Mandatory Parameters for Creating a LUN Snapshot in Huawei Storage
Short answer
CD The mandatory parameters for creating a LUN snapshot are the Save path (to store delta data) and the Snapshot name (as the unique identifier).
Question
Key Takeaways
The main trap is confusing optional metadata or default operational states with mandatory configuration parameters needed to instantiate the snapshot object.
This question identifies the mandatory parameters required when creating a LUN snapshot in Huawei OceanStor systems. The correct options are the Save path and Snapshot name.
Common mistake: Candidates often select Option A (Whether to activate the snapshot) because they believe manual activation is part of the setup process. However, activation is usually automatic or handled separately, making it non-mandatory for the creation step itself.
Expert Analysis
In Huawei OceanStor storage systems, a Logical Unit Number (LUN) snapshot is a point-in-time copy of data. When creating a snapshot via the management interface or CLI, specific parameters are required to define and manage this object.
The most common trap is assuming that operational states like activation status (Option A) must be explicitly set during creation. In reality, snapshots are typically created in an inactive state by default or are automatically activated upon successful creation depending on the policy; it is not a mandatory user-input parameter for the initial creation command. Similarly, while metadata exists, a description (Option B) is optional metadata, not a structural requirement.
The critical mandatory fields are:
- Snapshot Name (Option D): This is the unique identifier for the snapshot within the LUN context. Without a name, the system cannot reference or manage the snapshot later. It is strictly required.
- Save Path / Location (Option C): In Huawei terminology, creating a snapshot requires specifying where the delta data (the changes from the source LUN) will be stored. This is often referred to as the 'location' or 'path' in the context of the storage pool or specific resource group where the snapshot space resides. You must designate the target location for the snapshot data.
Therefore, the system mandates a name to identify it and a path/location to store its data. Options A and B are either default behaviors or optional descriptive fields.
Exam Strategy
When dealing with storage object creation questions, distinguish between 'identifiers/storage locations' (always mandatory) and 'metadata/operational flags' (often optional or default). For Huawei exams, always verify if a setting is a prerequisite for existence versus a post-creation action.
