Displaying SMS class definitions during ABACKUP and ARECOVER
During DFSMShsm ABACKUP processing, a list of SMS construct names—along with individual class definitions for the SMS data, management, and storage classes associated with the data sets in the aggregate group being processed—are written to the control file.
During subsequent ARECOVER processing, a message is issued to the ARECOVER activity log listing the attributes of each SMS data class, management class, and storage class definition present at the ABACKUP site. This allows the recovery site to make any necessary changes to either existing SMS constructs or the SMS environment.
If, however, it is determined that the ABACKUP activity log has
been recovered by the ARECOVER command specified with the ACTIVITY
parameter (see Backing up and recovering the ABARS activity log), the SMS construct definitions
are not listed in the ARECOVER activity log.
Note:
- Use the VERIFY or PREPARE option of the ARECOVER command before the EXECUTE option. By doing this, you can determine SMS class definitions, and any needed changes can be made to the SMS environment before actual data movement.
- Use the ACTIVITY option for ARECOVER as an alternative method of retrieving the SMS construct information (see Backing up and recovering the ABARS activity log). By using this method, you can obtain SMS construct information from the ABACKUP activity log, if DASD logging has been specified.
