Non-Scratch Tape Messages

If the operator mounts a tape for output and CA 1 determines the tape cannot be used as a scratch, the operator receives a console message stating it is not a scratch and specifies a reason code. Some possible reasons are the following:

• Nonresident tape was requested but CA 1 tape is mounted
• Wrong tape is mounted for NL, BLP-specific request
• Tape is CA 1 permanent hold
• Tape is marked out-of-area
• Possible duplicate volume serial number (TMC DSN and HDR1 DSN do not match)
• Tape has not been scratched
• Tape is part of a multi-volume data set
• Tape contains secondary files, and the output request is not for file n+1 (tape contains n files)
• Tape has been remounted as part of a multi-volume data set
• Tape is mounted from the wrong scratch pool

In most instances, the tape is demounted and another scratch request is issued. There are circumstances, however, when CA 1 abends the tape job for certain types of processing violations.
