Hi,

I have a simple question: is it possible to use the
tape-volumes in a storagepool in a circular way?
What I see now, is that if a volume becomes empty
(after all files have been deleted or after reclamation),
this volume is used before "next" empty volumes
in the storage pool are used.

Example: ten volumes (0-9), volumes 0-5 are used and volumes 6-9 are empty,
if volume 3 becomes empty, it is used before volumes 6-9 are used.
So the 'last' volumes in a storage are never used if 'previous' volumes
becomes empty.
I know you can use the reusedelay parameter, but that's no guarantee
all the volumes are used in a circular way.

(we are running ADSM V2.1 on a SP2 (AIX 4.1.4.0) using 3494 with 3590 units).
