If so, you want to change the RESERVE to a global ENQ by including the qname/rname. But that may not be best for performance (especially for GRS RING). Also, you can just let the reserve happen (as long as you aren't sharing the volume with other data sets that get reserved). But you don't want it to be reserved 100% of the time. This is controlled by the HOLD parameter in the MASDEF. For example, code HOLD=1000 in your test LPAR. See the fine manual for details.
