Explanation
At the end of processing a FREEVOL AGE(0) command,
this message alerts system personnel that data might still remain
on volume
volser. The data remaining on the volume
may include
four categories of data not moved
when FREEVOL AGE(0) is specified. The
four categories
of data are:
- BACKDS backup versions
- Migrated data sets associated with a management class defined
for AUTOBACKUP and are not yet processed for backup versions
- Data sets that may have been recalled, deleted, or moved to ML2
tape, during the FREEVOL processing of this volume
- Fast Replication catalog information data sets,
identified by the second qualifier of HSMCIDS, cannot be moved by
a pre-V1R11 DFSMShsm.
count does not include the
VTOC, the
VTOC index data set,
or SYS1.catalog entry.
count includes the volume
SDSP data set, if found, and may include data sets that have been
recalled, deleted, or moved on to ML2 tape while this FREEVOL command
was processing. Message ARC0550I is followed by message ARC0523I.
Note: DATA SETS refers to individual DSCBs found on the volume. VSAM
data sets may have multiple DSCBs.
System action
DFSMShsm processing continues.
Programmer response
Before removing the volume from the system,
look at the data sets remaining on the volume to determine if any
of them must be kept.
When the remaining data on the volume
contain only BACKDS backup versions, run AUTOBACKUP on the DFSMShsm primary
host to remove them from the volume.
When the remaining data
on the volume contain migrated data sets for which the backup requirements
are not yet satisfied:
- Run AUTOBACKUP on the DFSMShsm primary host— to cause a
backup version to be created of migrated data sets for which backup
versions are yet needed. This process also removes any BACKDS backup
versions from the volume.
- Then reissue the FREEVOL AGE(0) command—to remove the migrated
data sets (those just backed up) from the volume.
When the remaining data sets on the volume
are DFSMShsm Fast Replication catalog information data sets, reissue
the FREEVOL AGE(0) command on a z/OS® V1R11
or later DFSMShsm to move the data sets. Loss of these data sets
restricts the recovery of data sets from associated copy pools.
When the remaining data sets on the volume have retained
backup copies, reissue the FREEVOL command on a z/OS V1R11 or later system.
System personnel
must deal individually with any remaining data sets that must be kept.
