Hi Scott,
You have an old version of ipoibtools package (ipoib_ha.pl).
All issues you are talking about were fixed in the new version which
will be available in OFED-1.1-rc7.
You can also download it from SVN:
https://openib.org/svn/gen2/branches/1.1/src/userspace/ipoibtools

Thanks,

Regards,
Vladimir
