Lock Manager incompatibility between PI and IRLM

We are implementing IMSPLEX configuration for a customer (see diagram attached). Currently we have IMSP instance running on MVS2 LPAR and we are going to add IMSO (IMSP clone) into another new LPAR, using Shared Databases and Shared Queue. See details in teh attached presentation. The current IMSP is still using Program Isolation (PI) and we know the first step to IMSP participate in a IMSPLEX configuration is to migrate to IRLM.

Before migrating IMSP to IRLM, we brought IMSO up on MVS4 with no workload (No BMPs, No MPPs) to fix and improve any wrong parameter in the IMSO. IMSO is using already the IRLM. 

After few days alive, one of the IMS database online reorganization jobs issued a /STA DB command for some databases and the databases became unavailable for IMSP and IMSO (DFS047A unauthorized). see details in the attached word. We took a while to realize the issue was caused by PI-IRLM compatibility since the messages are not clear. Meantime, the production environment was unavailable for the users.

My suggestion is to create a clear message for PI-IRLM incompatibility for the futures sites still using PI and migrating to IMSPLEX with database sharing.
