Usage
INITIAL POWER-ON
When first applying standby power to the
C1P9S01, i.e., when the system is plugged in after being
disconnected from power, the internal BMC needs to boot before any other operation request will be accepted.
The status of this BMC boot is indicated by two front panel LED patterns:
When these patterns have been replaced by normal front panel operation, the system is ready to accept
commands.
There are two primary methods of interacting with the OpenPOWER bootloader, serial and graphical. By
default, the rear serial port is an active serial console during the IPL process; it may be accessed either via a
terminal running at 115,200 baud or via the
obmc-console-client
application on the BMC. Alternatively, the
integrated VGA port and/or any discrete GPUs supported by the internal Linux kernel will allow interaction with
the bootloader.
With your choice of peripherals connected for bootloader menu access, press the power button on your chassis.
Within a few seconds the system should initiate the IPL cycle, and in about 10 seconds the front panel will start
showing IPL status information on the ID / NIC1 / NIC2 LEDs. This front panel status information will override
normal front panel indicators until IPL has completed, at which point the system will also emit one short beep to
indicate IPL completion.
SELECTING A BOOT MEDIUM
After IPL has completed, you will be presented with the Petitboot main menu. If this system has already been
configured with a supported operating system, a boot countdown will start. Pressing any key will abort this
countdown and allow interaction with the boot menu. Petitboot currently supports a wide variety of boot media,
from TFTP sources to NVMe storage and local SATA / SAS devices; any connected media with a compatible
boot structure will be automatically detected and added to the list of boot options.
