Managing the cluster resources
Use these topics to manage the resources in your cluster. The first part describes the dynamic reconfiguration process. The second part describes procedures for making changes to individual cluster resources.
When you configure a PowerHA® SystemMirror® cluster, configuration data is stored in specific PowerHA SystemMirror object classes in the ODM. The AIX® ODM object classes are stored in the default system configuration directory (DCD), /etc/objrepos.
You can make certain changes to both the cluster topology
and to the cluster resources while the cluster is running (dynamic
reconfiguration, or DARE). You can make a combination of resource
and topology changes via one dynamic reconfiguration operation making
the whole operation faster, especially for complex configuration changes.
Note: No
automatic corrective actions take place during a DARE.
