Troubleshoot high availability SAP HANA deployments

This section provides guidance for troubleshooting SAP HANA high availability deployments.

A healthy status of SAP HANA system replication is a foundational requirement for the cluster solution to maintain stability. If SAP HANA system replication doesn't have any dependencies on cluster solution, it can be independently verified using SAP Note 2518979 - HANA : how to check system replication status.

For manual deployment, there must not be any underlying issues within the cluster member systems for their continuous system replication and takeover procedures. This must be independently verified before integrating a cluster solution for automation. SAP HANA system replication depends on various factors for functioning smoothly. To troubleshoot any issues, see Troubleshoot System Replication.

Alternatively, you can use guided troubleshooting provided by SAP. For more information, see SAP HANA Troubleshooting. You can also chat with experts or open an incident with SAP. For a speedy resolution, collect the relevant SAP HANA logs as per SAP Note 2934640 - HANA and Replication - Collecting Support Data for Replication / Network related Tickets. The fullsysteminfo-dumps log must be collected from all the cluster member systems for a complete analysis.
