2.3 How to Initiate a Reconfiguration Boot

2.3.1 Before You Begin

After installing any internal or external storage device, or any new part that plugs into the main logic board, except CPU modules or DIMMs, you must perform a reconfiguration boot so that your system is able to recognize the newly installed option(s).

A terminal or a graphics console is required for viewing system messages. For information about connecting a terminal or a console, see "2.10 About Communicating With the Server" or your Sun Enterprise 220R Server Owner's Guide.

Caution - Caution -

Before you power on the system, make sure that the system cover is properly installed and that the and doors are closed.

2.3.2 What to Do

  1. Turn on power to any peripherals and external storage devices.

    Read the documentation supplied with the device for specific instructions.

  2. Turn on power to the monitor or terminal.

  3. Turn the front panel keyswitch to the Power-On/Off position.

    See "2.9 About the Status and Control Panel".

    To run OpenBootTM Diagnostics(OBDiag) tests to verify that the system functions correctly with the new part(s) you have just installed, see "7.5 About OpenBoot Diagnostics (OBDiag)".

  4. When the system banner is displayed on the terminal or console, immediately enter the Stop-a sequence on the Sun keyboard or press the Break key on the terminal keyboard.

    The system banner contains the Ethernet address and host ID. To enter the Stop-a sequence, hold down the Stop key and press the a key.

    Note -

    The system may take anywhere from 30 seconds to two minutes before the system banner appears. This time depends on the level of power-on self-test (POST) diagnostics being performed.

  5. When the ok prompt is displayed, enter the following command: 


    ok boot -r

    This command rebuilds the device trees for the system, incorporating any newly installed options. After a device has been added to a device tree, it can be recognized by the system. After the reconfiguration reboot has successfully completed, the system prompt will be displayed.

    Caution - Caution -

    Never move the system when system power is on. Movement can cause catastrophic disk drive failure. Always power off the system before moving it.

2.3.3 What Next

The system's front panel LED indicators provide power-on status information. For information about the system LEDs, see:
