6.2.1 Flow From System Stop to Input Power-off
This section describes the flow from stopping the system to turning off the input power.

To stop the system, all the logical domains in the target physical partition must be shut down. The shutdown of the logical domains has a specific order: the domains other than the control domain are shut down first, and then the control domain must be shut down.
The SPARC M12/M10 systems support a technique called ordered shutdown, which shuts down logical domains in an appropriate order and then stops the physical partition, so users do not need to pay attention to the shutdown of logical domains.
For an ordered shutdown, numbers representing the order in the group to be shut down are defined for the logical domains in advance. The XSCF stores the defined order to enable shutdown in an appropriate order with this technique, even under XSCF management.
If a non-active guest domain is included in the group for which an ordered shutdown is defined, it takes about 10 minutes to shut down the group.
For details on an ordered shutdown, see "8.7 Ordered Shutdown of Logical Domains."
