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.
E. Dont run it on files, volumes, and LUNs that are in an aggregate created by a version of ONTAP earlier than 7.2.

The -p option requests that reallocation of user data take place on the physical blocks in the aggregate, but the logical block locations within a flexible volume are preserved.
Aggregate reallocation is not supported on aggregates created prior to Data ONTAP 7.2.
Using the -p option may reduce the extra storage requirements in a flexible volume when reallocation is run on a volume with snapshots. It may also reduce the amount of data that needs to be transmitted by SnapMirror on its next update after reallocation is performed on a SnapMirror source volume.
