Rodrigo,
Thank you for the post.
I am currently running version 8.0.2 on our array. When running another Storage vMotion and issuing the "stats show vstorage" command I receive the following output:
vstorage:vfiler0:xcopy_copy_reqs:0
vstorage:vfiler0:xcopy_abort_reqs:0
vstorage:vfiler0:xcopy_status_reqs:0
From this I am guessing VAAI is not working correctly.
