SPARC: How to Change the Default Boot Device

  1. Become superuser.

  2. Change to run level 0.


    # init 0

    The ok PROM prompt is displayed.

    For more information, see init(1M).

  3. Change the value of the boot-device parameter.


    ok setenv boot-device device[n]

    boot-device

    Identifies the parameter for setting the device from which to boot. 

    device[n]

    Identifies the boot-device value such as a disk or the network. The n can be specified as the disk number.

    Use the probe-scsi-all command if you need help with identifying the disk number.

  4. Verify that the default boot device is changed.


    ok printenv boot-device

  5. Save the new boot-device value.


    ok reset

    The new boot-device value is written to the PROM.
