Hello all,

I'm relatively new to TSM, and inherited a 3.7 server on AIX with one
3570 library (19 tapes).  We do oracle backups and Solaris/Linux/Aix/NT
backups to the same storage pool.

The problem is we're backing up up a lot of data.  Occasionally TSM will
use up all the tapes, leaving no scratch volumes.  I have expiration set
to run every 6 hours, but with no scratch volumes, space reclamation
fails, and TSM is sort of stuck.  At this point i have to manually move
data from one volume to a disk storage pool, to get an empty volume (or
scratch tape) so TSM can get enough "breathing room". Then reclamation can
free some volumes.  But in the meantime all the previous night's backups
failed.

What is the best rememdy for this?  Should i lower the reclamation
threshold? It is at 60 now...  Also i have plenty of disk space to play
with.  Should i define a reclamation storage pool??  The redbook says a
reclamation storage pool is good for when the library only has one drive,
but it seems it might help in my situation.  Thanks for any advice..

-Ray
