MAREN causes tapes to be exported in the following events:
Exporting a tape
The MAREN user (or the MAREN administrator on behalf of the user) borrows a tape to another user and exports it as follows:
//EXPORT-VOLUME VOLUME=...,EXPORT-ADDRESS=...The tape thus leaves the area of the local data center.
MAREN checks whether the user is authorized to export the tape. Following this, MAREN instructs the archive system to make the tape available in the input/output unit. It can be exported from there.
Reserved tapes from the local data center are marked as exported in the MAREN catalog, i.e. the current date is entered as the export date in the catalog entry field EXPORT-DATE.
Foreign tapes are removed from the MAREN catalog.Free tapes (VOLUME-STATUS=FREE) cannot be exported.
Relocating a tape
The MAREN administrator can move the tapes to another location in a MARENADM clear-up run.
To do this, the MAREN administrator or the user enters the target location:
//MODIFY-VOLUME-ATTRIBUTES VOLUME=...,LOCATION=PARAMETERS(HOME-LOCATION=<target-location>)The administrator then starts the relocation with:
//RETURN-VOLUMES VOLUME=...,FROM-LOCATION=<robot-location>,TO-LOCATION=<target-location>,MESSAGE-DESTINATION=...MAREN displays a corresponding transport message at the output device specified with the MESSAGE-DESTINATION operand.
In order to accelerate execution, the range of volumes affected should be limited by means of the operand VOLUME=*INTERVAL(...).
The usual request for relocation (
MAR4164) is displayed for each tape to which the conditions apply, and the archive system is instructed to move the tape into the import/export unit.
