The server can be in one of these states:
No power applied – No power is applied to the server. For example, when the power cords are not connected, or the datacenter power breaker is off.
Standby – Power is applied to the server, the SP is running, but main power is not applied to the host. You can access Oracle ILOM on the SP in Standby state.
Fully powered on – The host is powered on and you can access Oracle ILOM. Once the server boots the OS, you can also access Oracle ILOM and the operating systems running on the PDomains.
