Explanation
An I/O error has occurred while processing the
specified data set.
- READING indicates that the I/O error has occurred while backing
up the data set from the source volume during aggregate backup processing.
- WRITING indicates that the I/O error occurred while recovering
the data to a target volume during aggregate recovery processing,
or while writing data to the output files needed during aggregate
backup processing.
- data-set-name1 is the name of the data set
that received the error.
- BACKUP indicates that the error has occurred during aggregate
backup processing.
- RECOVERY indicates that the error has occurred during aggregate
recovery processing.
- AGGREGATE GROUP agname is the name of the aggregate
group being processed (aggregate backup only).
- CONTROL FILE DATA SET data-set-name2 is the
name of the control file specified in the ARECOVER command (aggregate
recovery only).
System action
For aggregate backup, the function ends. For
aggregate recovery, the data set is bypassed and aggregate recovery
continues. The data set name is not written to
the restart data set.
Programmer response
For an ABACKUP failure, see the z/OS DFSMS Macro Instructions for Data Sets to identify the problem. You may not be able to
recall the migration version. In this case, if a backup copy exists,
issue a DFSMShsm DELETE
command for the data set, followed by a DFSMShsm RECOVER command. Reissue the ABACKUP
command after the error is corrected.
For an ARECOVER failure,
see the z/OS DFSMS Macro Instructions for Data Sets to identify the problem. Reissue the ARECOVER command
after the error is corrected.
For specific error return codes
and reason codes associated with the failure, see previous message
ARC0645I in the DFSMShsm secondary
address space activity log for this aggregate group.
