Data ONTAP is configured by default to initiate a takeover immediately if the partner node panics. This shortens the time between the initial failure and the time that service is fully restored because the takeover can be quicker than the recovery from the panic, although the subsequent giveback causes another brief outage.
The cf.giveback.auto.after.panic.takeover option can be used to disable this automatic giveback.
on enables immediate takeover of a panicked node. This is the default value.
off disables immediate takeover of a panicked node. If you disable this option, normal takeover procedures apply: if a node panics and stays down without sending messages to its partner for 15 seconds, the partner then automatically takes over the failed node.
