If you experience a failure while booting the new boot environment and can boot the original boot environment in single-user mode, use this procedure to fall back to the original boot environment.
If you need to boot from media or a net installation image, see SPARC: To Fall Back to the Original Boot Environment by Using a DVD, CD, or Net Installation Image.
At the OK prompt, boot the machine to single-user state from the Solaris Operating System DVD, Solaris Software - 1 CD, the network, or a local disk.
OK boot device_name -s
Specifies the name of devices from where the system can boot, for example /dev/dsk/c0t0d0s0
# /sbin/luactivate BE_name
Specifies the name of the boot environment to be activated
If this command fails to display a prompt, proceed to SPARC: To Fall Back to the Original Boot Environment by Using a DVD, CD, or Net Installation Image.
If the prompt is displayed, continue.
At the prompt, type:
Do you want to fallback to activate boot environment <disk name> (yes or no)? yes
A message displays that the fallback activation is successful.
# init 6
The previous working boot environment becomes the active boot environment.
