size=2>Vlad, thaks for the fast response. I have some followup questions
about configuring IPoIB HA, see below.</FONT><BR>
<P>
<FONT size=2>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?<BR> <BR><BR>
Yes, IP address should be the same. Actually the configuration of the secondary
interface does not matter.<BR> The
High Availability daemon reads the configuration of the primary interface and
migrates it between the interfaces in case of
failure.<BR> <BR> <BR>If
I don't have an ifcfg-ib1 file, then ipoib_ha.pl won't start.</FONT></P>
<P><FONT face=Arial color=#0000ff size=2>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.</FONT></P>
