so lots of tapes are utilised < 30% !!!
And some of them are at 100% marked as filling....


 and if 
%> necessary lower the threshold with 'upd stg <the pool> 
%> recl=<something
%> less>'
%> And do not search yourself, there are computers for that 
%> (and search functionality in help). Just find time to read

read this one... :(

Maybe there is a bug?
