Hi Barbara, we have a similar setup....but because we "merged" two production Parallel Sysplexes.
history: 2 separate datacenters in same city. 2nd prod system had been CLONED from first and modified slightly....then had 10 years growth. We also had each datacenter being the DR site of the other. Sovereign RISK! - had to move DR site off country. Now no "reason" for 2 data centers in same city.....so relocate machines from 2nd site to 1st. Then "save money" and merge the 2 separate Parallel Sysplexes into one. End up with 3 x JES2 MASplex / SMSPlex / HSMPlex in single Parallel Sysplex. (that 2nd site has been subplexed always...but only one subset had DB2.) Ok...had to have LOGR.....reasons included heavy DB2 Data Sharing in both original sites. So we set up a pool of DASD that was accessible from every production system. Each SMSPlex was given a subset of that DASD to manage. So each disk volume has only one SMS owner. Set up common User Catalog, connected to each system MastCat. It doesn't matter which LOGR does the OFFLOAD.....because the SMS managed offload dataset is placed onto the shared disk, and cataloged in common UserCat. Been operating like this for 12 months. Probably stay this way for a long time. The migration path from this BronzePlex to the ultimate PlatinumPlex looks almost impossible to complete.
