DPM Fails when using expired tapes (ID3311) RRS feed

  • Question

  • We have a problem with our SC DPM 2012R2 (Now Rollup 11, but the problem existed when it was still Rollup 10) server. The problem is that whenever we first (fresh out of the package) use a tape the backup runs fine, but whenever we use a tape that we already used before the backup to tape fails.

    Even when we mark a tape as free or erase the tape it still fails.

    I think our colocation settings are ok, otherwise it would not work with a fresh new tape.

    We also receive a error about inventory failing right when the backup starts. But since we always get this error even when the backup is succesful I don't think its related, I think its because the tape is in use by the backup.

    I ran the DPMTapeLibraryCompatibilityCheckerTool mentioned in several threads and that shows the test as succesful.

    Is there anyone that can point us in the right direction or shed some light on the reason for failing with expired tapes?
