Enable Negotiated cluster failover on NIC failure

In FAS clusters the default option is that a single network card failure will not result in a cluster failover


You can change this by enabling NICs for Negotiated Failover in the RC file.


Here's how to do this:


First set the cf option "cf.takeover.on_network_interface_failure" to on, next set the policy type:

cf.takeover.on_network_ interface_failure.policy any_nic (default is all_nics)


When these options are enabled you can specify through the ifconfig command that Negotiated Failover should be

enabled for certain nics by using the "nfo" parameter:


ifconfig e0a 192.168.100.20 netmask 255.255.255.0 nfo


Be aware that enabling the "cf.takeover.on_network_interface_failure" option when the

option cf.giveback.auto.enable is also set to on could result in an infinite loop of takeovers and givebacks

This will continue until either cf.giveback.auto.enable is disabled or the network is healed.
