Find information on some of the problems that might occur when you perform a data migration.
This topic contains information related to specific data migration problems. In many cases, the time you spend planning and performing the data migration using the instructions in this topic collection can prevent the following problems from occurring.
- Reference code A900 2000 appears on the control panel display of the server.
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 server 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.
- Job scheduler entries are not restored on the target server when you migrate
from a model 4xx, 5xx, or 6xx.
You must manually re-create the job scheduler entries on the target server. If you did not print these entries before you migrated your data, you can obtain them from the source server.
- The target server cannot read the tapes that you used to save the data
from your source server.
Save the data from a source server by using a tape drive that is compatible with the target server.
- You cannot configure your twinaxial devices.
If you are using a twinaxial console on the source server and using Operations Console on the target server, you must have a twinaxial controller for any twinaxial devices you plan to run from the target server.

problems.
