Solaris 10 8/07 Installation Guide: Solaris Live Upgrade and Upgrade Planning

Procedurex86: To Activate a Boot Environment With the GRUB Menu

You can switch between two boot environments with the GRUB menu. Note the following limitations:

  1. Become superuser or assume an equivalent role.

    Roles contain authorizations and privileged commands. For more information about roles, see Configuring RBAC (Task Map) in System Administration Guide: Security Services.

  2. Reboot the system.

    # init 6

    The GRUB main menu is displayed. The two operating systems are listed, Solaris and second_disk, which is a Solaris Live Upgrade boot environment. The failsafe entries are for recovery, if for some reason the primary OS does not boot.

    GNU GRUB version 0.95 (616K lower / 4127168K upper memory)

    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.
  3. To activate a boot environment, use the arrow key to select the desired boot environment and press Return.

    The selected boot environment is booted and becomes the active boot environment.
