NDVM is supported on which type of volumes?

• A. NAS volumes
• B. Root Volumes
• C. All volumes
• D. SAN volumes

Answer: (D)

NDVM stands for Non-Disruptive Volume Migration, a feature that lets you move a data volume without taking it offline or interrupting I/O. This capability is available for SAN volumes, which are block-based LUNs presented to hosts. The migration happens at the storage layer and is transparent to the hosts, so running clients don’t notice. NAS volumes are file-based and exported over network protocols; migrating them non-disruptively would involve changing the underlying file system and exports, which isn’t supported. Root volumes are tied to the system’s operating environment and require a stable OS image, so they aren’t eligible for NDVM either. So, NDVM is supported on SAN volumes.
