The MultiNICB works with the IPMultiNICB agent. Allows IP addresses to fail over to multiple NICs on the same system before VCS tries to fail over to another system. You can use the agent to make IP addresses on multiple-adapter systems highly available or to monitor them.
When you use the MultiNICB agent, you must configure the NICs before putting them under the agent's control. You must configure all the NICs in a single MultiNICB resource with the IP addresses that are in the same subnet.
You need to set the MONITOR flag for each NIC that the agent controls. Use the ifconfig command to set the flag. For example:
HP-UX and Solaris: If multiple service groups have IPMultiNICB resources associated with the same MultiNICB resource, only one group should have the MultiNICB resource. The other groups can have a proxy resource pointing to it.
