Eddy,
 QUERY ASYNCHRONOUS EVENT is the correct item.	The proposal that added 
this began as QUERY UNIT ATTENTION but ended up adding deferred errors as 
well as UA's so the name changed. This happened in proposal 07-224 
(http://www.t10.org/ftp/t10/document.07/07-224r1.pdf).	I am not sure when 
the name changed, but this is the history.

OSD2R4 has code 82h == QUERY UNIT ATTENTION. But SAM4 does not mention 
that TMF.
OSD2R4 does not mention QUERY ASYNCHRONOUS EVENT but SAM4 does.
I suspect that OSD2R2 should use QUERY ASYNCHRONOUS EVENT for 82h instead 
of QUERY UNIT ATTENTION.
