To Activate a Boot Environment and Synchronize Files (Command-Line Interface)

The first time you boot from a newly created boot environment, Solaris Live Upgrade software synchronizes the new boot environment with the boot environment that was last active. “Synchronize” means that certain critical system files and directories are copied from the last-active boot environment to the boot environment being booted. Solaris Live Upgrade does not perform this synchronization after the initial boot, unless you force synchronization with the luactivate command and the -s option.

For more information on synchronization, see Sychronizing Files Between Boot Environments.

1. Log in as superuser.

2. To activate the boot environment, type:

   # /usr/sbin/luactivate -s BE_name

   -s

   Forces a synchronization of files between the last-active boot environment and the new boot environment. The first time that a boot environment is activated, the files between the boot environment are synchronized With subsequent activations, the files are not synchronized unless you use the -s option.

   Caution –

   Use this option with great care, because you might not be aware or in control of changes that might have occurred in the last-active boot environment. For example, if you were running Solaris 9 software on your current boot environment and booted back to a Solaris 2.6 release with a forced synchronization, files could be changed on the 2.6 release. Because files are dependent on the release of the operating environment, the boot to the Solaris 2.6 release could fail because the Solaris 9 files might not be compatible with the Solaris 2.6 files.

   BE_name

   Specifies the name of the boot environment that is to be activated.

3. Reboot.

   # init 6

Example 33–11 Activating a Boot Environment (Command-Line Interface)

In this example, the second_disk boot environment is activated at the next reboot and the files are synchronized.

# /usr/sbin/luactivate -s second_disk
# init 6
