Adding new media server to an existing master cum media server

Hi all,

        We currently have a single master cum media server running netbackup 7 in our environment. We would like to add a new media server to this environment so that both the servers act as media servers. How this task can be accomplished. We use an IBM TS3200 tapelibrary and a sepaton VTL.

 

Regards,

giri

    1. Install NetBackup server software on the new server.

    2. Install the latest patch.
     

    3. Make sure the bp.conf (registry) on the new media server has the name of the master

    server. And the master server's bp.conf has name of the new media server.

    4. Add the new media server to master servers EMM DB using the following

    nbemmcmd -addhost -machinename xxx@company.com -machinetype media -masterserver master@company.com  -netbackupversion 6.5 -operatingsystem windows

    6. Also add the alias using the nbemmcmd command.

    7. Create a new storage unit for the new media server.

    8. Recycle the master server daemons

    9. Create the tape devices on the media server or run "Dev config wizard"

    10. Create policies/schedules to use this new storage unit.

    POST CHECK

    1. From master server check if the media server is able to ping

    2. Check if the media server is able to resolve

    3. Issue command bptestbpcd –client <registered media server> -verbose to test the connectivity

    4. Issue command bpgetconfig –s <registered media server>.  This command will list the netbackup version installed on the media server.  Check if it is proper

    5. Issue command bpclntcmd –hn <registered media server name> to check if the host name is resolving correct IP in netbackup.

    6. Note down the IP from step 5 and issue command bpclntcmd –ip <registered media server ip> to check if the ip is resolving to correct hostname in netbackup.

    7. From media server issue command bpclntcmd –pn to check if the its communicating to and back from master server

    8. From media server issue nbemmcmd –getemmserver to check if the media server is able to connect to EMM database in master server.


    Note: For this command to execute successfully the host name given at the time of installation, the host name which is register in the master server, the host name mentioned in master server bp.conf  for SERVER and MEDIA_SERVER and the host name mentioned in CLIENT_NAME parameter on the media server bp.conf should match (This is VERY IMPORTANT)

    Yes the existing media /master can act as it is and the new server will be an addition.

    Use nbemmcmd -listhosts  to validate the list of configured master and media servers in your environment

    Hi Deepak

                Thanks for the info. We are using redhat linux 5.5. Whether the steps 4 and 9 are the same for linux also.

    nbemmcmd - is used across all platforms

    You can find it in /usr/openv/netbackup/bin/admincmd/nbemmcmd

    We have our master server running in solaris but prefer using the Java console for device configuration as it is easy. Java console can be donwloaded from symantec site.

    When we do this whether the existing master/media server can act as a media server.

    Please verify license keys - you need to have NetBackup Enterprise Server license on the master to enable additional media servers.

    The license key that you need for the media server depends on whether the media server will only backup itself or clients on the network as well. To backup remote clients, you need Enterprise Server license for media server as well. To backup itself, you need Enterprise Client license.

    You will also need Library based tape drive license and Shared Storage Option license (if tape drives are shared).

    Before you start installation, ensure forward and reverse hostname lookup in both directions. Easiest to add /etc/hosts entries. Also add media server to SERVER list on Master:
    # nbemmcmd -addhost -machinename <newmediasrvname> -machinetype media -masterserver <yourmastername> -operatingsystem linux -netbackupversion 7.0

    Ensure new media is added to master's bp.conf (manually add if not added by previous step):
    SERVER = <master>
    SERVER = <media>
    CLIENT_NAME = <master>

     

    To install, use steps in this TN: http://www.symantec.com/docs/HOWTO14663

    Most important are the SERVER questions towards the end of the installation, after license key was added:

    Would you like to use (name.domain) as the configured name of

    the NetBackup server? [y, n] (y)

        *      If the displayed (default) media server name is correct, press Enter.
        *      If the displayed (default) media server name is not correct, type [n] and enter the correct name.
        


    Identify the master server that you have already installed, by answering the following question when it appears:

    Is (name) the master server? [y,n]

        *       Type [n] and enter the fully qualified name of the master server. If the master server is clustered, enter the virtual name of the master server.

    When the following message appears, identify the name of the EMM server.

    Enter the name of the Enterprise Media Manager (default: name)

    The master server name is displayed by default.

        *       If you installed the EMM server on the master server, press Enter to accept the displayed (default) name.

    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


    Ensure backup device(s) are visible and usable at O/S level before adding to NBU.
    Next, configure devices for media server (tape) through master server GUI device wizard, add storage unit, config policies....

    If media server will be backing up network clients, add SERVER entry through Host Properties to all clients.
    Again, ensure forward and reverse name lookup.

    Be careful that if your master is not at the latest patch release then your media server should not be.

    The master server must always be at the highest release in your environment.  If your master is at 7.0 GA, don't put 7.0.1 on the media server.  Ideally, you'd upgrade your master first to the latest patch release, then upgrade the media server.

    Also, I didn't see anybody else mention this, but make sure that for your clients that will use this media server, the new media server needs to be listed in their bp.conf files or their registries.  If it hasn't been added, the jobs will fail with a status 59.  The NBU image add_media_server_on_clients can add this to all of your clients for you.

    I had this in my post:

    "If media server will be backing up network clients, add SERVER entry through Host Properties to all clients.
    Again, ensure forward and reverse name lookup."

    Isn't it a requirment (mandatory) to install ICS on Unix Media Server install prior to installing the Netbackup Server s/w?

    ICS/PBX is no longer installed separately in NBU 7. PBX is silently installed when NBU Server binaries are installed.

    See Installation Guide: http://www.symantec.com/docs/TECH127083
