BRMS can play a part in the processing as described above such that the tape volume created is controlled and tracked just like any other BRMS enrolled tape volume.
To do this, you must perform two actions:
The first step is as simple as inserting a tape as is done for save purposes. The second step, using SETMEDBRM, allows you to specify media management parameters to be associated with the written tape. You can specify this command as follows:
Set Media Controls using BRM (SETMEDBRM)
Type choices, press Enter.

The SETMEDBRM command for an output (write) operation, as in our example, allows you to set the following media characteristics:
This command works a little like the OVRTAPF command. You do not see any output. It registers the values you enter, and when an application writes to a tape file, these values are applied to the tape operation.
To find the volume used by the operation, run the following command:
WRKMEDBRM MEDCLS(QIC2GB)When the volumes lists appears on the Work With Media display, locate the volume with the current Creation Date; in this example, TFIL01 was the volume on the tape drive during the processing of the program.

Due to the nature of the method used to get the data on the tape, option 7 (Restore) will not allow you to restore this object. Similarly, there are no saved objects to work with if you use option 9.
