HANA instance stays in status "Prepared" and is not activated

Hello,

I created an instance of "AP ERP Foundation Extension powered by SAP HANA" on AWS through the Cloud Appliance Library.

Two virtual machines should be created for this instance:

• SAP ERP 607 on SAP HANA SPS07
• SBOP BI Platform 4.1

The SBOP virtual machine is created - i can also see it in the AWS Console - started. Status in CAL is active  & green

The ERP virtual machine remains in status "Prepared" in CAL.  This does not change and i can't see any corresponding instance in AWS.

Overall status of the instance : "Undefined"

I tried some "activate/suspend" cycles hoping that this would help but it remains unchanged.

What does the "Prepared" status actually mean for a virtual machine?

Are additional steps required to trigger generation of the ERP-HANA virtual machine on AWS?

Thanks for any useful advise,

Frank
