I noticed a strange behavior since an upgrade to Veeam 8.
There is one backup server with a local repository and an integrated tape drive, which can hold only one tape. The tape job runs every night and has a single Media Pool as a target with all available tapes. Every Morning the tape gets changed to the next one in the rotation.
The problem is, that after the tape change, the drive gets duplicated in the "Tape Infrastructure" view, both of them with the same Drive ID, both show tape media as online (the tape that got changed and the new one). The next day it duplicates again and shows 3 tape drive with 3 different tapes, once I saw up to 5 drives. Sometimes those "fake" drives vanishes without any input in no specific order. Sometimes one "fake" drive shows me tapeX, but when I wait a minute or so it changes to tapeY, if I click somewhere else in the navigation and then back to the online tapes it's tapeX again.
I created a support case about that and was told, that the tape needs to be ejected manually in the Veeam console before changing it. The problem is, that nobody at the site of the backup server has access to Veeam. I am just monitoring and operating Veeam. I am also not very satisfied with the statement of the support. They made is sound like it's an expected behavior, for me it looks more like a GUI bug, because of its randomness.
This happens since a week or two after the upgrade from 7 to 8, never noticed it before. I didn't found anything in the documentation or the knowledge base about that, maybe it's not that expected and someone can tell how to fix it, maybe the database is a bit messed up.
The support case ID is 00974090
