**********************************************************************

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. Boot from the Solaris failsafe or boot in Single User mode from Solaris 
Install CD or Network.

2. Mount the Parent boot environment root slice to some directory (like 
/mnt). You can use the following commands in sequence to mount the BE:

     zpool import rpool
     zfs inherit -r mountpoint rpool/ROOT/my20111004upd
     zfs set mountpoint=<mountpointName> rpool/ROOT/my20111004upd 
     zfs mount rpool/ROOT/my20111004upd

3. Run <luactivate> utility with out any arguments from the Parent boot 
environment root slice, as shown below:

     <mountpointName>/sbin/luactivate

4. luactivate, activates the previous working boot environment and 
indicates the result.

5. Exit Single User mode and reboot the machine.
