The /SP/policy PARALLEL_BOOT property, when enabled, allows the host to boot and power on in parallel with the SP if an auto-power policy (HOST_AUTO_POWER_ON or HOST_LAST_POWER_STATE) was on or a user presses the power button while the SP is in the process of booting. ILOM has to be running in order to enable the host to power on when the power button is pressed or the auto-power policies are set. When this property is set to disabled, the SP boots first, then the host boots.
-> set /SP/policy PARALLEL_BOOT=value
where value can be:
enabled – SP and host boot concurrently.
disabled – SP and host boot serially.
