Error description
In a CA-MIM 12.5 environment, when performing a MULTI-LPAR SLB Restore of Offload the user receives the ARY#RIO TASK nn ENQ_SYSTEMS ERR message. During MULTI_LPAR processing to avoid a UCB scan issue ARY obtains a series of enqueues; STEP, SYSTEM, and SYSTEMS. When GRSRNL=EXCLUDE (i.e. - CA-MIM 12.5 environment) GRS changes a SCOPE=SYSTEMS to a SCOPE=SYSTEM. Because of this, we effectively enqueue on SCOPE=SYSTEM twice. The second SCOPE=SYSTEM receives a RC=8 (i.e. - this task already requested an enqueue on this resource). When CA-MIM processes the SCOPE=SYSTEMS, it propogates the request even though the calls receives a RC=8. So the fix is to ignore RC=8 because the call does get propogated and in this case does not indicate an error. Note: This bugfix resolves the issue in a CA-MIM 12.5 environment only. Recovery Expert does not support releases of CA-MIM before 12.5.
