Vlad,
I filed a bug for these issues.
1) If I start IPoIB HA with ib0 IB port shut down (from IB switch) and ib1 IB port enabled, then IPoIB does not work because "ip monitor link all" does not report NO-CARRIER at startup like ipoib_ha.pl is looking for. This is a major hole.Fixed, will be updated in OFED-1.1-rc7.
2) /etc/init.d/openibd runs ipoib_ha.pl with its stdout and stderr redirected to /dev/null, should we run with -v for verbose instead and redirect log file to /var/log?
# fgrep ipoib_ha.pl /etc/init.d/openibdAdded /var/log/ipoib_ha.log and the verbose output of ipoib_ha.pl redirected into this log file.
ipoib_ha.pl -p ${PRIMARY_IPOIB_DEV} -s ${SECONDARY_IPOIB_DEV} --
with-arping --with-multicast > /dev/null 2>&1 &
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.
# pwd
/etc/sysconfig/network
# cat ifcfg-ib0
DEVICE=ib0
BOOTPROTO=static
IPADDR=192.168.2.46
NETMASK=255.255.255.0
>
# cat ifcfg-ib1
DEVICE=ib1
BOOTPROTO=static
IPADDR=192.168.2.46
NETMASK=255.255.255.0

4) If I shutdown ib0 IB port, I see this from "/usr/local/ofed/bin/ipoib_ha.pl -v --with-arping --with-multicast"
Use of uninitialized value in concatenation (.) or string at /usr/local/ofed/bin/ipoib_ha.pl line 287.Fixed.
