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
