  • oper_20_4 is left over from an upgrade from 5.x to 6.x It should have been fixed back then.

    There is a 'merge table', one of the tables in NBDB, which was to deal with 'probelm' entries between the upgrade to 6.x, where the entries relate to tapes.  

    File 731.dat in the nbcc output is the merge table in the version of NBU you have (.dat files can change between versions).   You can also list media in the merge table with nbemmcmd -listmedia -mergetable  - the outputs should match.

    If I rightly remember, you have two conflicting entries for the same tape, only one will be correct.

    Technically, nbcc is only needed to upgrade from 5.x -> 6.x, after that it is optional, that is, nbcc issues when upgrading from 6.x to higher shouldn't cause a failure /problem with the upgrade (despite there being an nbcc -upgrade option).  Not fixing nbcc issues can however cause issues with the operation of NBU and can lead to dataloss.

    Merge table entries are one of the things that are meant to be fixed, not really optonal - nbcc stops repoting any futher issues until oper_20_4 issues are resolved.

    The only supported way to fix this is via nbcc.

    Given there are merge table issues, I suspect there will be many other nbcc issues - some of these could put data at risk and so the only real way forward is to get a valid support contract and work through nbcc properly.

      Thanks mph999,

      The "CONSISTENCY_ERROR Oper_20_4" message desapeared with the following commands (21 old medias removed): 

      nbemmcmd -listmedia -mergetable
      nbemmcmd -deletemedia -mediaid [XXXXXX] -originhost [masterServerName]
      nbemmcmd -deletemerge -assignedhost NONE -mediaid [XXXXXX]

       

      But, like you had supposed, inconsistency keeps. Now, I believe that there are something wrong with my valid medias. I attached the new result of nbcc command, so if possible, take a look to help me in this case.

      Thanks about nbcc information, otherwise, like you said, it's better to run it to prevent some dataloss, am I right?

       

      Tks,

        Hey

        Do you have any frozen media?? bpmedialist -summary |findstr FROZEN

        if so unfreeze and rerun the nbcc

         

        ----edit-----

        to unfreeze

        bpmedia -unfreeze -m mediaID

        once done for all medias... do the following

        bpimage -cleanup -allclients

        bpexpdate -deassignempty -force

  • hey

    hmm blind try - as i never faced such error

    Why this master server has no tape storage unit? maybe there was some media server which was not properly decomissioned... there is only one STU - catalog stu - basic disk or so...

    maybe 20_4 says that media are orphaned... no clue...

      Hi quebek,

      The result of the commando "> nbemmcmd -listhosts" is correct about my servers and this site has only one master/media server. The tape library is not working and I excluded it. Making the scenario worst, yesterday, my deduplication volume crashed and I had to remove it too. Now I'll try to make another dedup pool, so I'd like, first of all, to upgrade my software until my last registered/compliance version.

       

      Tks,
