# luactivate new-zfsBE
**********************************************************************

The target boot environment has been activated. It will be used when you 
reboot. NOTE: You MUST NOT USE the reboot, halt, or uadmin commands. You 
MUST USE either the init or the shutdown command when you reboot. If you 
do not use either init or shutdown, the system will not boot using the 
target BE.

**********************************************************************
In case of a failure while booting to the target BE, the following process 
needs to be followed to fallback to the currently working boot environment:

1. Enter the PROM monitor (ok prompt).

2. Change the boot device back to the original boot environment by typing:

     setenv boot-device /pci@1f,0/pci@1/scsi@4,1/disk@2,0:a

3. Boot to the original boot environment by typing:

     boot
