Observe the following guidelines for IPMP groups in an Open HA Cluster configuration:
Link-based IPMP groups –At cluster installation time, automatically created IPMP groups are configured as link-based groups. If you want an IPMP group to be probe based, you must manually edit the /etc/hostname.adapter file on each node to add test addresses.
LogicalHostname and SharedAddress resources – If you configure a LogicalHostname or SharedAddress resource with a hostname that uses a single adapter, the automatically created IPMP group for that adapter is configured for link-based monitoring. You can afterwards modify the /etc/hostname.adapter files for these IPMP groups to make them probe based.
