Repeating (copying) processors

You can copy processors within the same or to another IODF. When copying a processor, the following related objects and connections are also copied:
  • Channel subsystems (for XMP processors only)
  • Partitions
  • Channel paths
  • PCIe functions
  • Control units
  • Devices

When you copy a processor within the same IODF, you create a new processor. When you copy a processor into a different IODF, you can either create a new processor with the Repeat (copy) processor configuration action, or, with the same action, merge the configuration of the source processor into an existing configuration of the target processor.

Before copying the processor to an existing processor in another IODF (merge the processor configurations), check the following:

  1. Make sure that source and target processor have the same type-model and support level.
  2. Check the partition usage type if the processor has several partitions.
    You cannot replace a partition that has a different usage type (except if there are no channel paths defined for this partition):
    Usage Type in Source IODF Matching Usage Type in Target IODF
    OS → OS
    CF → CF
    CF/OS → CF, OS, or CF/OS

    If the partition usage types do not match, change them in the target IODF.

  3. If a channel path already exists in the target IODF, make sure that it has the same type.
  4. If the target channel path connects to another dynamic switch than the source channel path, disconnect the channel in the target IODF.
  5. To replace a shared channel path mode by a dedicated or reconfigurable channel path mode, change the mode or delete the incompatible channel path in the target IODF.
  6. If a processor is copied that has a local system name defined, but the CPC name is changed for the copied processor, the local system name is left unchanged. Whenever a local system name has been defined, either explicitly or by default, a change only happens by explicit user action.

Copy a processor as follows:

  1. Copy the processor using the Repeat (copy) processor configurations action from the context menu (or action code  r ) on the Processor List. The Identify Target IODF panel is displayed.
  2. Specify the IODF to which the selected processor configuration is to be copied. The default IODF is the IODF you are currently working with.
  3. On the following Repeat Processor panel, specify the required values and press the Enter key.

    Definitions for source partitions are merged with the definitions of the target partitions. If a target partition has another partition number than the source partition, HCD keeps the target partition number.

    If control units, devices, CHPIDs, or PCIe functions already exist in the target IODF (same number and type), HCD tries to map them. Migrating additional IOCP input data sets explains in detail when a device or control unit is mapped. The general rule is, that target definitions are updated from the source definitions.
