NDVM support is available for which of the following volumes?

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

Answer: (B)

NDVM, or nondisruptive dynamic volume management, is a feature that applies to SAN (block-based) volumes. It enables certain volume operations to be performed online without interrupting I/O to hosts, which is essential for volumes presented to hosts as LUNs in a SAN environment. NAS volumes store data at the file level and are accessed via protocols like NFS or SMB, so they don’t use the block-level management NDVM provides. Root volumes are system boot volumes and aren’t handled by NDVM either. Therefore, NDVM support is available for SAN volumes.
