Mark - Balancing with the *USAGE option will only move data from disk arms that are "hot" ... I was told by IBM SupportLine that "hot" in this context means the arm utilization is higher than 40% ... If the trace data collected didn't encounter any 'hot' arms, then nothing happens. I've viewed arm utilization spikes in my system too. However, apparently the trace function didn't see it. Maybe the trace collection is smoothing things out by sampling at too long an interval (???) I wish we could set the "hot" value to use and the interval at which to collect trace data, but IBM doesn't let us... or at least I've never found a way to do it.
