Step 4: Update configuration data

If the protocol or the attached devices specified in the IOCP input data set do not match the supported control unit model, HCD may change the model definitions.

If HCD changes definitions, you are informed by messages. Review the messages, and follow the recommendation provided in the individual message.

If the type/model designated by HCD does not match the real type/model of the control unit, use the HCD dialog to specify the correct type/model.

Also, if this control unit is to be shared with another processor, update the IOCP input data set that is to be migrated accordingly.

Note:

The configuration stored in an IODF may not match the IOCP/MVSCP or HCPRIO input. If discrepancies occur, you can make corrections by using the dialog.

The following note only applies if you do not use the extended migration function as described in Changing I/O configurations by editing data sets.

For coupling facility migration:

After the IOCP input has been accepted, HCD issues messages informing you that the CF control unit and CF device definitions of the IOCP input data set were ignored.
