SCRATCH System Option—Volume Scratch Control

Use the SCRATCH system option to determine whether volumes will be scratched by:

• TRS based on the controlling data set (CDS)
• The keep date expiration of all data sets along with all data sets that have been uncataloged from the OS/Catalog
• The keep date expiration of all data sets in the volume chain

This system option has the following format:

SCRATCH=[CDS|ALL]

ALL

Places all tapes to a type 3 control when the keep date for all data sets has expired and all data sets have been uncataloged.

CDS

(Default) Specifies that scratch volumes are based on expiration of the controlling data set.

Important! If the SCRATCH=ALL option is coded in TLMSIPO, tapes do not go scratch after their retention period has been completed unless all data sets on all volumes have met their KEEPDATES and have been uncataloged. SCRATCH=CDS causes the volume to be scratched and uncataloged when the retention period is complete. Types A, B, or C will protect multi-file volumes.

CA Technologies does not recommend SCRATCH=ALL. Assign retention types A, B, or C as needed.

Note: For more information on retention types, see the User Guide.
