The volume table of contents (VTOC) cannot be read because of an I/O error.
The data set is not scratched.
If the error recurs and the program is not in error, look at the messages in the job log for more information. Search problem reporting data bases for a fix for the problem. If no fix exists, contact the IBM® Support Center. Provide the JCL and the SYSOUT output for the job.
Request that the volume be restored.
