Hi Dennis, I know for us Dynamic PAV just did not work unless we had both "I/O priority management" & "Dynamic alias management" set to YES in WLM.

In the initial setup we defined in HCD base (3390B) and alias (3390A) volumes with wlmpav=yes (for the aliases). On the storage array we have "Compatible PAV" enabled. In WLM we have Dynamic alias management set to yes. We are running z/os 1.4 and wlm in goal mode. My problem is that I cannot see any dynamic assignment of alias volumes to base volumes with high IOS queuing times. Using HDS Storage Navigator's Compatible PAV manager I see the first 64 base volumes (out of 192) with 1 alias volume in each of my control units. I have yet to see anything change over the past 4 weeks. I would have expected to see maybe a base volume (beyond the first 64) to have an alias assigned especially if the base volume has high ios queuing times (as seen in Omegamon). I can however manually assign alias volumes to base but this is not dynamic management. What am I missing to allow dynamic management of pav's?
