FUNL0027 Truncated file - (ddname).

A physical file making up a logical database file does not have enough space allocated to hold the pages that are indicated by the FPL data set list. This could be caused by inadvertent truncation of a physical file by a utility program such as IEBGENER or DUMP/RESTORE. This could also be caused by an invalid DD card or FILEDEF. Verify the correctness of your DD card or FILEDEF and, if correct, try to recover the file from a backup.
