You can use the BADFILE (Bad File) command in response to certain “MT <unit number> RECOPY REQUIRED <file name> RSVP” messages.
Syntax

Explanation
When an error occurs on tape while library maintenance is copying from tape, you can use this response to direct library maintenance to continue copying the file to disk even though the resulting file will contain some corrupted data. Library maintenance changes the names of the output disk files so that the node BADFILE is attached to the beginning of the file name. Library maintenance also stores a summary of the errors that occurred in the BADINFO disk file header attribute. For output tape files, library maintenance treats the BADFILE response like an OF (Optional File) response that is, it does not copy the corrupted file to tape.
Example
