I would ask first, how do you know it is affecting the Prod LPAR. What evidence, RMF Reports, Performance monitors, etc. ?
There should be, I think, so data that could explicitly show that is what is happening. Is it all the time, some of the time? Is it a specific time when the prod LPAR is affected? How long has it been going on? Is there a point in time when this started? If so, what changes occurred at that point?
