> This at least suggests that IRD Weight Management is also disabled when an > Lpar is softcapped by DC limits and not only by GC limits. Kees: Correct - when an LPAR is being capped, regardless whether that's due to an LPAR level defined capacity, or due to group capacity, IRD won't help the partition.
In the case of LPAR level DC that's likely no problem: The LPAR's 4-hour-rolling-average has exceeded the installation defined limit despite the fact that the LPAR already has a low weight. Granting it even more weight doesn't make much sense. With group capping the situation is a bit different: the LPAR "weight" does also determine the LPAR's entitlement of the group capacity. With "weight" being the current (vs. initial) weight IRD may have contributed to managing the LPAR to a low entitlement. That can sometimes be problematic, e.g. depending on whether the importance distribution of your workload within the LPAR cluster has changed or not, and how long the capping situation persists (with pattern capping there is obviously a much better chance.)
