Similar to the alarm analysis method, the replacement method can be used to locate and rectify any type of faults for Huawei converged storage, and has no special requirement for maintenance personnel.
The *HCIP-Storage V5.5 Training Material (Module 5: Storage System Maintenance and Troubleshooting)* discusses fault rectification: “The replacement method, which involves swapping components to identify faults, is effective for hardware issues but not suitable for all fault types (e.g., software or configuration errors). It requires trained maintenance personnel with knowledge of system architecture and safety procedures to avoid service disruptions.” The statement that it can address any fault type and has no special personnel requirements is false, as the method is limited and demands expertise.
