Use the ^ and v keys to select which entry is highlighted.
Press enter to boot the selected OS, 'e' to edit the
commands before booting, or 'c' for a command-line.
After the rollback boot menu entry is selected, the system boots the old kernel software,
but the rollback must be manually confirmed on the console to commit the rollback, which
effectively removes all changes to the system that have happened since, as described above. The
confirmation step looks like this:
SunOS Release 5.11 Version ak/generic@2011.04.24.4.2,1-1.28 64-bit
Copyright (c) 1983, 2010, Oracle and/or its affiliates. All rights reserved.
System rollback in progress.
Rollback to: ak/nas@2011.04.24.4.2,1-1.28
Proceed with system rollback [y,n,?]
When prompted to proceed with system rollback, enter one of the following:
2.
Enter "y" to proceed with the rollback.
a.
The system reboots using the prior snapshot.
Enter "n" to cancel the rollback and immediately reboot the system.
b.
This action allows the administrator to select the current software version or an older
snapshot boot image.
Rolling Back the System Software (BUI)
Use the following procedure to roll back the system software using the BUI.
To roll back, locate a previous image and click on the rollback icon
are asked to confirm that you wish to execute a rollback, and then the system
reboots and executes the rollback. Unlike fail-safe rollback, you are not asked
for further confirmation when the system reboots. For information on the fail-
safe rollback, see
