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...

You really can't force TSM into an old-fashioned full-and-incremental strategy, at least not well, and if you're dead-set on trying to do that, then perhaps you should reconsider your choice to use TSM.
