Over the weekend we've just finished an experiment of changing HANA SID. The research we are doing includes:
- Procedures to change HANA SID
- Will hardware key change after changing HANA SID
- How licenses work after HANA SID changed
So, first of all, let's backup the system and start this experiment!
Since we are running VMWare ESXi, so the offline backup is very straightforward, simply shutdown HANA DB, then shutdown OS (Redhat Linux), then do a VM clone
Here we have an question: based on our experience, in the old days, when we installed multiple SAP systems on the same VM host but different VM guest systems, the hardware keys across these VM guest systems actually are the same. This kind of behavior means, for SAP systems, the calculation of hardware keys are purely based on the actual hardware, such as system board, NICs and so on. I believe you may also experienced the scenarios like changing the Network Card will void the existing license, right?
Will HANA DB calculate the hardware key the same way? Will the cloned system be running OK if we bring it up? Let's find out later.
