In Huawei FusionCompute, what is the correct sequence for deleting storage resources?

In Huawei FusionCompute, the correct sequence for deleting storage resources follows a logical process based on the dependencies and relationships between different storage components. The proper order, as indicated in the correct answer, starts with the first step of deleting the storage pool.

1. Delete the storage pool: This is the overarching container for various storage resources. Before removing any components that depend on the pool, it should be deleted first to ensure that nothing remains that is dependent on it.

2. Delete the datastore: After the storage pool is removed, the next step is to take out the datastores that reside within that pool. The datastore relies on the pool, so it makes sense to delete it only after the pool is gone.

3. Delete the LUNs (Logical Unit Numbers): Once the datastores are removed, the LUNs that might reside within them should also be deleted. LUNs are typically connected to the datastores, so they should be removed afterward.

4. Delete the storage service: Finally, the storage service, which coordinates and manages these resources, is taken down last as it does not serve any purpose once the underlying storage resources it manages have been deleted.

This sequence ensures that
