Using multiple tape media libraries for a parallel save
If planning on doing parallel saves using multiple tape media libraries, users should use *MEDCLS rather than specify the individual tape media libraries in the control group attributes or in the the DEV parameter on the SAVxxxBRM commands
If there are multiple drives available in the first tape media library selected, and it the Min/Max requirements are met, BRMS will use only use the one tape media library
Media policy must be set to use *ANY for the location of media.
Tape media libraries need to have unique locations (WRKDEVBRM) and available media needs to be at those locations
Tape drives in the different tape media libraries have to be write compatible with each other
It is important to only specify *MEDCLS once for the Backup Devices or DEV parameter
