Wanda,

I just added a sata disk array in TSM v5.2 so I'll jump in here.

If you are using one disk partition in Windows for the device class then
you can let TSM define the number of vols it needs up to maxscr or out
of disk condition. Each volume name will be unique and assigned by TSM.

If you use more than one one disk partition for the device class you
need to dsmfmt as many volumes as you need and you must then define
those volumes to the storage pool. Only the volume names you specified
will be used and reused.

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.
