BACKUPDEVICECATEGORY: Specifying the backup device for the control data sets and journal

Explanation: BACKUPDEVICECATEGORY is an optional parameter of CONTROLDATASETS that specifies the type of device that receives the backup copies of the DFSMShsm control data sets and the journal when DFSMShsm backs them up.

Subparameter	Explanation
DASD	BACKUPDEVICECATEGORY(DASD) specifies that DASD is the device on which the backup copies will be recorded.
TAPE	BACKUPDEVICECATEGORY(TAPE)specifies that tape is the device on which the backup copies will be recorded. TAPE(PARALLEL) specifies that all control data sets and the journal should be backed up in parallel. By specifying this subparameter, you can cause one tape drive to be allocated for each control data set and the journal. TAPE(NOPARALLEL) specifies that the control data sets and the journal should be backed up serially. When NOPARALLEL is specified, the control data sets are backed up one at a time followed by the backup of the journal. By specifying this parameter, you can cause only one tape drive to be allocated for all the control data set backups. TAPE(NOPARALLEL) may not be specified when DATAMOVER(DSS) is specified.

Subparameter

Explanation

DASD

BACKUPDEVICECATEGORY(DASD) specifies that DASD is the device on which the backup copies will be recorded.

TAPE

BACKUPDEVICECATEGORY(TAPE)specifies that tape is the device on which the backup copies will be recorded.

TAPE(PARALLEL) specifies that all control data sets and the journal should be backed up in parallel. By specifying this subparameter, you can cause one tape drive to be allocated for each control data set and the journal.

TAPE(NOPARALLEL) specifies that the control data sets and the journal should be backed up serially. When NOPARALLEL is specified, the control data sets are backed up one at a time followed by the backup of the journal. By specifying this parameter, you can cause only one tape drive to be allocated for all the control data set backups. TAPE(NOPARALLEL) may not be specified when DATAMOVER(DSS) is specified.

SETSYS Defaults: None.

DFSMShsm Defaults: If you do not specify BACKUPDEVICECATEGORY, the backup device used will be determined by the SETSYS CDSVERSIONBACKUP subparameter BACKUPDEVICECATEGORY. If the SETSYS CDSVERSIONBACKUP subparameter BACKUPDEVICECATEGORY has not been previously specified, the DFSMShsm default is BACKUPDEVICECATEGORY(TAPE(NOPARALLEL)).

Note:

If BACKVOL CDS specifies DATAMOVER(DSS), or if BACKVOL CDS does not specify a datamover and the DFSMShsm CDS Version Backup environment indicates DATAMOVER(DSS), then TAPE(NOPARALLEL) may not be specified.
If you are attempting to backup to tape, ensure that you have previously issued the SETSYS CDSVERSIONBACKUP(BACKUPDEVICECATEGORY(TAPE (UNITNAME(unit))) command to properly configure the CDSVERSIONBACKUP parameter table.
