BTW, with PDSESHARING(NORMAL), PDSE can be shared R/W outside the sysplex, but the boundaries must still be within the GRSplex. However, they can't be shared R/W between systems managed by MII (MIM) because the ENQs issued for SYSZIGW0 and SYSZIGW1 are issued with RNL=NO. IIRC, this wasn't always the case and IBM "broke this" for CA MIM customers around DFSMS/MVS 1.5. Thank you IBM.
