Which operation is incorrect when creating a new disk in Huawei FusionCompute?

The operation in option C is incorrect due to the nature of raw device mapping (RDM) and its compatibility with virtual disk configurations. When creating a new disk in Huawei FusionCompute, the ability to set a disk mode to “independent-non-persistent” while having the raw device mapping set to “supported” is not a valid combination. This is because independent disk modes are typically not associated with RDM configurations that would be required for certain operational capabilities.

In contrast, the other options present valid configurations. For example, setting the disk type to "normal" and choosing "independent-non-persistent" allows for temporary data storage that does not persist after VM power off, which is a common practice for testing purposes. Furthermore, having a disk configuration mode set to "Thin" while using either form of independent mode is generally accepted as it allows for efficient use of storage space.

In summary, option C's requirement clashes with accepted configurations for disk modes and mappings, leading to the operation being deemed incorrect in the context of creating a new disk in Huawei FusionCompute.
