Use the /SP/policy HOST_AUTO_POWER_ON property to power on the host when external power is applied to the server. If this policy is set to enabled, the SP sets HOST_LAST_POWER_STATE to disabled, if enabled.
You must have the admin role (a) to complete this task.
-> set /SP/policy HOST_AUTO_POWER_ON=value
where value can be:
enabled – When power is applied, automatically powers on the host when the SP has been booted.
disabled – (Default) Keeps the host power off when power is applied if HOST_AUTO_POWER_ON is set to disabled.
