Management Classes and Storage Classes

Management Classes - In order to enable Control-M/Tape to identify DFSMS-managed tape data sets, Management classes must be defined for all these data sets. These management classes can be used as part of the selection criteria that trigger a Control-M/Tape rule.

The following management class attributes are referenced by Control-M/Tape to determine the retention for a DFSMS-managed data set:

• Expiration attributes (Expire After Days Non-Usage, Expire After Date or Days)
• Retention Limit
• # GDG Elements On Primary

For more information regarding the Control-M/Tape handling of DFSMS Management classes, see the description in the organization and administration chapter of the Control-M/Tape User Guide.

Storage Classes - Ensure that each DFSMS-managed tape to be handled by Control-M/Tape is assigned a DFSMS Storage class. DFSMS activates the Management Class ACS routine only if a Storage Class is assigned to the data set.
