Reach a State to Install a Fresh OS (Oracle ILOM CLI)

If you do not plan to use the preinstalled OS, use this procedure to prevent the server from booting from the preinstalled OS.

  1. Prepare the appropriate boot media according to your installation method.

    There are many methods by which you can install the OS. For example, you can boot and install the OS from external media or from another server on the network.

    For more information about the methods, refer to: Installing Oracle Solaris 11 Systems, comparing installation options at:http://www.oracle.com/goto/solaris11/docs

  2. From Oracle ILOM, set the OpenBoot auto-boot? parameter to false.
    -> set /HOST/bootmode script="setenv auto-boot? false"

    This setting prevents the server from booting from the preinstalled OS. When you use bootmode, the change applies only to a single boot and expires in 10 minutes if the power on the host is not reset.

  3. When you are ready to initiate the OS installation, reset the host.
    -> reset /System
    Are you sure you want to reset /System (y/n)? y
    Performing reset on /System
  4. Switch communication to the server host.
    -> start /HOST/console
    Are you sure you want to start /HOST/console (y/n)? y
    Serial console started. To stop, type #.

    The server might take several minutes to complete POST, and then the OpenBoot prompt (ok) is displayed.

  5. Boot from the appropriate boot media for your installation method.

    For more information, refer to: Installing Oracle Solaris 11 Systems, comparing installation options at:http://www.oracle.com/goto/solaris11/docs

    For a list of valid boot commands that you can enter at the OpenBoot prompt, type:

    {0} ok help boot
    boot <specifier>  ( -- )    boot kernel ( default ) or other file
      Examples:
        boot                    - boot kernel from default device.
                                   Factory default is to boot
                                   from DISK if present, otherwise from NET.
        boot net                - boot kernel from network
        boot cdrom              - boot kernel from CD-ROM
        boot disk1:h            - boot from disk1 partition h

      Examples:
         4000 dload /export/root/foo/test

                      or if Forth program, compile it
