Tape list only contains one tape listed as offline RRS feed

  • Question

  • I'm trying to recover a Hyper-V VM from tape using DPM 2012 R2 however when I click the link to view the tape list only one tape is shown and the library is listed as Offline. I'm using DPM with a superloader tape library containing 8 slots, each with a tape and DPM has had exclusive use of this. I don't understand why only one tape is listed. Should the other tapes also be listed? Why might it be listed as offline when it has a status of 'Tape available' in Management> Libraries?

    The text next to it says 'All tapes offline', is this related? Why is this?

  • Hi,

    The tape list is generated only for that recovery point, not all recovery points for that data source.  The Library column is showing OFFLINE because the tape is not located in the physical tape library.  The tape is currently OFFLINE.  You will need to locate the tape based on barcode or tape label and place it back in the physical library and then do a fast inventory so DPM knows that tape in available.  Then when you go back and look at the tape list - it will show the tape library name instead of offline.

  • Thanks it turned out there was a problem with the specific tape it was looking for the backup on and it was listed as unrecognised. Tapes are marked as online when looking at another VM that had a long term recovery point.
