What level are you setting for reclamation. I have found that in a catch-up situation, it is best to set the reclamation level high (e.g. 99 or 98) and get the easy (almost empty) tapes first, and then step the value down over time until you get caught up to a level you want to be at. This was with collocation on for both primary and copy pools so your experiences may be different. But TSM spends time at the beginning of reclamation figuring out which tapes and the best way to process them ( I believe it tries to minimize tape mounts) so starting high makes that part of the process go faster.
David >>> "Moyer, Joni M" <[email protected]> 1/27/2010 8:53 AM >>> Hello everyone, For several years I had not been able to run reclamation on one of my tsm servers due to the lack of physical tape drives to accomplish the task. I am in the process of trying to get caught up, but it seems that I just never do. Most of my issue is with the copy storage pool volumes which are very under-utilized. It seems like reclamation, even if I start multiple reclamation threads, is taking quite a long time. Is there some other way for me to get the data onto new media without doing reclamation? Can I do a move data from 1 copy storage pool volume to the another volume within the same copy storage pool? I know that this would mean bringing the tapes back from the vault, but it is just not progressing as I would like with the reclamation processes. Any suggestions are greatly appreciated as I would like to get this back under control. Thank you in advance!
