Live Update

To perform a live update operation (also called update), the managed host must be running the Sun Management Center agent and the Change Manager agent module. The update uses the Solaris Live Upgrade feature to install the Solaris Flash archive on the inactive boot environment of a running managed host. When the installation completes, the inactive boot environment is marked as active and the system reboots to run the new software stack. The other boot environment is unchanged.

You can fall back to the previous boot environment to ``undo'' the update operation. This fallback operation marks the previously running boot environment as the active boot environment, then reboots the system to run the previous software stack.

You can monitor the setup for installation, update, and reinstallation operations by viewing the Change Manager job queue. See Chapter 7, Monitoring Jobs (Tasks).
