Change the Default Boot Device (OpenBoot)

Use this procedure to configure OpenBoot to boot from a specific device. This change is permanent but only takes effect after a reset.

1. Obtain the ok prompt.

   See Obtaining the OpenBoot Prompt.

2. Determine the name of the desired boot device.

   To see names of devices, type:

   ok devalias
   

   You should see the names of storage and other devices including the boot device you want to use. See Matching Devices to Device Names for more information.

3. Configure the boot-device parameter with your desired boot device.

   ok setenv boot-device boot_device
   

   where boot_device is a valid device from which to boot, shown with the previous devalias command.

   For example, to boot from the device with the alias disk1:

   ok setenv boot-device disk1

4. Verify the change.

   ok printenv boot-device
   

5. Reset the host.

   ok reset-all
