LABELDEF GENN number NOT EQUIVALENT TO CA VM:Tape CALCULATED GENERATION NUMBER number

Reason:

You tried to reference a generation data set with conflicting parameters. The FILEDEF SYSPARM option GDG (generation data group) is used to calculate the CA VM:Tape cataloged generation value. The calculated value disagrees with the GENN value specified on the CMS LABELDEF command. The mount request ends with return code 28.

Action:

Use the generation number calculated by CA VM:Tape and displayed in the message to replace the LABELDEF GENN value.
