Hello,

I need to better understand the different values of stgpools, related to
reclamation processes:

A.- for volume 001894 (see below), how is it possible that % utilized =
90.3 and % reclaimable = 94.4 ? Total should be 100% !!

       Volume 000018 seems to be ok, total 7.9 + 92.2 = 100 %

B.- reclamation threshold of 92% will provoque reclamation process for
volume 001894. How many bytes of data will be moved?
     Is it 1246.0 MB x 90.3% or 1246.0 MB x (100-94.4)%?
     In other terms, how many bytes of used data are still on the
cartridge?

Thanks for your explanation...
