Explanation
A SETSYS command has specified that the 3480 single-file
format is being used. During backup command processing of a data set
to a 3480 tape volume, DFSMShsm has issued a SYNCDEV macro to flush
the tape buffer and write the data to the tape. The SYNCDEV macro
has failed. The data set targeted for backup is named either in the
preceding ARC1001I message, or in the associated ARC0734I message,
containing the return code 69. The ARC1001I or ARC0734I reason codes
are as follows:
- 4
- An invalid device (not a buffered tape) is targeted for the backup
function, or invalid input parameters are specified.
- 8
- A permanent I/O error has occurred during the RDBLKID or SYNCHRONIZE
command.
- 12
- A permanent I/O error is indicated for an earlier channel program.
System action
The backup command fails. The 3480 tape volume
used for output is marked full to prevent its further use, and another
tape volume is selected for the backup procedure. DFSMShsm processing continues.
