A financial customer has purchased several Huawei OceanStor Dorado series storage devices for mission-critical service deployment. SmartMigration is configured to migrate services from a source LUN to a target LUN without interrupting host services. Which of the following statements about this feature is false?
- A. When configuring this feature, you cannot use a LUN that has been mapped to an application server as the target LUN of a SmartMigration task.
- B. The higher the migration rate, the better the host service performance is. Therefore, the highest migration rate can be used when the host service load is heavy.
- C. The implementation of a SmartMigration task between heterogeneous storage systems depends on the LUN takeover function provided by SmartVirtualization.
- D. When configuring this feature, you must plan the capacities of the source and target LUNs. The capacity of the target LUN must be greater than or equal to that of the source LUN.
Answer: B
Explanation:
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.
