I have TSM server 5.4.3.0 and an IBM 3584 library with LTO2/3 drives. Recently installed a Diligent VTL. I have migrated one of my smallest Storage pools to VTL and find one problem. In this Domain, I have one Windows client that takes about 23 hours to backup - 10's of millions of files. With VTL, I got rid of my Disk Pool for this Domain. Now when I do a "Backup stg" from my VTL pool to real LTO tape, it is waiting for Virtual tape that client is writing to. Client only backs up about 5 GB a day, so most times writing little or nothing, however the VTL tape is "IN USE". Is there a way to "breakin" to tape and force new tape to mount? I have looked at TSM server doc and don't see it. I have well over 400 clients and about a dozen are like this, taking well 6-24 hours to backup. Thinking about it some, the only, or the simplest option I see, is to take these dozen clients and put them in a Domain by them selves that will still use a disk pool. Part of the reason for VTL was to get rid of disk pools. (DEDup and faster restores was primary reason.) Anything simple I have missed? (We have already looked at making these clients run in less time, we are stuck with what we have for some time to come.) Thanks, David Longo
