x86: Initiating a Fast Reboot to an Alternate Boot Environment

You can optionally use the reboot command with the -f and -e options to specify an alternate BE.


# reboot -f -e alternate-be-name
Note –

The -e option has dependencies on Solaris Live upgrade packages, in particular the lumount and luumount commands. Because Solaris Live Upgrade is not supported in the OpenSolaris release, you cannot use this option to specify an alternate BE. Instead, use the -f option by itself to directly specifying the alternate dataset. See x86: Initiating a Fast Reboot to an Alternate Boot Environment in the OpenSolaris 2008.11 OS.

Example 12–16 x86: Using Fast Reboot to Reboot to an Alternate Boot Environment

This example shows how to fast reboot to an alternate BE by using the reboot command with the -f and the-e options. Note that in this example, the bootadm list-menu command is used to display a list of the bootable environments that are available on a system. A fast reboot of the s3 BE is then initiated.


# bootadm list-menu
