What is the correct sequence of operations for creating a disk using IP SAN in Huawei FusionCompute?

The correct sequence for creating a disk using IP SAN in Huawei FusionCompute is rooted in the logical flow of establishing necessary resources and configurations before creating the disk itself.

Initially, by adding a storage port on the host, you enable communication between the Huawei FusionCompute and the storage system. This step is crucial as it establishes the pathway through which data can be transferred to and from the storage. Once the storage port is set up, the next step is to create a storage resource. This establishes an organized environment where the storage can be effectively managed.

After the storage resource is created, adding a data store is the subsequent action. The data store represents a container for storing disks and is essential for managing disk allocation and access within the environment. Finally, with the storage port, resource, and data store in place, you can create the disk. This final step utilizes the previously established configurations to allocate the necessary capacity and parameters for the disk.

This sequence ensures that all prerequisites are met before attempting to create the disk, thereby streamlining the process and reducing potential errors that might occur if attempted in a different order.
