The HOST_COOLDOWN property, when set to enabled, will cause the server to enter cooldown mode when the host is powering off. Upon server poweroff, cooldown mode directs ILOM to monitor certain components to ensure that they are below a minimum temperature so as not to cause harm to the user. Once the components are below the minimum temperature, then the power is removed from the server, or if it takes longer then 4 minutes then the host will turn off.
-> set /SP/policy HOST_COOLDOWN=value
where value can be:
enabled – Server cools certain components before powering off.
disabled – Component temperatures are not monitored during power off.
