My mistake.  From the smartctl man page regarding "-l offline":

"The effects of this test are visible only in that it updates the SMART 
Attribute values, and  if  errors  are found they will appear in the 
SMART error log, visible with the ´-l error´ option."

If you didn't get any errors (and I see from your earlier e-mail that 
you didn't have any before), then the test ran clean.  You can also use 
"smartctl -t long /dev/sda" -- I haven't been able to really determine 
which is the more thorough test.  This one does log to self-test long.

And yes, the "-X" option is really to abort a running test, as in "I 
didn't mean to run that", not for normal termination.
