I am trying to figure out what the expected behavior should be under the
following circumstances:
1.	Two different hosts send a Target Reset back to back.  Should
the target return a function complete to the first, last, or both Target
Resets?
2.	The same host sends a Target Reset back to back.  Should the
target return a function complete to the first, last, or both Target
Resets?
3.	A target receives a Logical Unit Reset and while processing it
the target receives a Target Reset from a different host.  Should the
target return a function complete to the Logical Unit Reset, the Target
Reset, or both?
4.	A target receives a Logical Unit Reset and while processing it
the target receives a Target Reset from the same host.  Should the
target return a function complete to the Logical Unit Reset, the Target
Reset, or both?
5.	Two different hosts send a Logical Unit Reset back to back to
the same LUN.  Should the target return a function complete to the
first, last, or both Logical Unit Resets?
6.	Two different hosts send a Logical Unit Reset back to back to
the same LUN.  Should the target return a function complete to the
first, last, or both Logical Unit Resets?

I would appreciate any responses.

Thanks
