1.5.2 Using Physical Partition Dynamic Reconfiguration
The physical partition dynamic reconfiguration function (PPAR DR function) is used as follows:
  1. Increasing hardware resources
    In response to business expansion and system load increases, you can add a system board (PSB<BB>) to a physical partition without stopping any task on the physical partition. If necessary, additional CPU Activations must be procured and configured.
  2. Reducing hardware resources
    To efficiently use hardware resources according to changes in the size of your business, you can delete a PSB (BB) from a physical partition without interrupting the ongoing business.
  3. Moving hardware resources
    To handle temporary business expansion and load increases, you can temporarily delete the PSB (BB) from another physical partition. The deleted PSB (BB) can then be added to a physical partition that requires an increase in hardware resources. This enables hardware resources to be moved while tasks on the two physical partitions are running. The system can be configured to flexibly respond to variations in the system load.
  4. Active replacement at part failure
    If the hardware resources on a PSB (BB) are degraded as a result of a failure of the PSB (BB), you can temporarily delete that PSB (BB) from the physical partition and replace the failed parts without stopping any task on the physical partition. After the parts are replaced, you can then restore the original configuration by adding the PSB (BB) to the physical partition without stopping any task.
