What are three true statements about physical reallocation of data added in ONTAP 7.3? (Choose three.)

• A. Use reallocate -p pathname to run the physical reallocate.
• B. Use aggr reallocate -p pathname to run the physical reallocate.
• C. Reinitialize any SnapMirror relationship for the new physical geometry.
• D. Volume Snapshots do not need to be deleted for the reallocate to run effectively.

Answer: (A)

Physical reallocation reorganizes data blocks within a volume/aggregate to improve space usage after expanding storage and changing the data layout. To perform this reallocation for a specific data path, you issue the per-path reallocation command with the -p option and provide the pathname. This is the supported method for targeting a particular portion of the data layout in ONTAP 7.3 7-Mode.

The alternative form that mentions an aggregate-level command isn’t the correct syntax for this operation in 7.3; the per-path approach via reallocate -p pathname is how you specify what to reflow. Reinitializing SnapMirror relationships isn’t required by a reallocation—the operation stays within the source’s data layout and doesn’t mandate resetting mirrors. Similarly, you don’t have to delete Volume Snapshots to run the reallocate; snapshots are preserved and do not need to be removed for the reallocation to proceed.
