Restore the Host Power State at Restart
Use the /SP/policy HOST_LAST_POWER_STATE property to control the behavior of the server
after an unexpected power outage. When external power is restored, the Oracle ILOM SP starts
to run automatically. Normally, the host power is not turned on until you use Oracle ILOM to
turn it on.
Oracle ILOM records the current power state of the server in nonvolatile storage. If the
HOST_LAST_POWER_STATE policy is enabled, Oracle ILOM can restore the host to the previous
power state. This policy is useful in the event of a power failure, or if you physically move the
server to a different location.
For example, if the host server is running when power is lost and the /SP/policy
HOST_LAST_POWER_STATE property is set to disabled, the host server remains off when power is
restored. If the /SP/policy HOST_LAST_POWER_STATE property is set to enabled, the host server
restarts when the power is restored.
At the Oracle ILOM prompt, type:
-> set /SP/policy HOST_LAST_POWER_STATE=enabled
where value can be:
■
enabled – When power is restored, returns the server to the state it was in before the power
was removed.
■
disabled – (Default) Keeps the server off when power is applied.
If you enable HOST_LAST_POWER_STATE, you should also configure /SP/policy
HOST_POWER_ON_DELAY. See “Disable or Reenable the Host Power-On Delay” on page 59.
