During routine O&M, if an engineer finds that the system disk and some interface modules of a flash storage device are faulty, the engineer can directly remove and replace the faulty parts.

The statement is false. While many components in modern flash storage, such as interface modules, are hot-swappable, system disks are not. System disks (typically M.2 SSDs) contain the storage system's operating system and critical configuration data. Replacing a faulty system disk is a sensitive operation that requires the controller to be powered off or placed in a specific maintenance mode to prevent system instability or data corruption. Therefore, it cannot be "directly" removed and replaced during normal operation.

This is a True/False question. The statement is definitively false because replacing a system disk is not a direct, hot-swap operation, making option B (False) the correct choice.

1. Huawei OceanStor Dorado 8000 and 18000 V6 Parts Replacement Guide, "Replacing an M.2 SSD (for System Disks)". The procedure explicitly states: "Power off the controller enclosure where the M.2 SSD is to be replaced." This confirms that the component is not hot-swappable.

2. Huawei OceanStor Dorado 3000, 5000, and 6000 V6 Product Documentation, "Maintaining Hardware > Replacing Parts". The documentation consistently outlines that for critical internal components like system disks, a controller shutdown is a mandatory prerequisite for replacement.
