The question focuses on the running statuses of remote replication pairs in Huawei’s flash storage

systems, such as OceanStor Dorado. The *HCIP-Storage V5.5 Training Material (Module 4: Storage

Design and Implementation)* details the remote replication feature and its statuses. The material

states: “When the pair running status is ‘Normal,’ the remote replication pair is fully synchronized,

meaning data between the primary and secondary LUNs is consistent, and synchronization is

complete.” This matches option C.

- Option A: Incorrect. The training material indicates that if a pair is deleted from one site, causing

inconsistency, the status may not necessarily change to “To be recovered.” Instead, it may require

manual intervention or reconfiguration, and “To be recovered” is typically associated with link

failures or incomplete synchronization, not deletion.

- Option B: Incorrect. The “Split” status occurs when the pair relationship is interrupted, but it can be

due to manual intervention or automatic triggers (e.g., link failure). The parenthetical “not manually”

is misleading, as the material does not restrict “Split” to non-manual causes.

- Option D: Incorrect. The “To be synchronized” status indicates that the pair is preparing for

synchronization but is not yet consistent. There is no requirement to manually disconnect the pair for

single LUN service needs, as the system can operate with the primary LUN independently during this

state.

Thus, option C is the only accurate statement based on official documentation.
