Changing the Default Boot Environment
You can change an inactive boot environment into an active boot environment. Only
one boot environment can be active at a time. The newly activated
boot environment becomes the default environment upon reboot.
How to Activate an Existing Boot Environment
- Use the following command to activate an existing, inactive boot environment:
$ beadm activate beName
beName is a variable for the name of the boot environment to be
activated.
Note the following specifications.
beadm activate beName activates a boot environment by setting the bootable pool property, bootfs, to the value of the ROOT dataset of the boot environment that is being activated.
beadm activate sets the newly activated boot environment as the default in the menu.lst file.
Note - When a boot environment is created, whether it is active or inactive, an entry is created for the boot environment on the GRUB menu. The default boot environment is the last boot environment that was activated.
- Reboot.
The newly activated boot environment is now the default on the GRUB menu.
Note - If the boot environment fails to boot, reboot and select the previous boot
environment from the GRUB menu.
