Resolution

It is important to understand that data for Storage Group Allocatio and more specialy  to understand that data for column %Allo in (OBJ02340) SMS Storage Group Allocations are taken from object (POOLS) Storage Groups in LAST INTERVAL mode (the object OBJ02340 is real time - but it takes some values from other objects).

That means that %Allo is updated as frequently as you are doing VOLUMES/POOLS SCAN

- via the interval specified in Vantage system parameter PAWINTVL

or 

- via /F SAMS,NEWSCAN,POOLS or /F SAMS,REFRESH,POOLS modify commands (these command have same function).
