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..

Paul

I think I found the command I needed:
/F AXR,IAXDMEM

 IAR049I DISPLAY MEMORY V1.0                 
 PAGEABLE 1M STATISTICS                      
    92.3GB : TOTAL SIZE                      
    14.5GB : AVAILABLE FOR PAGEABLE 1M PAGES 
  2469.0MB : IN-USE FOR PAGEABLE 1M PAGES    
  6590.0MB : MAX IN-USE FOR PAGEABLE 1M PAGES
   162.0MB : FIXED PAGEABLE 1M FRAMES        
 LFAREA 1M STATISTICS - SOURCE = IEASYS00    
    32.0GB : TOTAL SIZE                      
  5501.0MB : AVAILABLE FOR FIXED 1M PAGES    
    26.6GB : IN-USE FOR FIXED 1M PAGES       
    26.6GB : MAX IN-USE FOR FIXED 1M PAGES   
 LFAREA 2G STATISTICS - SOURCE = IEASYS00    
     0.0MB : TOTAL SIZE = 0                  
     0.0MB : AVAILABLE FOR 2G PAGES = 0      
     0.0MB : IN-USE FOR 2G PAGES = 0         
     0.0MB : MAX IN-USE FOR 2G PAGES = 0     

Just trying to interpret it and get the numbers I need.............
