| Secondary Node Kill | Process | The Secondary Node Kill test examines cluster resilience by forcefully terminating HANA processes on the secondary node using the kill -9 signal. The test validates that the primary node maintains normal operation while the secondary node undergoes recovery, ensuring cluster stability and proper data synchronization after the recovery process completes. |[node-kill.md](./pseudocode/node-kill.md)|

| Secondary Echo B | System | The Secondary Echo B test simulates an uncontrolled system crash on the secondary HANA node by executing the 'echo b' command, triggering an immediate reboot without proper shutdown procedures. The test validates that the primary node maintains operation, verifies cluster stability, and ensures system replication resumes correctly after the secondary node recovers. |[echo-b.md](./pseudocode/echo-b.md)|

| Filesystem Freeze | Storage | The Filesystem Freeze test validates cluster behavior when the primary node's filesystem becomes unresponsive. It simulates a storage issue by freezing the filesystem on the primary node running HANA database, which triggers automatic failover to the secondary node. The test verifies proper cluster reaction, resource migration, and data consistency after recovery. |[freeze-filesystem.md](./pseudocode/freeze-filesystem.md)|

| SBD Fencing | Fencing | Validates cluster fencing mechanism by killing the SBD inquisitor process on the primary node. Tests proper fence detection, node isolation, and automated failover to ensure cluster integrity during hardware or communication failures. |[sbd-fencing.md](./pseudocode/sbd-fencing.md)|
