The CTTSYNC utility automatically performs synchronization with all other automated tape libraries used at your site, such as IBM and StorageTek. The RBTTYPE CTTPARM parameter determines which automated tape libraries to synchronize with the Media database.
For more information about the automated tape library and Control-M/Tape support, see the chapter that discusses the automated tape library interface in the Control-M/Tape Implementation Guide.
The following synchronizations are available between the Media database, automated tape library database, and virtual tape server database:
Checks and updates the status (that is, SCRATCH or ACTIVE) of volumes in the automated tape library database, according to their status as indicated in the Media database.
Checks the automated tape library database to determine whether a volume is currently in the automated tape library. If the volume is in the library, verifies that the IN-ATL flag is set in the volume record in the Media database. If the volume is in the library, also updates the LIBRARY field in the volume record of the Media database to the library name where the volume resides.
For volumes controlled by OAM, updates the SMS Storage Group field (SMSSG) of the volume record in the Media database according to the volume storage group that appears in OAM database.
Checks and updates the volume type field (VOLTYPE) of a volume in the Media database to LOGICAL, if the volume is a logical volume that defined an IBM Virtual Tape Server (VTS) or StorageTek VSM.
Note: Depending on the automated tape libraries in use at your site, the CTTSYNC utility usually updates information about the internal location of each selected volume within the automated tape library.
