Starting in Oracle Solaris 11.1, x86 based systems are installed with GRUB2. The menu.lst file is replaced by the /rpool/boot/grub/grub.cfg file. Do not edit this file manually. Instead, use the bootadm sub commands to add, change, and remove menu entries.
For more information about modifying the GRUB menu items, see Booting and Shutting Down Oracle Solaris 11.3 Systems.
When booting from a ZFS root file system on a GRUB2 system, the root device is specified as follows:
# bootadm list-menu the location of the boot loader configuration files is: /rpool/boot/grub default 0 console text timeout 30 0 release-version
The fast reboot feature provides the ability to reboot within seconds on x86 based systems. With the fast reboot feature, you can reboot to a new kernel without experiencing the long delays that can be imposed by the BIOS and boot loader.
You must still use the init 6 command when transitioning between BEs with the beadm activate command. For other system operations, use the reboot command as appropriate.
