An industry customer has purchased a Huawei OceanStor Pacific 9950 scale-out storage device for service...

This question tests knowledge of disk status indicators in Huawei OceanStor Pacific 9950 systems. The *HCIP-Storage V5.5 Training Material (Module 5: Storage System Maintenance and Troubleshooting)* provides details on disk module indicators: “A steady yellow location indicator on a main storage disk module indicates that the disk is faulty or about to fail. This status signals that the disk requires attention, such as replacement, to prevent data loss or service disruption.” The material further clarifies the following for other options:

- Option A: Incorrect. A blinking yellow indicator, not a steady one, typically indicates that the disk is being located (e.g., via DeviceManager or CLI).

- Option B: Incorrect. A steady green indicator signifies that the disk is running properly.

- Option C: Incorrect. A powered-off disk would have no indicator light or a specific power-off signal, not a steady yellow light.

Thus, option D accurately describes the disk’s status.
