1. You can predefine or use scratch.
(Below 5.3 if you are using scratch you are limited to one file system)
We have multiple 1 TB file systems on 5.2.2.4 so we've predefined all of
our volumes (via define volume).

Have you seen the Disk only Backups presentation?

2. Reclaims are exactly the same as Tape reclaims - set your reclamation
threshold and reclamation will be done for volumes that meet the
criteria.

Tim:

We are looking at using all disk now for our onsite disk pool with our
next capital$ buy.
Something I've never been sure of -
Whenf you use a type=file devclass for backups,

1) Do you predefine volumes somehow, or just let TSM create a new one
after the first hits max capacity?
2) Do reclaims happen by themselves, or do you have to force it somehow?

Thanks
Wanda

It is fixed (somewhere around 5.1.5.2).

OK, after spending a large portion of my day reviewing adsm-l post going
back to
2000, I'm still not sure. Does anyone know if there is still a
performance problem
running reclamation on a DIRMC random access disk pool?
I came across one post that said it was supposedly fixed, but
recommended using
a file type diskpool to be safe.
