Solaris 10 10/08 Installation Guide: Custom JumpStart and Advanced Installations

x86: Performing a Custom JumpStart Installation by Editing the GRUB Boot Command

In some circumstances such as for debugging purposes, you might want to modify the GRUB boot command. The following procedure describes the steps to edit the GRUB boot command before performing the custom JumpStart installation.

Procedurex86: To Modify the GRUB Boot Command

  1. To begin the installation, proceed with Step 1 through Step 5 in the preceding procedure, x86: To Perform an Installation or Upgrade With the Custom JumpStart Program and With GRUB.

  2. If the system is off, turn the system on. If the system is on, reboot the system.

    The GRUB menu is displayed. This menu provides a list of boot entries. The entry that is provided is the Solaris instance to be installed.

    GNU GRUB version 0.95 (631K lower / 2095488K upper memory)
    |Solaris 10 10/08 image_directory                                      |
    |Solaris Serial Console ttya                                                |
    |Solaris Serial Console ttyb (lx50, v60x and v68)                  |
    Use the ^ and v keys to select which entry is highlighted. Press
    enter to boot the selected OS, 'e' to edit the commands before
    booting, or 'c' for a command-line.

    The image_directory is the name of the directory where the installation image is located.

    Note –
    • If you used the NFS to set the path to the JumpStart directory with the add_install_client command and the -c option, then you do not need to include the path in the boot entry.

    • If you are not using NFS, then you must note the path to the compressed configuration file that contains the JumpStart directory.

  3. To stop the booting process and use the menu entry editor, type e.

    The GRUB edit menu is displayed.

    kernel /I86PC.Solaris_11-8/multiboot kernel/unix -B console=ttyb,\
    install_media= \
    module /I86PC.Solaris_11-8/
  4. Use the arrow keys to select the boot entry.

  5. To edit the selected command, type e.

    A command that is similar to the following example displays.

    grub edit>kernel /I86PC.Solaris_11-8/multiboot kernel/unix -B \
    module /I86PC.Solaris_11-8/
  6. Edit the command by typing the options that you need.

    The syntax for a JumpStart installation is the following.

    grub edit>kernel /I86PC.Solaris_11-image_directory/multiboot kernel/unix/ \
    - install [url|ask] options -B install_media=media_type

    For a description of JumpStart options, see x86: Command Reference for Booting the System.

    In the following example, the OS is installed over the network with a custom JumpStart profile.

    kernel /I86PC.Solaris_11-8/multiboot kernel/unix/ - install \
    -B install_media= \
    module /I86PC.Solaris_11-8/
  7. To accept the edits, press Enter.

    Your changes are saved and the GRUB main menu is displayed.

    Note –

    Pressing the Escape key returns you to the GRUB main menu without saving your changes.

  8. To begin the installation, type b.
