2.8   Command Processing Exceptions 
2.8.1  Overlapped tag 
The HDD recognizes that commands and tasks have been overlapped when it 
receives a command or task with the same tag from the same INIT as a command 
being executed or held in its queue, and abnormally terminates command or task 
processing. 
The execution of a command or task ends when the TARG reports RESPONSE to 
the INIT.  The execution of a command is also terminated with ABORT TASK, 
ABORT TASK SET, CLEAR TASK SET, LOGICAL UNIT RESET or HARD 
RESET.
