TencentDB for Redis supports multi-availability zone deployment. Users can deploy their businesses in multiple availability zones to improve the high availability of systems. Users can use primary-secondary nodes unavailability fault in TencentDB for Redis provided by Tencent Smart Advisor-Chaotic Fault Generator to simulate such scenes so that disaster recovery and overall high availability of their business systems can be verified.

Step 3: Experiment Execution
1. Try to log in to a TencentDB for Redis instance through CVM.
2. Go to Experiment Details. In the Experiment Action Group, click Execute to start executing an experiment.
3. After fault injection, log in to a TencentDB for Redis instance through CVM once again.
