Sap Launch Wizard fail

When you find error in Launch Wizard, you can check the details of the errors as follows:

• Go to the "CloudFormation Console" to see under Event Tab to nail down the root cause.
• When the failure is happening within EC2 instance (during HANA installation), then you can do SSH into the EC2 instance to look at the logs and find the root cause.

In order to do this, ensure that you do not tick "Enable rollback on failed deployment" when you kick off the Launch Wizard.

As the above advises, please check where the stack is failing under the CloudFormation -> Event Tab -> Failed events.

To check why the HANAMasterInstance deployment may be failing you will need to check the logs contained on the instance. After unchecking "Enable rollback on failed deployment" you can find instance level script ouput in */root/install/scripts/log * during the deployment process, when the instances are being launched and configured. The name of the log file is install.log. To check the progress of the deployment, you can log in to an instance as soon its instance state is listed as running. When the deployment is finished, the log files are moved to /tmp. In addition to the install.log file, the install.dbg file includes additional error information in case of failure scenarios. See LaunchWizard for SAP Troubleshooting for more information.
