VTS Export/Import Interface

VTS (Virtual Tape Server) logical volumes cannot be vaulted unless they are exported onto physical tapes. Control-M/Tape automatically initiates the VTS Export/Import interface to export VTS logical volumes out of the VTS environment and to stack and vault those volumes onto physical tapes.

When exporting logical volumes, Control-M/Tape groups together volumes with similar vaulting patterns. Each group is then written to separate physical tapes to be sent to different vaults, as necessary.

Logical volumes are grouped together for export using one of the following criteria:

• if their first DO VAULT value and associated retention specification (UNTIL subparameter) are the same
• only if the entire vaulting pattern for each logical volume is the same

The criteria used for grouping logical volumes are set with the TYPERUN MODE parameter in the VTSVLTIN member in the CTT PARM library. For more information, see "Implementing the VTS Export/Import Interface."
