NetBackup 7.1 Media (Device) Manager Won't stay started

 

We recently switched to capacity-based licensing and now our Windows media servers won't start as media servers.  The first symptom of this was that we were having trouble with one of our media servers, so we decommissioned it and re-installed it (following documented instructions from NetBackup 7.1 Administrator's Guide).  I then tried adding the devices through the Admin Console (from the master) wizard, and got the error that it couldn't start the "media manager device daemon", after I've verified that it's able to see the robot and tape drives.  The client is a Windows Server 2003R2 running NBU 7.1 and the Master is a Solaris 10 running NBU 7.1.0.2.
 
Following the troubleshooting guides and this thread, I found that I get the following in the Event Viewer after trying to start the Device Manager manually:
"There are no entries in the drive database. The NetBackup Device Manager service only needs to run when devices are configured. The service will now exit.ce only needs to run when devices are configured. The service will now exit."
 
I've tried to open up a support with Symantec, but when we switched to capacity-based licensing, they mucked something up and now my email is no longer attached to my customer number, and, therefore, licensing.  I have an open case with licensing support to get it fixed, but in the meantime, I really need to get this fixed.
 
Someone (Marianne, mph999?), please help!
 

As you can see below, Shared Storage Option is enabled, as well as Remote Client Support.  (Note that I've obscured the license key.)

  • Seems like a comms issue with mfp01-2.

    Fist of all - you have two separate media server entries for this server - one with shortname and another with FQDN (instead of one entry with emm alias for alternate name).

    Checking with the host "mfp01-2"...
    Checking with the host "mfp01-2.hs.azdhs.gov"...

    When you previously decommissioned this media server, which name did you use - FQDN or shortname?
    You should have one entry only - not both (like with other workin media servers).

     

    Also, returned emtries failed for FQDN and shortname returned FQDN for EMM server where other media servers returned shortname.


    MEDIA          7.1                 mfp01-1                  wayback        
    MEDIA          7.1                 mfp01-2                  wayback.hs.azdhs.gov

    I have learned that consistency works best - either shortname or FQDN - not a mix.

    I have also seen that media servers that cannot be contacted cause all sorts of issues with resource broker on the master server - like jobs queing for long times and long delays between identifying resources and assigning them.

    So, my suggestion is to first of all get rid of FQDN for media server to avoid attempts to communicate with it:

    <unknown>      UNKNOWN RELEASE (-2)mfp01-2.hs.azdhs.gov     <unknown>      

    *Failed to get the configuration for the host "mfp01-2.hs.azdhs.gov". client hostname could not be found(48)
    Try 'nbemmcmd  -deletehost .....'
    Hopefully this will work without issues. If there are EMM device or media or image entries, command will fail.
    Next, get all emmserver entries consistent with:
    nbemmcmd -setemmserver
     
    After all server names have been cleaned up, try to activate mfp01-2 for disk and tape:

    nbemmcmd -updatehost -machinename <media-server> -machinestateop set_tape_active -machinetype media -masterserver <master>

  • I have honestly never seen capacity-based license causing issues....

    Have you entered the same license key on master and all media servers?

    Please post output of these command on master (this will confirm comms with media server):

    nbemmcmd -listhosts -verbose

    nbemmcmd -getemmserver

     

  • I'm not certain it's a licensing issue or not, but that's what all the errors seem to point to.  The same license key is installed on master and media servers, except the mfp01-1, which seems to be working, although I haven't restarted services on it.  mfp01-2 is the one in question.  Mexmb01 also had the same issue, though I can't reproduce it now because services were set up to start as the netbackup user, which our admin seems to have lost the password (but I digress).  Our deduplication server dd01 does not have the problem, and I've attempted to install the same keys (our older licenses, licensed for a count of 8 Windows) on the mfp01-2.

    *Failed to get the configuration for the host "mfp01-2.hs.azdhs.gov". client hostname could not be found(48)
    Try 'nbemmcmd  -deletehost .....'
    Hopefully this will work without issues. If there are EMM device or media or image entries, command will fail.
    Next, get all emmserver entries consistent with:
    nbemmcmd -setemmserver
     
    After all server names have been cleaned up, try to activate mfp01-2 for disk and tape:

    nbemmcmd -updatehost -machinename <media-server> -machinestateop set_tape_active -machinetype media -masterserver <master> 

     

     

     

     

     
  • I will try to get rid of the FQDN.  I don't know where they came from (other admin, maybe?).  I stay pretty consistent in using hostname only.

  • I see that quite often in bigger environments with more than one admin.

    Normally creates major confusion within NBU...

  • that media server (FQDN) shows "not reachable by master".

    If you do a bptestbpcd against that media server, guess it would either hang or return an error.

    I agree with Marianne that hostname resolution needs to be sorted out first. The license could be impacted as it's tied to hostname, try to see if you get error when doing a:

    /usr/openv/netbackup/bin/admincmd/get_license_key

    It will give you error if the hostname you currently use for that media server is incorrect (FQDN instead of shortname or vice versa)

  • After removing the media server from the EMM db, it looks ok, and I can activate it manually for tape and disk, but after I try to re-add the robot and drives via the Admin console, the FQDN shows back up.

  • 1. Try to inspect your admin-logs on master server to check when this record was created.

    2. If your master can't resolve mfp01-2.hs.azdhs.gov and if  mfp01-2.hs.azdhs.gov and  mfp01-2 are the same try to add record into /etc/hosts at master-server.

    3. Try to run on the problem media-server:

    bpclntcmd -self

    4. Try to run on the master server:

    # nbemmcmd  -machinealias -getaliases -machinename mfp01-2.hs.azdhs.gov -machinetype media
    # nbemmcmd  -machinealias -getaliases -machinename mfp01-2 -machinetype media
