Procedure

If a message accompanied the failure, append the message identifier to the prefix MSG according to the procedures starting on Message keyword and add this keyword to the keyword string. If the system did not issue a message, try to identify any failure-related control blocks, user areas, or data records and record them on the Keyword worksheet as modifier keywords.
Specify the incorrect output keyword as INCORROUT.
If the system indicates damage to the VTOC or VTOC index, then DADSM or CVAF normally issues an error message. In this case, examine the Standard modifier keyword list and go to the DADSM/CVAF-related Incorrect output failure modifier keywords procedure to identify applicable symptom keywords. If VTOC problems are not indicated, continue with this procedure.
Accumulate as much of the following information as possible. It can help you isolate or resolve your problem, and the IBM® Support Center will request it if trap or trace information is needed.
- When was the problem first noticed?
- How was the problem identified (good output versus bad output)?
- Were any system changes or maintenance recently applied? For example, a new device, software product, APAR, or PTF?
- Does the problem occur with a specific data set, device, time of day, and so forth?
- Does the problem occur in batch or in TSO mode?
- Is the problem solid or intermittent?
- Can the problem be re-created?
