MultiNICA agent
The MultiNICA represents a set of network interfaces, and provides failover capabilities between them. You can use the agent to make IP addresses on multiple-adapter systems highly available.
The IPMultiNIC agent depends upon the MultiNICA agent to select the most preferred NIC on the system. IPMultiNIC brings the virtual IP online or offline. However, if the MultiNICA resource changes its active device, the MultiNICA agent handles the shifting of IP addresses.
If a NIC on a system fails, the MultiNICA agent selects another active NIC. The agent then shifts the virtual IP address to the newly selected active NIC. Only in a case where all the NICs that form a MultiNICA agent fail, does the virtual IP address shift to another system.
If you associate an interface with a MultiNICA resource, do not associate it with any other MultiNICA or NIC resource.
If the same set of interfaces must be a part of multiple service groups, configure:
A MultiNICA resource in one of the service groups, and
The Proxy resources that point to the MultiNICA resource in the other service groups.
The MultiNICA agent can operate in two modes:
With sufficient IP addresses, use PM.
The IPMultiNIC and MultiNICA agents support Linux bonds.
The IPMultiNIC and MultiNICA agents support IPv4 and IPv6.
