When the Oracle Solaris OS is first installed on SuperCluster M8 and SuperCluster M7, a boot environment is created. You can use the beadm(1M) utility to create and administer additional boot environments on your SuperCluster system.
After your SuperCluster system is installed, create a backup of the original boot environment. If needed, you can then boot to the backup of the original boot environment.
