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.

Explanation:

The -p option requests that reallocation of user data take place on the physical blocks in the
aggregate, but thelogical 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 ona volume with snapshots. It may also reduce the amount of data that needs to
be transmitted by SnapMirror onits next update after reallocation is performed on a SnapMirror
source volume.
