Never mind.  I found this reported on the target-devel mailing list.   Not an 
FCoE issue.

> I have a target set up in vn2vn mode with two iblock target luns.
> If I delete either lun 0 or lun 1, a REPORT LUNS command from the client acts

> It reports either LUN 1 or LUN 0, whichever is remaining.
