Here's what I'm guessing is happening with your tape utilization numbers, as I've seen that here too. Until the tape is actually full, it seems to base it's %full on the "estimated capacity" of the device class. So I'm thinking you probably set your lto2 dev class to 400GB. Once the tape is full, tsm switchs to stating the ACTUAL amount of data it got on the tape. The other peculiarity I noticed is that it doesn't seem to take compression into account in that number. To be honest it's still a little confusing to me as well. It seems to only show native capacity (~200GB), but yet some tapes show a bit more (~235GB), as if it did take some compression into account. That shouldn't be right either though, as I know my data is more compressible than 17%.
>>> [EMAIL PROTECTED] 4/19/2006 6:50 PM >>> Question related to collocation groups: If 10 nodes are in one group will it only mount one tape even if no other tape drives are busy? If I have a directory disk pool that is cached will it still go to one tape after migration or will collocation groups affect that? What I see leads me to believe the answer is yes. I am seeing multiple tapes for the directory tape pool with little to no data. Do folks still use this option? Why do tapes that are not full show capacity of 381GB yet when they go full only show about 200GB? Do I need to force compression on with the drives or something?
