Which scenario is best described for using a volume move?

• A. During maintenance to balance load or perform maintenance without downtime.
• B. When creating a new volume.
• C. When upgrading the entire cluster firmware.
• D. When converting volumes from HDD to flash.

Answer: (A)

Volume move lets you relocate a volume from one aggregate to another while the volume remains online, so clients keep accessing data during the change. This capability is used primarily to balance capacity and performance or to perform hardware maintenance without taking the volume offline. By moving the volume to a less loaded or new aggregate, you can free resources, adjust storage layout, or service equipment, all without interrupting I/O.

Creating a new volume is done with a volume creation operation, not a move. Upgrading the entire cluster firmware is a separate maintenance task at the cluster level and not about relocating a specific volume. Moving a volume to a different tier (for example, from HDD to flash) could occur as part of a tiering or re-architecting effort, but the scenario that best describes a volume move’s purpose is performing maintenance or balancing load without downtime.
