AWS Backup for SAP HANA - Error in registeration process

Question

Hi all,

we have a problem setting up backup on AWS. 
We want to use the **AWS Backup** service and have followed this documentation. 
https://docs.aws.amazon.com/sap/latest/sap-hana/aws-backint-agent-backup.html#backint-backup-prerequisites

Now we are at the point: Register your SAP HANA database with AWS Systems Manager for SAP.

During registration we get the following error:

"Operation": {
        "Id": "xxxxx",
        "Type": "REGISTER_APPLICATION",
        "Status": "ERROR",
        "StatusMessage": "An internal error occurred.",
        "ResourceType": "APPLICATION",
        "ResourceId": "HANAREGISTRATIONTEST6",
        "StartTime": "2023-07-24T14:57:57.487000+00:00",
        "EndTime": "2023-07-24T14:58:27.523000+00:00",
        "LastUpdatedTime": "2023-07-24T14:58:27.523000+00:00"
    }
}

We have checked the prerequisite points listed in the doc and could not find any discrepancies.

Does anyone have any idea how to solve the error?

Thank you very much,

Hi Katz,

Have a look at https://boto3.amazonaws.com/v1/documentation/api/1.26.101/reference/services/ssm-sap/client/register_application.html

it gives 3 prereqs:

```
The SAP application you want to register with AWS Systems Manager for SAP is 
running on Amazon EC2.

AWS Systems Manager Agent must be setup on an Amazon EC2 instance along
 with the required IAM permissions.

Amazon EC2 instance(s) must have access to the secrets created in AWS Secrets 
Manager to manage SAP applications and components.
```

Do you satisfy them all ? #1 is obvious. #2 & #3 are the real ones. On #3, make sure to use the EC2 execution role that you assigned to your EC2 instances for it to work.

Best

Answer

Please take a look at SSM discovery log under /usr/bin/ssm-sap/logs/discovery.log 
The discovery log contains additional information on registration status which will be helpful to troubleshooting further.

Step-1: Prerequisites for SSM for SAP:
https://docs.aws.amazon.com/ssm-sap/latest/userguide/get-started.html

Step-2: Discovery and Registration SAP HANA Database using ssm-sap CLI:
https://docs.aws.amazon.com/ssm-sap/latest/userguide/register-database.html

Step-3: Setup AWS Backup for SAP HANA on Amazon EC2
