We already know HANA High Availability Concept.

I wanted to test this HANA High Availability feature in My Landscape practically and I completed the testing successfully.

I would like to share this Testing experience.


HANA Landscape:


It is 3 Node Scale-Out HANA Landscape.

Node-1:     240f1d253      Master

Node-2:     5d67d765b    Slave

Node-3:     89a40ea9a     Standby       

Now all the 3 nodes are running fine.

Assume The Slave Node – 5d67d765b was getting crashed.

(For Testing Scenario, I manually stopped Slave node – 5d67d765b using HDB STOP operation)

What happened Next  ???

Immediately Stand by node – 89a40ea9a  took over the Slave node role and

Slave node – 5d67d765b changed as standby.

After few seconds, Stand by node – 5d67d765b back to running status automatically.

I hope this blog might be helpful for you to understand the High Availability feature practically 🙂
