When you modify server complex properties, the Server Complexes
task runs an automatic consistency check. This check alerts you to any changes
that may have been applied manually, or by another tool, or by another administrator.
This automatic check occurs after you make changes to the properties
of a server complex and click
OK, or after you move a Linux guest system
to, or from, a server complex. Before the reconfiguration is applied, the
new configuration is checked against the old properties. If there is an inconsistency,
the Progress Indication window displays a report of the differences between
the old property values and the actual state, and offers a choice to stop
or to proceed.
註: This consistency check does not occur when you click
the Apply button in the Server Complex Properties window.
