Having problems entering tapes into an IBM ATL that is shared between LPARs that do not share the TMC or VMF? The CA version of CBRUXENT will by default only enter the tapes defined to the TMC/VMF for that LPAR and will leave the other tapes for another LPAR to enter. For each LPAR to be able to enter their tapes you must have a tape drive online for each LPAR.
