The tape subsystem exception report series shows error data and usage statistics for tape subsystems. Data is summarized by component.
The series comprises any combination of the following tape reports:
| Tape reports | |
|---|---|
| Subsystem exception | Permanent/recovered error summary |
| Permanent error summary | Error code summary report |
| Temporary error summary | Temporary error summary device |
| Forced error log | Temporary error summary channel |
| DEVNO⁄CUA statistics summary | Library permanent/recover report |
| Volume statistics summary | Library error code summary report |
| FRU summary | CUA statistics summary |
Refer to your device maintenance information (MI) manual for the list of EREP reports that appear under the subsystem exception report for your specific device.
The reports are organized as shown in the following table:
| ORGANIZED BY | DESCRIPTION |
|---|---|
| Exception type | Permanent errors and temporary errors that exceed the values in the LIMIT control statement |
| Suspected source of the error | Either hardware or the volume and the drive it has been created on. |
The following table shows the type of error records and their source in the tape subsystem exception reports.
| TYPE | SOURCE |
|---|---|
| A3 | Tape devices (not 3590s) ; including controllers |
| MDR | Tape devices (not 3590s) ; including controllers |
| OBR | Tape devices (not 3590s) ; including controllers |
If the tape subsystem exception report indicates that corrective action is necessary, the summary reports provide the details required for correction.
The errors may relate to the megabytes processed and depend on product type and usage.
Set the values for temporary errors in the LIMIT control statement so the reports can be used as a maintenance tool. Refer to your MI manual for additional information.
Look for temporary errors that cause system degradation.
