How to Automatically Configure a SCSI Drive

1. Become superuser.

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

   # touch /reconfigure

3. Shut down the system.

   # shutdown -i0 -g30 -y

   -i0	Brings the system down to init state 0 (zero), the power-down state.
   -g30	Notifies logged-in users that they have n seconds before the system begins to shut down.
   -y	Specifies the command should run without user intervention.

   The ok or > prompt is displayed after the operating environment is shut down.

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

5. Make sure 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 will boot and display the login prompt.

9. Login as superuser, invoke the format utility, and select the disk to be configured automatically.

10. Reply yes to the prompt to label the disk.

    Replying y will cause the disk label to be generated and written to the disk by the autoconfiguration feature.
