A financial customer has purchased several Huawei OceanStor Dorado series storage devices for mission-critical service deployment. SmartMigration is…

The SmartMigration feature in Huawei OceanStor Dorado enables seamless data migration between

LUNs, as detailed in the *HCIP-Storage V5.5 Training Material (Module 4: Storage Design and

Implementation)*. Let’s analyze each option:

- Option A: True. The material states: “SmartMigration between heterogeneous storage systems

relies on SmartVirtualization to take over the source LUN, ensuring compatibility and seamless

migration.”

- Option B: True. The material confirms: “The target LUN capacity must be greater than or equal to

the source LUN capacity to accommodate all data during migration.”

- Option C: True. The material notes: “A LUN already mapped to an application server cannot be used

as the target LUN for SmartMigration, as it would disrupt existing mappings.”

- Option D: False. The material explains: “The migration rate affects system resources. Setting the

highest migration rate under heavy host service load can degrade performance due to resource

contention. The rate should be adjusted based on load to minimize impact.” This makes the

statement false, as high migration rates are not recommended during heavy loads.

Thus, option D is false.
