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

Vlad, thaks for the fast response. I have some followup questions about configuring IPoIB HA, see below.
3) I got IPoIB HA working on SLES 10, but the documentation is a little lacking. Looks like I have to put the same IP address in ifcfg-ib0 and ifcfg-ib1, is this correct?
Yes, IP address should be the same. Actually the configuration of the secondary interface does not matter.
The High Availability daemon reads the configuration of the primary interface and migrates it between the interfaces in case of failure.
If I don't have an ifcfg-ib1 file, then ipoib_ha.pl won't start.
If I don't have an ifcfg-ib1, then ipoib_ha.pl won't start. I would prefer to not configure ifcfg-ib1 since I don't plan to use it.
# ipoib_ha.pl --with-arping --with-multicast -v

If I put different IP addresses in ifcfg-ib0 and ifcfg-ib1, then the ifcfg-ib1 IP address is used for both ib0 and ib1!

Notice how both ib0 and ib1 have the IP address from ifcfg-ib1. This contradicts this info from ipoib_release_notes.txt:
b. The ib1 interface uses the configuration script of ib0.
