Jerry, The partitioning available to the host systems is only by category numbers. You dont have to partition, but reasons to create 2 partitions in your case include: - tape management system - if not a single VMF shared between test/prod - TCDB - this must be shared to avoid conflicts of volume status - ICF catalogs containing tape data sets - if not online to both partitions you can get inconsistencies after tape management returns a volume to scratch, or a data set is created on 1 lpar but managed from another. That is why most people partition their system managed tape libraries including those which are virtual and have the dasd cache online to all system.
