ARC1058I

Explanation
 The HBACKDS command was issued with the parameter
CHANGEDONLY. To determine whether dsname was changed
since the last backup, DFSMShsm tried retrieving the data set’s
VTOC entry. The OBTAIN function encountered an error trying to retrieve
the VTOC entry for dsname.
 If the HBACKDS
command specified a data set filter, then dsname can
be the name of the data component of a VSAM cluster with a name matching
the filter.
 If dsname is uncataloged, then DFSMShsm tried
to retrieve the VTOC entry from the volume specified on the HBACKDS
command. If dsname is cataloged, DFSMShsm tried to retrieve the
VTOC entry from the first volume indicated in the catalog entry.
 The
values for retcode are:  Retcode
Meaning
4
The required volume was not mounted.
8
The data set VTOC entry was not found in the VTOC of the specified
volume.
12
A permanent I/O error was encountered, or an invalid VTOC entry
was found during the processing of the specified volume.
16
There was an invalid work area pointer.

System action
 DFSMShsm treats dsname as
unchanged and does not try to back it up. Processing continues on
any other data sets or filters specified in the HBACKDS command.

Programmer response
 If retcode is 4, correct
the problem and reissue the HBACKDS command, deleting from the command
any data set names and filters backed up the first time. If retcode is
8 or 12, first ensure you spelled dsname correctly;
if so, then notify the system programmer to take corrective action.
If retcode is 16, notify the storage administrator
to take corrective action.
