FYI:  Just last month at the T10 committee my proposal was approved for
inclusion into SAM-2, and SPC-2.  It defines a new status value of TASK
ABORTED.  When enabled via a mode page, this new status is returned to an
initiator if his I/O was terminated because of a task management function
performed by another initiator.  So, if initiator A sends down a LU Reset,
all of initiator B's I/Os would be returned to him with a Task Abort status
so he knows what happened.  See T10/00-229r3 for details.
