If a MUPIP LOAD error occurs, ensure that the proper media is loaded and that the command input includes the proper file-specification.
If the input file is FORMAT=GO or ZWR, the database should contain the correct content to the point where the failure occurred and should be usable. You can edit and possibly correct the input file.
If the input file is FORMAT=BIN, the database is probably corrupt. Fix the database intergrity issues and EXTRACT the file again.
For more information on LOAD and EXTRACT, refer to the MUPIP chapter in the Administration and Operations Guide.
