I've just installed BE2014 - CASO + MMS - and configured a dedupe store on the MMS.
For some reason the dedupe devices are showing up as 10x Tape drives with a Product id "OstDrv" and Firmware "CAGM" and they're using up the LEO licences installed on the MMS.
There is actually a tape library with 4 drives (two disabled/offline) connected to the MMS
Any ideas on why they're showing up? BE2012 didn't show them. I've checked the registry for the HKLM\Software\Backup Exec For Windows\Backup Exec\User Interface\ShowHiddenMedia key but it's not present.
Where are these OstDrv's showing up?
Dedupe uses these internally as a sort of virtual library where the number of drives equals your dedupe concurency. But they shouldn't show up in the BE gui and they shouldn't be using up your LEO licenses..
The registry key you mentioned is for media, not drives, so that would have no impact.
I don't know if the issues are related, but the screen shot & adamm.log definitely show something is wrong with the IBM 3573 device discovery. The library is reporting that it has 4 tape drives, but BE is only able to see two tape drives.
Are there really 4 drives in the 3573? Are you attempting to use a logical library (aka hardware partitioning)? How many tape drives do you want BE to see & use? Once this is resolved, it may help your dedupe issue.
There are 4 drives present in the library, but only two are connected to the server so this is expected. We have the same setup on another server (BE2012) and it doesn't show the OstDrv devices.
Try this. Disable the client-side deduplication option from the DeDupe folder settings and also set the concurrency to 1. Restart the BE services on the BE media server and the remote agent service on the remote servers. Check if the OstDrv devices are now shown or not in the UI.
