Re: Preparing a tape storage pool volume for reuse

Rob,

I couldn't agree more with Mark. Please read the introduction to TSM.
When I look at the name of your copy storage pool (3581_week2) it seems
that you are still working in a full/incremental way. This is not how
TSM works.
This is about the 'progressive backup' in TSM and  taken from the "TSM
Concepts" Redbook:

"[Progressive backup] Saves time and disk space by backing up only new
files and modified files. The progressive backup feature uses its own
relational database to track data wherever it is stored, delivering
direct one-step file restore. This eliminates the need for
base-plus-incrementals tapes, commonly used for restore procedures in
other storage management products."

Furthermore, reclamation isn't something that 'fits' in your backup
strategy. It is something that is part of TSM and should be used; it has
nothing to do with your backup strategy.

Again, please refer to the Redbooks provided by IBM...

Judging by one of your other emails, is reclaimation a process to merge
partial tapes together?  If so, that really doesn't interest us.  It
doesn't fit into our backup strategy.

Re: [ADSM-L] Preparing a tape storage pool volume for reuse






Rob,

Again this is a fundamental concept in TSM as I stated in my previous
post I think you will need to develop your skill set in the TSM area.

No, you do not want to do DELete VOLume!  What you should be doing on
some regular basis is running reclamation on that storage pool.
Reclamation will then empty the partially used tapes.  Please refer to
the admin guide where you will find several sections discussing managing
storage pools and volumes.
