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
