Media Server showing as Client

NetBackup v8.2

Issue: Virtual media server appliance showing as 'Client' under Host Properties > Media Servers, disk are seen as Offline (not Active for Disk)

4x virtual media server appliances, appliances 1 and 2 performing as expected, applianace 3 and 4 seen as 'Client', disks offline.

Troublshooting Steps Taken:

1. bpdown, bpup on both master and media servers

2. Confirm media servers are listed in Additional and Media Servers under Master server properties > Servers

3. Check registry settings, identical between all four servers

4. nbemmcmd -listhosts lists all four media servers, hosts tagged as 'media', ndmp entries also exist for all four servers

5. Run command 'nbemmcmd -updatehost -machinename <mediaserver hostname> -machinetype media -machinestateop set_disk_active -masterserver <masterserver hostname>' nothing happens

6. Advanced Disk and Pure Disk pools exist for all four servers, all same type/size

7. bpgetconfig -g <Working Media Server> reports working media server as 'Media Host'

8. bpgetconfig -g <Broken Media Server> reports broken media server as 'Client of <NetBackup Master>'

If anyone has any suggestions that would be very much appreciated!

  • Please show us output of these commands on the master server:

    nbemmcmd -listhosts -verbose

    nbemmcmd -getemmserver

      Hi, thanks for the responses...an update since my initial issue.

      I managed to bring the 'Offline' servers online by going in to 'Host Properties > Media Servers' and going in to the Properties of each media server and adding the missing media servers to the 'Additional Servers' tab in Server properties.

      I also at the same time removed an old media server that had been decommissioned.

      The issue now is that after some time those servers have dissapeared from the Additional Servers section on each media server...and media server i deleted has returned!

      So almost there...the issue now is, how do i make the changes i make stick!

        When you make changes in Host Properties, then the Registry of Windows server and bp.conf of Linux/Unix server is updated.

        If there are comms problems between the master and some media servers, then this update will not happen. 
        This is why I asked you to run the nbemmcmd commands - this will test and confirm comms with each media server.
        Important to run nbemmcmd -listhosts -verbose

        If you have comms/network problems with some of the media servers, then no amount of Host Properties updates will fix that.

        About the decommissioned media server - what other steps were taken to properly decommission it? 
        Did you go through nbdecommission process?
