Automatic mapping and processing intersections

The IBM Z Connectivity Tool provides two methods for mapping logical configuration, such as CHPIDs and FIDs, to the physical features; automatic mapping and manual mapping.

Automatic mapping
Automatically assigns CHPIDs and FIDs to features for maximum availability
Manual mapping
Manually assigns CHPIDs and FIDs to features.

To get the maximum benefit from the IBM Z Connectivity Mapping Tool, it is recommended to use automatic mapping whenever possible. However, certain situations may require manual mapping before performing automatic mapping.

Manual mapping may also be recommended in the following circumstances:
  • When there are specific requirements about how CHPIDs should be arranged on the machine
  • To make minor mapping adjustments
  • To eliminate intersections.

For details about performing manual mapping, see Manual mapping.
