Jody, Can you check whether sgpdd survey will preserve and/or control I/O alignment. It's been brought to my attention that more recent DDNs are sensitive to alignment, which didn't seem to be an issue when I first wrote that script. First thing to do would be to check the DDN stats offset.
Cheers,
Eric
