Explanation
While DFSMShsm has attempted to read the primary
copy of a data set, an I/O error has occurred, or incorrect records
have been found in a variable format data set.
For incorrect
records, a block descriptor word suggests a block size greater than
the record size, a block size less than 8, or a block size larger
than the maximum block size of 32760.
If an I/O error has occurred,
an access method or hardware error message associated with this message
can be found in the DFSMShsm job log SYSMSG data set. The name
of the data set being backed up appears either in the preceding ARC1001I
message, or in the associated ARC0734I message, with a return code
of 16. For the ARC0734I message, refer to the backup activity log.
In Message ARC1001I, the value for the
reascode is:
- Reascode
- Meaning
- 0
- Actual I/O error on input data set.
- 2
- User header label is bad.
- 4
- User trailer label is bad.
- 6
- Block descriptor word (BDW) indicates an incorrect block size.
- 8
- Partitioned data set with no EOF marker after members.
- 10
- Data set not found in SDSP.
- 12
- GENCB error has occurred. If the data set being backed up is an
HFS File System, then one of the following may have occurred:
- HFS is not running. The operator must start HFS.
- The requested HFS File System has been quiesced. The file system
must be unquiesced.
- The DFSMShsm ID
has not been identified as a valid OMVS ID. The ID must be defined
to OMVS as a valid ID.
- 14
- Accumulated count fields indicate more than the allowable bytes
on a track.
- 16
- Record 1 indicates more than the allowable bytes on a track.
- 54
- PDS member has an incorrect record length. See previously issued
message ARC0901I for the member name.
System action
The backup operation ends. DFSMShsm processing continues.
Programmer response
If an I/O error has occurred, respond to
the associated access method or hardware error message. For information
about the block descriptor word (BDW), see z/OS DFSMS Using Data Sets.
