hallo jack, no need to worry about reclamation of disk storage pools at all. (Primary) disk storage pools will be emptied according to their migration limits as set by you. Maybe you should read TSM documentation, there is a nice chapter about its concepts in one of the books (sorry, I forgot where exactly, but it is easy to find) best regards Juraj Salak -----Urspr�ngliche Nachricht----- Von: Jack McKinney [mailto:[EMAIL PROTECTED]] Gesendet am: Mittwoch, 2.

Firstly, is there a FAQ associated with this list? I have a feeling this question may have come up before... How do DISK volumes reclaim unused space? On a tape, since you cannot write to the begining of a tape you are reading from, you have to copy the data to another tape to reclaim. On a disk volume, this should not be necessary, since you can copy data from the middle of a volume to the begining of the volume. I just installed a new TSM server here with disk volumes as the primary storage pool. Should I be worried about reaching the "end" of the disks? Will TSM fill the "holes" in each volume with new data, or will it shift all of the data to the beginning of the volume, just moving the holes to the end of the volume? If not, should I put one of the volumes into a separate storage pool and then tell TSM to reclaim my main disk pool to this second pool, and have that pool migrate back to the main one? I would hate to do this if it was not necessary, since it would waste a lot of good space for backups. OTOH, I'd hate to put ALL of my disks into the one storage pool, and then be unable to do backups due to lack of reclamation... Right now, I have some disks that I have not used, yet (once a part arrives, I am going to mirror the original volumes). If I wait until we have filled the disk storage pool and see what happens, I can then recover if backups stop by using one of the other disks as a reclamation pool. I'd rather not trial and error on a production server, though... -- "There are two kinds of spurs, my friend: Jack McKinney Those that come in by the door, and [EMAIL PROTECTED] those that come in by the window. http://www.lorentz.com -Tuco, The Good, The Bad, and The Ugly 1024D/D68F2C07 4096g/38AEF076
