Introduction
This blog post walk’s you through the step by step process for SAP HANA 2.0 high availability setup. How to add a stand by host.
A distributed HANA(scale out) setup need 2 servers (one worker, another standby).
Note : Both Host1 and Host2 server’s date and time should be same.
Below mentioned are the steps that need to followed for high availability setup.
Host 1 (worker)
SID = HDB
Instance Number = 00
Hostname = ca
Host Role = worker
Host 2 (Standby)
SID = HDB
Instance Number = 00
Hostname = portal
Host Role = Standby
NFS(network file system) is used to share the files between host1(worker) and host2(standby) (/hana/log, /hana/shared, /hana/data)
*Operating system used SUSE Linux SP15
- Configure NFS server on host1 (ca)
- Configure NFS client on host2 (portal)
- Install SID= HDB, master node (Host1) using installation media’s HDBLCM
- On master node(Host1) execute action configure_internal_network (using resident HDBLCM) "./hdblcm --action=configure_internal_network"
- Inter-service communication is configured now
- On second node (Host2) navigate to /hana/shared/SID/hdblcm and execute "./hdblcm" to add host to master node
- The below screen, shows services after adding standby node
- Hosts – after adding standby node:
