Install and configure the LTO4 drives. Then label/checkin LTO4 tapes and create new Tape Stg Pools. Then take an existing Mgmnt Class and point it to new tape pool. Data will then go there and gradually expire on old tape pools. Depending on how much space you have in 3584, you may then want to Migrate data from LTO1 pools to LTO4 pools this will get rid of old tapes quicker. Don't forget offsite pools also. One main thing is to balance number of LTO1/4 drives to make this work well. Do you have a choice of replacing some of the LTO1 drives now and the rest later? That would help. I would not try to do all pools at once, do 1 or 2 to start and then others as you have resources and see how this is working. There are a few other items, but that covers the basics. David Longo >>> TSM User <[EMAIL PROTECTED]> 6/5/2008 9:34 AM >>> I'm trying to find the best way to migrate a 3584 library from LTO1 to LTO4 media. For a period of time, both drive types will be installed. I know the library can be partitioned, but capacity is already pretty tight, and it would almost certainly require continuous "redrawing the borders" as the relative proportion of media types shifted, in order to make everything fit. Would there be any gotchas if I defined both device classes to the same library, and then assigned the LTO4 scratch media to the appropriate storage pools immediately on checkin? Or am I required to do some kind of library partitioning to make this work? I've done some searching online, but can't find anything explicit one way or the other.
