Repeating (copying) channel subsystems

You can copy channel subsystems within the same or to another IODF:

1. merge the source CSS with an existing target CSS in the same processor
2. copy a source CSS to a new target CSS in the same processor
3. copy a source CSS to another XMP processor

Copy or repeat a channel subsystem as follows:

• On the Processor List, select an XMP processor and the action Work with channel subsystems . . (XMP) from the context menu (or action code  s ).
• On the Channel Subsystem List, for the source CSS, select action Repeat (Copy) channel subsystem from the context menu (or action code  r ).
• Specify the IODF to which the selected operating system is to be copied. The default IODF is the IODF you are currently working with.
• On the following panel, specify your target processor and CSS ID:

  ┌──────────────────── Repeat Channel Subsystem ────────────────────┐
  │                                                                  │
  │                                                                  │
  │ Specify or revise the following values.                          │
  │                                                                  │
  │ Processor ID . . . . . . PROC4     +                             │
  │ Channel subsystem ID . . 2  +                                    │
  │                                                                  │
  └──────────────────────────────────────────────────────────────────┘

• Depending on what you want to do, continue as follows:
  • To merge source and target CSS, you are prompted for confirmation for merging the source CSS data into the target CSS data. If you confirm, you are prompted to specify new partition names, because the partitions within an XMP processor must be unique:

                      Specify New Partition Names
                                                       Row 1 of 2
      Command ===> ____________________________________________
    
      The partitions listed have already been defined in the
      target processor. Specify new names and press ENTER.
    
      Partition  New Name
      LPAR01     ________
      LPAR02     ________
      ********************* Bottom of data **********************

    A message indicates the successful processing.

  • To copy the source CSS into a new target CSS, you can specify or revise certain characteristics of the target CSS:

    You are prompted to specify new partition names. Also, a message indicates the successful processing.

  • To copy a source CSS to another XMP processor, the processing is identical as copying into a new target CSS. However, specifying new partition names is only necessary if the partition names of the source processor already exist in the target processor.
