Hi Dima P,
The Medium Changer driver is "Sun/Storage Tek Library", Driver Provider "Storage Tek", Driver date "22/06/2009", Driver Version "22.214.171.124".
I received 2 files from the person working on my case:- "VeeamTapeSvc.exe" and "Veeam.Backup.Core.dll". The case owner asked me to try these 2 files as a temporary workaround by making sure I have copies of the original versions of these files->replacing the originals with these 2->restarting the Veeam services->open a command prompt and run the workaround VeeamTapeSvc.exe to import a tape-> replace the 2 workaround files with the originals->restart the Veeam services. This seems to have worked. It imported one of the thirty VTL tapes I had configured in my AWS Console and when I then right-clicked the tape library and ran an import tape operation, it added the remaining 29 tapes into "Online" Media. I was then able to right-click the library and perform an "Inventory Library" and all 30 tapes were marked as "Free". I've just created a GFS Media Pool and a test Tape Backup job linking it to one of my main backup-to-disk-repository jobs and kicked off a backup and it appears to be processing ok. The job started around 25 minutes ago and it loaded a tape into a drive and added it to the GFS pool and the job is showing data processed/Read/Transferred at a rate of 25 MB/s and showing 1% completed.
The case owner told me not to continue using the 2 workaround files, they were provided to me just to get the import to work via command line. Hopefully this will become a permanent fix and incorporated into the product....
