CBR6429I Error writing OAM tape [sublevel 1 or backup | sublevel 2] object object-name, collection collection-name in storage group storage-group-name to MVS scratch tape volume volser. The volume capacity volume-capacity [KB | MB] is less than the object size object-size KB. [DATACLASS | L2DATACLASS]=data-class-name, [TAPEUNITNAME | L2TAPEUNITNAME]=tape-unit-name. OAM return code=return-code, reason code=reason-code.
Explanation
An attempt to write object object-name, collection collection-name to tape failed because the volume capacity volume-capacity of the MVS™ scratch tape allocated is less than the object size object-size.
Existing OAM group and OAM scratch tape were not capable of satisfying the write request to tape, so an MVS scratch tape was allocated based on the SETOAM [TAPEUNITNAME | L2TAPEUNITNAME] tape-unit-name and [DATACLASS | L2DATACLASS] data-class-name parameter values defined in the CBROAMxx PARMLIB member or updated by the MODIFY OAM,UPDATE operator command for storage group storage-group-name.
If volume-capacity is followed by a KB, volume-capacity is in KB and the amount of KB is less than 2GB. If volume-capacity is followed by an MB, the volume-capacity shown is in MB because the amount of KB is equal to or greater than 2GB.
The return code return-code and reason code reason-code are internal information that is included in this message for diagnostic purposes only.
System action
OAM fails the write task and continues processing. All future [tape sublevel 1 or backup | tape sublevel 2] writes to storage group storage-group-name for objects greater than object-size KB that require MVS scratch tape allocation fail until OAM is reinitialized or the data class or tape unit name for the storage group are updated using the MODIFY OAM,UPDATE operator command.
The MVS scratch tape allocated, volume volser, is added to storage group storage-group-name and might be selected to satisfy future write requests of objects less than volume-capacity [KB | MB] in size.
Operator response
Notify the system programmer.
System programmer response
- For sublevel 1 or backup tapes,
- Modify the DATACLASS, or TAPEUNITNAME, or both in CBROAMxx, then restart OAM, or
- Modify the DATACLASS, or TAPEUNITNAME, or both, using the MODIFY OAM,UPDATE operator command.
- For sublevel 2 tapes,
- Modify the L2DATACLASS, or L2TAPEUNITNAME, or both in CBROAMxx, then restart OAM, or
- Modify the L2DATACLASS, or L2TAPEUNITNAME, or both, using the MODIFY OAM,UPDATE operator command.
To find information about appropriate capacity values for volumes, see the "system programmer response" for message CBR6419I, or Appendix C of z/OS DFSMS OAM Planning, Installation, and Storage Administration Guide for Object Support.
If objects less than volume-capacity are not directed to this sub-level, consider returning this tape volume back to MVS scratch tape using the MODIFY OAM,MOVEVOL command with delete keyword.
