database system error

Hi,

Whenever I want to restore a mailbox that was backed up with granular recovery, I encounter this error, I tried all these steps carefully but again I get the same error.

    I am not an Exchange expert (or NBU for Exchange expert), but I see numerous 'unable to .... '  error messages, e.g
    "unable to successfully enumerate: Microsoft Information Store\Limit Office2013\Database\<user-name> "
    "Unable to open or get value for registry key \HKEY_LOCAL_MACHINE\SOFTWARE\Veritas\NetBackup\CurrentVersion\Config\Granular\CopyLocal, error 2 "

    Just search for the word 'unable' and 'error'.

    Maybe the user name user 'mon-admin1' does not have sufficient permissions? I cannot say.

    Hopefully Lowell_Palecek will have better insight and advice.

    Database system error is a catch-all for "it didn't work." Under the covers, your attempt to open the "Microsoft Information Store" node becomes a bplist request to bprd, which turns it into a Q_IMAGE_LIST_FILES query to bpdbm. If bpdbm doesn't find any files matching the request, you get this error.

    The fact that you are failing at the MIS level indicates that nbfsd is not in the picture - at the browse side. Your backup didn't back anything up. You should see a hierarchy as follows starting at the MIS level:

    Microsoft Information Store
       <database name>
          Database
             <mailbox name>
             <mailbox name>
             ...
       <database name>
       ...

    Nblbc and nbfsd are not involved until you drill into a mailbox. The databases and mailbox names should have been catalogued at backup time. Bpdbm would then retrieve them without any need to involve nblbc on the client.

    Look into your backups. Start with the bpfis log and see if it says no databases were found that match the backup criteria.

      Hello,

       

      Please check first that:

      -The backup is succussfull (status=0), no warning/error message in the detailled status.

      -bpclntcmd -pn from your exchange nodes & the media server (the ouput?)

       

      We faced this problem before and the root cause behind it was that the configuration of hosts files on all 'Master, Media and both exchange nodes) must have all the entries because the bpclntcmd didn't respond , i.e:

      Master server's IP       NBUMASTER              NBUMASTER.FQDN

      Media server's IP        NBUMEDIA                  NBUMEDIA.FQDN

      Node1's IP                  NODE1                         NODE1.FQDN

      Node2's IP                  NODE2                        NODE2.FQDN

      after these changes, run bpclntcmd -clear_host_cache on all those hosts

      check NFS on media server.

      Client for NFS is running

      Server for NFS is stopped and disabled.

       

      Rememeber ! : After editing hosts files, run bpclntcmd -clear_host_cache

        Marianne Hamza_H Lowell_Palecek Hamza_H 

        Whenever I want to expand a mailbox from the list I encounter this error( look at the picture ):

        And as you know this error has a solution , mentioned in this post

        ( https://www.veritas.com/support/en_US/article.100014437 )

        if this link doesn't work, search for this KB Number : 100014437

        and the solution provided in this KB is : "

        Add the Distributed Application Restore Mapping entries to the disaster recovery master server host properties."

        which I did and I've added Mapping Entry in that dialog box .

    As per the TN, you need 'nbfsd log on the client on which you have launched the Backup, Archive and Restore GUI'.

    Please copy this log to nbfsd.txt and upload as attachment.
