Remove Tape Library from DPM RRS feed

  • Question

  • I'm in the process of decommissioning a tape library and was hoping to get some guidance. I have ensured that no data is stored on the library (all tapes are marked as free) and that no jobs are trying to use it (it has been disabled for two weeks) and I'm now to the point of physically removing the device. However, I don't see any obvious was either through the admin console or through PowerShell to remove it from the configuration. Is there something that I need to do? The server connects to the library via iSCSI if that matters.

  • Hello Dennis,

    This is still one flaw in DPM, there's no option or supported method to remove a tape library/obsolete devices from DPM.

    When you remove these devices physically, they should be removed from DPM and it should not harm DPM, however entries will still exist in the DPM database, but just ignore them.


    Best regards,

  • That is discouraging. I will remove it and let you know how it goes. Thanks for the quick response.

  • You should be able to remove it so that DPM no longer sees it by going to Device Manager and uninstall the tape library under Medium Changer Devices. Then uninstall the tape drives under Tape Drives. Restart the server and DPM should not detect a tape library.

  • Yes, the only clean way is to uninstall  is by uninstalling the drivers from the Device Manager, and uninstall any software that came with the tape device. 

    Disconnect or remove the iSCSI connectors for the tape library and then restart the DPM server and you shouldn't see the tape library in DPM anymore.

    One thing to note is that if you use reports in DPM, they might show up there.
