Copying a channel subsystem

HCM offers the Copy Channel Subsystem wizard that supports you to copy a channel subsystem:

• copy a channel subsystem into the same or another existing XMP processor
• copy a channel subsystem into a new SMP processor

Invoke this wizard by pressing the Copy… button in the Channel Subsystems section of the Processor dialog for XMP processors (Figure 2).

The wizard guides you through the following steps.

1. Choose the target channel subsystem or SMP processor.
   1. If you have chosen to copy the channel subsystem into a new SMP processor, the wizard offers a dialog which is similar to the Create Processor dialog. Then it proceeds to step 4.
   2. If you have chosen to copy the channel subsystem into a new target channel subsystem, specify the attributes of the target CSS. The wizard continues with step 2.
2. Assign partition names in the target CSS for all partitions which are copied from the source CSS. The partition names of the source CSS are used as the default for the target CSS, if these names will be unique also within the target XMP processor . For duplicate names, you need to specify new names for the target CSS.
3. Map CHPIDs of the source CSS to CHPIDs in the target. CHPIDs that can be defined as 'spanned', can be spanned over existing CHPIDs in other channel subsystems of the target processor.
4. Choose how you want to handle the connections:
   • If you want to copy the logical connections without moving the physical connections, choose the Repeat scenario.
   • If you want to copy the logical connections and move the physical ones from the source to the target, choose the Upgrade scenario.
   Note: For a better understanding of the Repeat and Upgrade scenarios and the wizard 's panel flow depending from your selection, refer to General concepts of the copy wizards.
5. If you select the Upgrade scenario, the physical connections of the CHPIDs on the source CSS are moved to the target CHPIDs, if possible.

   If you selected the Repeat scenario, then the wizard helps you to perform the following steps:

   1. Assign switch port connections for all target CHPIDs whose corresponding source CHPIDs have a switch port connection. Target CHPIDs with existing switch port connections are not shown in this step.
   2. Assign controller interface connections for all target CHPIDs whose corresponding source CHPIDs are physically connected to a controller. Target CHPIDs with existing physical connections are not shown in this step.
6. View the messages at the summary page, verify the results and click the Finish button.

The wizard displays appropriate dialogs as you proceed through these steps. For further information about how to complete these dialogs, refer to the online help that is available for each wizard page. Also refer to How HCM handles connections when using the copy wizards.
