails when being deployed into your account, verify the following:

  • You received a region resource approval email. When deploying Amazon Elastic Compute Cloud (Amazon EC2) resources for the first-time automated approval is required. If you did not receive the email, wait five minutes for the email and try again.

  • Verify that you have the correct inbound restrictions set for the scheduler instance security group.

  • Verify the Stack Name parameter is less than 24 characters and does not include any capital letters.

  • You launched this solution in an AWS Region that has at least three Availability Zones. This solution uses three Availability Zones to maximize the resources users have for submitting jobs.


    To help make it easier to troubleshoot, we recommend disabling the rollback on failure feature in the AWS CloudFormation template.

    You can also find additional troubleshooting help in the project documentation.
