This section contains information about power modes, server shutdown and reset options, and power off and reset procedures.
Determine how you will shut down power from the following methods:
Whenever possible, shut down the server gracefully using the server OS shutdown procedure.
You can power off the server module locally or remotely.
To power off locally, use the front panel power button.
To power off remotely, use the server OS shutdown procedure or Oracle ILOM.
You can perform either a graceful or an immediate shutdown of the server.
If possible, shut down the server gracefully using the server OS shutdown procedure or Oracle ILOM.
An immediate shutdown should be used in emergency situations or when you know that the loss of data is nonexistent or minimal.
Power descriptions follow.
Full power is the normal operational state for the server. When the server enters full power, power is supplied to all the server components, the server boots, and the operating system (OS) functions. You achieve full power by pressing the Power button on the server front panel when the server is in standby power. You can also achieve full power by powering on the server from Oracle ILOM. Once the server is operating in full power, the Power OK indicator is on continuously (does not blink).
Standby power is a non-operating state (OS does not boot), in which low-level power is supplied only to the components that are required to run the service processor (SP) and Oracle ILOM. To enter standby power, install the server into a fully-powered chassis, but do not press the front panel Power button. You can also enter standby power by powering off the server (from full power) using one of the power-off methods described in, Powering Down the Server Module. When entering standby power mode, the server front panel Power indicator blinks quickly while the SP is booting. When the SP has booted, the indicator blinks slowly to show that the server is in standby power mode.
A graceful shutdown (also referred to as an orderly shutdown) is the safest method of shutting down the server to standby power mode because it warns users, closes files, and prepares the file system. To perform a graceful shutdown, use the server OS shutdown procedure or the Oracle ILOM graceful power off option.
An immediate shutdown of the server (also referred to as an emergency shutdown) should be used only in situations when you know that the loss of data is nonexistent or acceptable. An immediate shutdown does not warn users, does not close files, nor does it prepare the file system for shut down to standby power mode.
Shutting down the server from full power mode to standby power mode does not completely remove power from the server. When it is in standby power mode, the server is in a low-power state. This low-power state is enough to maintain the service processor (SP), which runs Oracle ILOM. To completely remove power from the server module, you must disengage its internal connector from the chassis mid-plane by performing a full or partial removal. To perform a cold reset (see following section) of the server, completely remove power, wait 30-60 seconds, and install the server back into the chassis.
A warm reset of the server is a reboot or restart of the server. It involves cycling the server power from full power mode to standby power mode and back to full power mode. For example, a warm reset might be required after a software or firmware update or when you want to launch Oracle System Assistant or access the BIOS Setup Utility.
A cold reset of the server is a restart of the server from a completely powered-off state. A cold reset might be required to resolve a system issue. To perform a cold reset, place the server module in standby power mode, disconnect the server from its power source by performing a complete power removal (see above), wait 30-60 seconds, and then connect the server to its power source.
