Definitions for "Reinstallation"
An installation, automatically initiated by Change Manager, that overwrites the system's disk or disks with the new version of the Solaris operating environment. You can perform a reinstallation if the system is already running the Solaris operating environment that contains the Sun Management Center agent and the Change Manager agent module. The reinstallation operation requires only one boot environment. You might perform a reinstallation when you cannot use Solaris Live Upgrade, for example, when the root slice is mirrored.
a case where a user runs the installer to install some features, then runs the installer at some later time to install more features
An installation of a Solaris Flash archive on a managed host. Unlike an initial installation, reinstallation is initiated by the Change Manager. Therefore, you do not need to initiate the installation manually from the managed host's console. The reinstallation operation requires only one boot environment. The reinstallation operation is useful for disk volume managers because they are not compatible with the Solaris Live Upgrade feature.
