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
1. 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.
2. Reboot.
The newly activated boot environment is now the default on the x86 GRUB menu or SPARC boot
menu.

Note 2: The Basic Audit Reporting Tool (BART) feature of Oracle Solaris enables you to comprehensively validate systems by performing file-level checks of a system over time. By creating BART manifests, you can easily and reliably gather information about the components of the software stack that is installed on deployed systems.
BART is a useful tool for integrity management on one system or on a network of systems.
