This chapter describes the CA-1 to Control-M/Tape conversion process. A brief description of the differences between CA-1 and Control-M/Tape is followed by detailed conversion steps.
CA-1 stores volume and dataset information in the Tape Management Catalog (TMC). The TMC contains volume information in the TMC Volume Record, and dataset information in the Data Set Name Block (DSNB). CA-1 uses a Retention Dataset (RDS) to define customized retention policies and a Vault Pattern Description Dataset (VPD) to manage volume movement between the library and other storage locations.
Retention management and vault management are performed during TMC batch processing. CA-1 also performs Scratch Pool management based on user groups and user applications.
Control-M/Tape volume and dataset information is stored in the Control-M/Tape Media Database (MDB). When a dataset is created, Control-M/Tape records the dataset attributes in the relevant dataset record in the Media Database and updates the appropriate volume record. Dataset access is tracked in both records. Each time a dataset is accessed or created Control-M/Tape searches for user-defined rules that indicate action that must be taken. As Control-M/Tape rules are processed, changes to media management attributes (e.g., vault patterns and retention periods) are updated in the Media Database.
The following diagram indicates how the major CA-1 components are converted to Control-M/Tape format.
