There has been several discussions on this recently. In brief, most likely the reclamation is slow when input is disk and not tape - an output tape with no input tape. Going tape to tape is MUCH faster. It is a basic TSM design problem that is accentuated by LTO start/stop.
Simple solution is to have disk pool emptier so reclaims will not use disk as input for long. I have 3584 also. Everything else is very fast with this library. David Longo >>> [EMAIL PROTECTED] 07/03/02 09:40AM >>> Hey there Maybe its because I'm used to using STK 9840 tapes but yesterday I saw an LTO tape at 25 % utilisation take almost 4 hours to reclaim, which to me is awful. How am I supposed to reclaim my tapes with that kind of performance?. The drives I use are IBM Ultriums in a 3584 library. With only 2 drives it makes it hard for users to do restores... Are there any options I can change to make this go a bit faster. I know the start/stop on LTO's isn't good. Thanks for the help.
