Dynamic Reconfiguration Operations and Resource Pools

Dynamic reconfiguration (DR) enables you to reconfigure hardware while the system is running. Because DR affects available resource amounts, the pools facility must be included in these operations. When a DR operation is initiated, the pools framework acts to validate the configuration.

If the DR operation can proceed without causing the current pools configuration to become invalid, then the private configuration file is updated. An invalid configuration is one that cannot be supported by the available resources.

If the DR operation would cause the pools configuration to be invalid, then the operation fails and you are notified by a message to the message log. If you want to force the configuration to complete the process, you must use the DR force option. The pools configuration is then modified to comply with the new resource configuration.
