Memory Reconfiguration of the Control Domain

You can use the memory DR feature to reconfigure the memory of the control domain. If a memory DR request cannot be performed on the control domain, you must first initiate a delayed reconfiguration.

Using memory DR might not be appropriate for removing large amounts of memory from an active domain because memory DR operations might be long running. In particular, during the initial configuration of the system, you should use delayed reconfiguration to decrease the memory in the control domain.
