Explanation
During SMS expiration processing, the data set
was found to still be in need of backup. It is not expired until the
backup is done.
DFSMShsm determines a data set is NOT in
need of backup if one of the following situations exists:
- The data set change flag is off in the VTOC entry AND the last
backup date in the catalog is nonzero. Note that DFSMShsm does not verify the
existence of the backup version.
- The data set change flag is off in the VTOC entry AND the last
backup date in the catalog is zero AND the management class does not
request autobackup for this data set.
- The data set change flag is on in the VTOC entry AND the management
class does not request autobackup for this data set.
- The MCVT bit (MCVTNDBU) is on, which indicates bypassing the current
SMS DBU requirement that a backup copy needs to exist before expiring
a data set.
This message is referenced by an associated ARC0734I message.
The name of the data set is included in the ARC0734I message.
Note: ADMIN
OR USER COMMAND BACKUP must not be specified as NONE and AUTO BACKUP
must be specified as Y to request automatic backup.
System action
The individual data set is not expired. DFSMShsm processing
continues.
