Before performing an ARECOVER execute or verify for a particular set of ABACKUP output tapes, issue an ARECOVER PREPARE command to create an ABR record for this recovery. This record contains an inventory of aggregate recovery activity for the aggregate version and allows you to use the simplified ARECOVER command syntax described in the ARECOVER command: Recovering a specified aggregate group when you actually perform aggregate recovery.
The DATASETNAME(dsname) parameter determines the control file data set name. You can use DSNAME as an abbreviation for DATASETNAME.
VOLUMES and XMIT are mutually exclusive parameters. VOLUMES (UNIT is optional) specifies that the volume list be used to allocate the control file to be read. XMIT specifies that the required files must already be cataloged, and the system supplies the volume list.
PREPARE, VERIFY, and EXECUTE are mutually exclusive parameters. When PREPARE is specified with the ARECOVER DATASETNAME(dsname) command, the ABR record is created without verification processing or data movement. When VERIFY or EXECUTE are specified, an ABR record is created if it does not exist.
