DPM 2022 and standalone streamer IBM ULTRIUM HH-7 problem

Hello

I have a question regarding tape backups with DPM. I have an standalone IBM Streamer with which I would like to implement the possibility of making backups in such a way that I will change the tape in the drive myself by hand every day.
I have set up a protection group that carries out protection with disk copy on iscsi hard drives and tape, and interestingly everything works fine, the copy is done, except that the program shows that the operation failed. However, the data is backed up on the tape and on the disk properly
, what's more, it can be easily recovered I tested it. DPM determined the cause of the error with code 3311, I wonder what the problem could be, maybe it is that DPM cannot eject the tape by itself? Anyone have any idea? , thank you in advance.

    Hello Comel,

    I would recommend to check the details of the error as they may contain more information, such a 0x...... error that would be more precise.

    What is clear is that is something related to the tape information on DPM, for information the 3311 error may include:

    The tape is stuck in the drive.

    The home slot of a tape currently in the drive is already occupied by another tape.

    -A tape dismount failed.
    -The tape was decommissioned.
    -There has been a network failure.
    -Permissions to the protected object are not available.
    -The tape is marked suspect.
    -Data on the tape is corrupt.
    -The tape drive is not operating correctly.
    -The tape drive is not online.
    -The tape may have read or write errors on it.
    -There is no free tape in the drive.

    My best judgement tells me that either it is related to some setting on the IDM Streamer related to the Manual action (DPM will complain that can't expell the tape by itself) or that the tape may have been marked as suspect for other reasons.

    I would suggest to get in touch with ther manufacturer to review the proper settings in the Hardware to allow your operation while not giving.

    If you want to try to repair a suspect drive you can attempt the next:
    -Shutdown your DPM software
    -Dump all your tapes out of your library
    -Run as a script the next (paste the commandline it into a text file and changing the extension to .cmd):
    osql -E -S localhost\MSDPM2010 -d DPMDB -Q "UPDATE tbl_MM_ArchiveMedia SET IsSuspect = 0"
    Run the script on your DPM server
    Start DPM 2010 and do a "rescan" under the Library Tab.
