What is a volume move in ONTAP and when would you use it?

• A. Backing up a volume to cloud storage.
• B. Transferring a FlexVol from one aggregate or node to another to balance load or perform maintenance without downtime.
• C. Point-in-time data protection via a read-only snapshot.
• D. Automatically extending a volume when space is low.

Answer: (B)

Volume move in ONTAP relocates a FlexVol from one aggregate or node to another within the cluster. It runs in the background so client I/O remains available, meaning there’s no downtime during the move. This is used to rebalance data and workload across storage resources to improve performance or to move volumes off an older or failing aggregate when performing maintenance or hardware upgrades, all without interrupting access. It’s not about backing up data, point-in-time protection, or automatic volume growth—those serve protection or capacity expansion, not relocation of the volume.
