Invoking the Configuration Manager

During system boot time, the Configuration Manager is run in two phases. In phase 1, it configures the base devices needed to successfully start the system. These devices include the root volume group, which permits the configuration database to be read in from the root file system.

In phase 2, the Configuration Manager configures the remaining devices using the configuration database from the root file system. During this phase, different rules are used, depending on whether the system was booted in normal mode or in service mode. If the system is booted in service mode, the rules for service mode are used. Otherwise, the phase 2 rules are used.

The Configuration Manager can also be invoked during run time to configure all the detectable devices that might have been turned off at system boot or added after the system boot. In this case, the Configuration Manager uses the phase 2 rules.
