When using BRMS, the media policy defines the media class. This media class will define the density of media. Most IBM Tape drives allow writing to media N-1. This means that there may be mixed cartridges in a tape media library or in rotation. As only a single media class can be specified in a media policy, if a different media class needs to be used, the media policy needs to be changed.
A new data area, QUSRBRM/Q1ACLSNONE is provide that will allow the selection of any media class that is available in the tape media library or loaded in a tape drive.

NOTES:
- Specify *NONE for the media class in the media policy
- Once a density is selected, all additional media being selected in the current job will have to have the same density (cartridge type - LTO).
- No mixed densities (cartridge types - LTO) within a media set
- If doing parallel saves, all the cartridges will have to have the same density or cartridge type (LTO)
- The following PTFs or their superseding PTFs are required:
