Troubleshooting the data migration

This information contains information related to specific data migration problems and how to resolve them.

Error messages and reference codes (also known as system reference codes or SRCs) let you know that an error occurred during the process.

Table 1. Data migration problems and resolutions
Description Resolution
Reference code A900 2000 appears on the control panel display. This reference code appears if the QIPLTYPE is set to 2 or if the console display has no device description. This reference code and message are normal during the data migration procedure. The reference code disappears when you perform a normal IPL. If no workstation on your system is operational when you receive reference code A900 2000, call your authorized service provider.
You see Message ID CPF3717: File not selected. File label or file name mismatch for file filename. This type of message occurs most frequently when the incorrect tape is inserted into the tape drive or when you have incorrect parameters for the RESTORE command.
Start of changeJob scheduler entries are not restored on the target system when you migrate from a system that does not support IBM® i 7.1End of change You must manually re-create the job scheduler entries on the target system. If you did not print these entries before you migrated your data, you can obtain them from the source system.
The target system cannot read the tapes you used to save the data from your source system. Save the data from the source system using a tape drive that is compatible with the target system.
You cannot configure your twinaxial devices. If you are using a twinaxial console on the source system and using Operations Console on the target system, you must have a twinaxial controller for any twinaxial devices you plan to run from the target system.
