Bill, that display may not be the answer you need. As someone else mentioned it does not show anything related to 4K frames.
So first I have to ask. You mentioned DB2 buffer pools. Will the change you want to make go into the 1M LFAREA? If so, then display you have will help. It looks like you have room in the 1M LFAREA to allocate additional buffers. Based on the message your 1M LFAREA is 32.0GB with the max used of 26.6GB. If you DB2 change will not go into the LFAREA then you really need to understand how your remaining storage is being used. Is the lpar doing any paging? If not, then maybe you have room to add additional DB2 buffers. A little paging on a lpar is not necessarily a bad thing. Do you have some type of performance monitoring software? If so, then maybe you can use it to get some snapshots of how your memory usage is going. Do you have access to SMF data and maybe something like MXQ or maybe some other tool that can read the SMF data and report on storage usage? You could possibly run some reports to see how your memory/storage usage was going over time. Good luck..
