How to Automatically Configure a SCSI Drive

  1. Become superuser or equivalent role.

  2. Create the /reconfigure file that will be read when the system is booted.


    # touch /reconfigure
    
  3. Shut down the system.


    # shutdown -i0 -gn -y
    

    -in

    Brings the system down to init level 0, the power-down state. 

    -g30

    Notifies logged-in users that they have n seconds before the system begins to shut down.

    -y

    Specifies that the command should run without user intervention. 

    The ok prompt is displayed after the system is shut down.

  4. Turn off the power to the system and all external peripheral devices.

  5. Make sure that the disk you are adding has a different target number than the other devices on the system.

    You will often find a small switch located at the back of the disk for this purpose.

  6. Connect the disk to the system and check the physical connections.

    Refer to the disk's hardware installation guide for installation details.

  7. Turn on the power to all external peripherals.

  8. Turn on the power to the system.

    The system boots and displays the login prompt.

  9. Log back in as superuser or assume an equivalent role.

  10. Invoke the format utility and select the disk that you want to configure automatically.
