Procedurex86: To Activate a Boot Environment With the GRUB Menu (Command-Line Interface)

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

Steps
  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.
