to provide more cooling, and decreasing the fan speed when cooling is sufficient. If a fan failure
occurs, fan operation policies might increase the speed of the other fans, record the event in the
IML, or turn on LED indicators.
In non-redundant configurations, or redundant configurations where multiple fan failures occur,
the system might be incapable of providing sufficient cooling to protect the server from damage
and to ensure data integrity. In this case, in addition to the cooling policies, the system might
start a graceful shutdown of the operating system and server.
