CBR6427I OAM write request for collection collection-name and object object-name on tape volume volume encountered a read buffered log failure. Logically written values will be used instead of physically written values for this write request. Return code=rc, reason code=reason-code.
Explanation
After each write to an IBM® standard or enhanced tape volume, OAM performs a read buffered log to determine the amount of space the object physically used on the tape volume for that write. After a successful write to tape for object object-name to tape volume volume, the read buffered log is not successful. Therefore the logical amount of data written to the tape will be used to reflect the amount of space used on the tape volume. Return codes and reason codes are listed below:
- 04
- Minor error occurred.
- 08
- Major error occurred.
- 10
- Create ESTAE environment failure
- 20
- CBRSRDBL ABEND.
- 30
- Log record not in sense format 30.
- 40
- Unknown media length.
- 50
- Read Buffered Log I/O ERROR.
System action
Processing continues.
System programmer response
If read buffered log failures continue, the device returning the errors will have to be evaluated for a solution, and OAM will continue to use the logical size of objects instead of the physical size of objects, when determining how much is written on the tape volume. Using the logical size of objects instead of the physical size of objects will cause tape volumes to be assumed to be more full than they actually are.
